Removing Rusted Honda Exhaust Fasteners

- In this video I show you how to remove the stubborn exhaust nuts found on 90s Accords.
I also include the replacement of a front flex pipe on a 1997 California emissions model Accord since that's the reason I needed to remove them in the first place.
They're usually found holding the catalytic converter to the rear exhaust pipe on more common federal emissions model Accords. On this Accord they hold both ends of the front flex pipe to the exhaust system.
While the 10mm heads on the nuts may lead you to believe the studs are a small diameter. They're actually much larger in diameter than they look.
The small heads on the nuts give you less surface area to grab when removing them and increase the likelihood of rounding them off. Especially if they're badly rusted.
Don't attempt to reuse the old nuts purchase replacements from the dealer they've been revised with 14mm heads that will make removal much easier in the future.

I used ruclips.net/user/postUgkx4ynqaujg7rZKFapA8s29kTpRszJGa3-K this for the first time today to replace the front wheel bearing on my rwd 98 dodge dakota. This had absolutely no issue removing or reinstalling the lug nuts and it took off the axle nut without any struggle. Sounds like it's got some muscle to it. Time will tell
I was replacing the catalytic converter on my '02 Accord and two nuts began stripping... Watched your video, went to Lowes for a propane torch ($40) and the extractor (5pc kit for $20). Worked PERFECT! All off with no stripping!!! I used the torch about 50-60 seconds on each nut with straight propane from my green camping tanks. They did not glow red like your video, but it worked just fine. Thanks very much!!!
In case you don't have a torch, another way of breaking rusty nuts is to take your car for drive until heated up and than spray it with ice cold water.
This will crack the rusted-on bolts and nuts. You will here a pop, that's when you know it worked. Now you just loosen and viola! Good luck!
Two Seasons great tip,thanks!
Great video. My car has been needing this for a while. It’s good to see it isn’t too difficult. Thank You.
Very well done, now I know the shop must do mine. Thanks for the info
Thanks for the video. Only other thing i would highly recommend is using anti seize on the threads before installing the new nuts or bolts. Or replace with stainless steel ones. Next time you take it apart it will make it way easier
I usually do but I forgot. That being said I've had mixed results with anti seize on exhaust bolts sometimes it will help other times it doesn't make a difference and it's time to either heat it up or cut it off with the torch.
In any case applying it doesn't hurt.
This was "definitely" good stuff to know! Haven't tried it yet, but on my way to get torch, extractor, and bigger bolts for the converter. Thanks. 🤘😎👌
This gives me confidence to do the downpipe on my '04 shitbox.
Thanks for the info man. I appreciate you taking your time to show us. 👍
gr8 job. what i would do in adfition is put some copper pastę on these treads so you will not have an issue removing these bolts in future. but in general good job :)
Yeah I forgot in this rare instance always a good idea.
Just keep it off your hands or all of your tools will look like the tin man was handling them. The smallest dab of the stuff spreads like the plague.
Bushougoma that’s aluminum paste. Copper paste on exhaust. It’s MUCH thicker and doesn’t spread so easily.
I don't use acetylene very often but it's a great tool to have in reserve. I've seen new electric induction devices that are possibly safer in tight spaces, but of course they don't offer the other (brazing, welding) options.
Induction heating works well on assembly lines where everything is planned out but it's pretty impractical for everyday use.
You'd need different size coils for different jobs and I can see the coils taking up too much space in real tight quarters. A flame can get pretty much anywhere a bulky coil can't.
Not to mention the need to keep the coil off whatever you're heating. It's easy when the coil is on a table but not when you're holding it in place by hand.
I don't see it replacing fire any time soon :-).
my propane tank torch wouldn't get it red hot so I had to heat it for a long time. it worked! cat to midpipe flange bolts were stuck. should have tried my moms creme brule torch lol
Lol
Hey whay kind of socket did you use to get that nut or bolt off
Can one use a stripped bolt remover on a bolt that hasn't been stripped? I like your method there to remove the bolt with a wrench and remover. It would fit better into a tight spot. Thanks.
My kind of guy. Thanks bub
Excellent video thank you for helping us out
I have these tools because I tried plumbing.
YES!
Awesome!!!
Thanks for sharing!
loved this idea, great upload thanks
Man you are on a roll. Keep up the good work bushou!

You can and Honda sells replacement studs or you can replace them with nuts and bolts.
But to get the old studs out you'd need to heat up the flange around the stud until it's glowing red then you can drive out the stud with an air hammer or punch and mini sledge. The studs are splined on the ends which prevents them from turning and gives them an interference fit.
You can heat it up with a hand held torch but use Mapp gas (yellow cylinder) instead of propane and you also want a high intensity torch head. They are self contained with a push button ignition not the cheaper type of torch head that requires you to turn on and ignite the gas manually.
***** Thanks for confirming it's possible. Can you tell me what the diameter of the studs are?
*****
On this vehicle M10 X 1.25. 10mm diameter 1.25 thread pitch.

Thank you. Mine appear to be the same size (49 State Emissions). The exhaust nuts are very small. On another note, if you have the time, naval jelly will eat that rust away in a couple days. I'd say how you get it inside the threads but I don't want to give away my trick so easily. Most people can figure it out :)
Man I need to invest in a acetylene torch lol my propane torch didn't do much for me last time.
my problem is at the resonators bolts and in that area. it's so frustrating
Great video, thanks so much for the tip
Used an oxy-acytene torch on mine. The broke loose pretty easily with a 12 mm socket.
Thank you!
What year is Honda? I have 2008 Accord is it same flex pipe?
did you buy the flex pipe from the dealer? or online? can you share the link?
So much easier when you have a torch.
i have a 96 accord and i think i need to change my flex pipe...where can i find one?
Dude, thank you
Awesome..
My local muffler shop wouldn't even touch my rusted cat. Where is Cali are you located?
Nice Job great video
My additional thought...
Run a die down the threads it will clean them up
Use anti seize on it, I would copper for this repair
Hello I have a question when I run my car and stop you here popping and fessing from that like water or you can say antifreeze leaks from that but little thought anything thoughts ???
I have a 96 lx 4 door. Can I use a straight pipe and get rid of that pre cat I can't find that exact flex pipe anywhere. Big hole in it
ive got a 2010 crosstour and i have to deal with the upper cats and the downward facing nuts, if you can even call them nuts any more, tight quarters with the subframe makes even spraying those with penetrant insanely hard so I have no clue how im going to get a torch in there let alone hammer on an extractor and use a box end on them.
I also got an estimate on new 9 studs and bolts, nowhere near 32 cents each, they quoted me 230, for 9 nuts and bolts
Is propane effective?
Will a propane torch get the bolts hot enough?
With a type Z torch head and MAPP gas maybe all depends on how much metal there is to heat.
Instead of heating up the bolts, can I just let the car run for half an hour; and let the bolts get heated up themselves? Will the bolts get hot enough to be removed?
The exhaust gases will never get them as hot as a torch. You want them to glow cherry red they will never reach that temperature in normal operation.
Would a bernzomatic torch work?
The addition of pure oxygen to acetylene, propane, or MAPP gas is what gives you the hotter flame to quickly heat up parts.
You may be able to get the parts hot with a portable torch but you need to heat them until they glow cherry red which is around 1400 to 1500 degrees F. In many cases the surrounding metal will conduct the heat away and dissipate it to the surrounding air faster than a propane or MAPP gas torch can heat it up.
how long would it takr without acetylene
*****
Can't say it depends on a lot of factors it may take a few minutes or you may not be able to do it at all.
You want a type Z torch head and MAPP gas (yellow disposable cylinder) that will give you the best chance. They're the type that doesn't require a manual spark lighter because they have a built in ignitor.
The tiny pencil flame on a cheap brass torch head won't be enough.
What’s the aluminum meshy part of the exhaust called?
That's steel braid it helps reinforce the internal flexible pipe. If the braid has rusted away and the flex pipe isn't leaking already it soon will.
I am doing repair work on my 2002 Toyota Corolla here in the rust belt,there isn't one nut or bolt on the exterior of this car that doesn't have rust,my problem is...how do I prepare a rusted bolt or nut for removal that I cannot use heat on ..for instance a bolt that is holding a plastic panel in place or the bracket that holds the radiator in place,I have snapped both of those bolts even after giving a good soak with PB Blaster? any suggestions?
You can try letting the penetrating oil soak overnight it gives it more time to wick into the threads on stubborn fasteners.
You can also try tightening and loosening the fastener in an attempt to break up the rust on the threads.
Your options are limited when you can't use heat. The best way I've found is to hit it with some penetrating oil let it soak and use an impact more often than not it will come out the vibrations from the tool will break up the rust.
If the head shears off you've given the fastener it's best shot and you're going to have to extract or drill it out anyway.
***** Thanks
So both the bolts broke and the nuts on the other side are rusted on. How do I get the nuts off? There’s not much room to hammer them out?
If they're original those are studs pressed in from the other side. An air hammer with a rivet bit will get them out.
Without air tools heat the flange red hot and beat them out with a mini sledge if they're next to flush with the flange use a flat punch.
@@Bushougoma thanks for the reply. I don’t have an air hammer and not enough room for a sledge hammer so I think I’ll take it to a mechanic with a hoist 😂
@@flipperdoo22 They make small 3 pound ones for tight quarters. Didn't mean a full size one.
But yes air tools would be the best chance for success in this situation.
Hi, I am looking to replace my 93 Honda Accord 10th Anniversary Edition's Flex pipe. I would like to do it myself without using the flange. I'd like to cut the current one off and put a new one on. My question is, do you know what size the inlet/outlet of that pipe is? I've seen 1-3/4 and 2-1/4. Mine looks as if it is a 2" and I can't find one that is a 2". Can you help me with the exact measurements of that pipe or a pipe that would work? Thanks for your help.
Exhaust pipe is usually specified by outer diameter by most manufacturers the wall thickness is determined by the gauge.
Just measure around the old pipe with a fiberglass measuring tape and divide that by pie to get a rough approximation of the OD.

I think my 14mm bolts are now 6mm wish me luck👍
Can I do this with a propane torch
Your typical propane torch with a disposable cylinder won't be able to heat up a large enough area. Most of them have puny pencil flame tips which while great for soldering copper aren't useful for heating parts. There's no substitute for a real torch kit but they're not cheap.
Can I use a butane cooking torch?
even propane isnt strong enough, you really need to use those garage torch that has different gas mixes (i dont know what are he mixes)
would cheaper propane torch would work for this application or oxy torch is must?
Propane doesn't burn hot enough unless you mix oxygen with it.
Many people who need a torch strictly for heating metal and cutting substitute acetylene for propane since acetylene is more expensive. You can't weld with propane though.
I had an axle nut from hell that i tried using a propane torch on, it didn't do anything, it's just not hot enough. After I bent my breaker bar from jumping up and down on it I ended up just cutting the nut.

Axle nuts and crank pulley bolts the two places where you'll wish you had impact tools.
They can be pure evil to remove if you're just using hand tools.
You have to be careful when heating axle nuts. You run the risk of damaging the rubber seals that keep the grease in the wheel bearings.
Since re packable adjustable bearings aren't commonplace anymore that means new bearings if the seals get destroyed.
what is the cheapest but acceptable oxy kit? which one do you use?
For occasional use you can get by with one of the tiny kits that contain a 10 cubic foot acetylene and 20 cubic foot oxygen cylinder.
Don't expect to do anything other than heat up stuff with this tiny kit. You usually get the torch, regulator, and tanks in the kit.
As a rule of thumb you want the oxygen tank to be double the size of the acetylene tank.
For the following setups below you buy the torch and regulator in a kit but the tanks are bought separately.
The next step up would be a 40 cubic foot acetylene (B tank) and an 80 cubic foot oxygen tank.
Then there's the setup I use a 75 cubic foot acetylene tank and a 120 cubic foot oxygen tank.
Renting the tanks from a gas supplier is a waste of money it's better to own the cylinders.
There's a higher upfront cost but the rental fees over time will eventually add up to the cost of the cylinders in the first place.
Where did you bought it the exhaust fastener ???
From the dealer for a few cents each.
Bushougoma thanks for answering me
Bushougoma they dont have it anymore its been discontinued from #nashville TN 😞
This video is cool and everything...but it does NOT help the average backyard mechanic that doesn't have a torch like in this video or professional tools...most backyard mechanics use tools from sears, harbor freight etc...and we do this to save money from labor costs from a real mechanic shop..especially at inspection time or a break down ...not cause we like it....tired of this videos that doesn't really help the average guy
smith wesson I've done other videos where I've outlined how to cut the fasteners off which is your only option if you don't have heat and sometimes heat doesn't work and cutting the fasteners off is the only option. In this case heat worked and saved me a lot of time.
Working on a rusty exhaust system without some type of torch or abrasive cutting tool is just setting you up for failure a ratchet set can only get you so far. Harbor freight does offer a small torch set for a reasonable price by the way (even less with a percent off coupon) it's something that will pay for itself every time you have to work on an exhaust system.
Think of it this way take the money you're saving on labor and purchase some tools to make this job and future jobs easier. Tools are an INVESTMENT in your independence from those shops when you hit an unexpected brick wall during a job the ability to complete that job often depends on what tools you have in your tool box. If you're not willing to make that investment or the cost of the tool in question is too high to justify maybe going to a shop makes better economic sense.
+smith wesson You might consider a propane torch attachment like this:

I've removed many rusted nuts and bolts using just a cheap hand held propane torch.
paul johnson I've been told that propane doesn't get hot enough.
Bushougoma would an impact wrench work?
Torch them red hot you say??? Oh ok. Lemme go out and get a whole ass oxy/acytelyne torch just to remove some rusted ass bolts
32 cents at the Honda dealer....not any more.
