It's refreshing to watch someone who gives absolutely no fucks about monetization and makes informative, well put together videos with scientific explanations to clarify everything. Cheers, mate.
I agree except one little thing , I'm from America. So to me this was the most unclear, clear and concise explanation I've heard so far too... lol jk jk great video man
At first I was like “What?” Then I was like “huh!” And at the end I was ready to teach a class on the mechanics of exhaust systems. Well done sir, well done.
There is a 4th reason to do exhaust wraps - thermal control. I have an air cooled dirt bike where the header pipe is very close to the cylinder body and the carb bowl. Instead of making heat shields, a good wrap helped cut down the radiant heat soaking the bowl - and maybe helped keep a little heat out of the cylinder itself. It also helps with keeping my right leg from roasting, so bonus!
Very good point. On one of my Harleys the exhaust is right near the oil tank. And it burns the shit out of my pants. But the main reason I want to wrap it is to keep more heat off of the other shit. For example the oil tank.
This is what i was wondering about as well. Let's say you have an air/oil cooled bandit with the headers straight in front of the block, would an exhaust wrap help cooling the block, since the moving air wouldn't be heated as much by the headers before hitting the cooling fans of the block?
Wow just watch this as I am investigating wrapping my 1997 Kawasaki VN800 after converting to a bobber and wanted to understand the pro's and con's and watched other vids but yours was excellently presented easy to understand well done.
This appears on my recommendations since weeks. Now that I opened it finally I hope youtube is being satisfied at last and stops recommending it to me.
There is a video here on you tube where a guy is using a hand held temperature sensor and it clearly shows that wrapped pipes are hotter than unwrapped pipes so your chance of getting burned is now greater. I was going to do the same thing till I saw this video.
@@bb2na473 there is definitely a change in temp. I have a wrapped thunder header on my bike and believe me you can feel the heat so much more after wrapping the pipes.
@@edkay3601 there is a difference between touching hot cloth and hot steel. Heat will transfer much faster to your skin from the metal than it will from the cloth. So even if the cloth is hotter, it won't burn you nearly as quickly as the metal. If you don't get what I'm saying, think of the difference between air and water. You can put your hands in an oven at 350 degrees without getting burned, but if you put your hands in water boiling at 212 degrees, you'll get burned very quickly.
Thank you for boosting my confidence, I feel more intelligent, of greater interest, my looks improved, my speech ability stronger and my dress sense sharper than before, thank you.
My thunderheaders are ceramic coated but still required shields to keep from frying my right leg. After a few years I removed the shields and wrapped them. I prefer the look and reduction of labor when I don't have to fool around with the shields. To those that worry about corrosion just don't let the wrap stay wet on the pipes any longer than needed. They dry out quickly with minimal steam production once the engine is running. Been running wrap for years now. Glad to hear that it helped performance a small bit. Thanks for the clear explanation.
*Pro Tip:* Before wrapping your headers, scuff them up, prime them with high temp primer, then paint them with high temp paint. This will protect them from moisture/corrosion.
You're a cluey fella. Keep up the videos, perhaps one where you pull apart different 2stroke japanese power valves and explain each. I really enjoyed the Kx series.
on my husq 510 i just did a double layer 25 cm long next to my leg. no change in performance but now i dont cook myself when im stopped at a traffic light... 3 years later and i havent had any problems
Thanks Matt the only guy that did it that I have asked was on a v twin cruiser and he said it was to avoid burning his leg. I used to see a lot of two strokes with home made race pipes at club races and they were invariably black and metal. Didn't know it caused corrosion, thanks.
Thanks for such clear and precise explanation. I just bought my first 125cc and the previous owner had wrap around the exhaust. Made me curious about its puepose.
I had exhaust wrap on my 125, I painted the exhaust with VHT paint first and cured that, then I applied the wrap, after a very wet and horrible year I removed the wrap as it started to go white from heat and found my exhaust looked just as good as when I painted it. I think a lot of people forget to paint or protect the metal, as said the wrap will hold water when not running and so on.
Exactly. Also, never put the bike to sleep if the wrap is wet. (Caught in the rain on the way home) Let the bike idle and the exhaust wrap will be bone dry in no time.
P.S some RC boats with 2 strokes have water cooled exhausts some use a wrap. For an engine with crazy porting and a narrow power band presumably the wrap is too stop the pipe from detuning?
Going to wrap the exhausts on my Guzzi great explanation think it would look good on my V9 Bobber is it best to overlap by half or a third if sumone could reply ide be most grateful .😀
Thank you for the informative video that isn’t filled with bullshit blah blah, theatrics and annoying music. There are people who look into RUclips for information and testing, or even instructions on how to use a product or want to know their experiences using it and the down sides. Sir, you have delivered, enough said....
Really great video. I did wondered why people wrapped exhaust other than for looks. A brilliant explanation. I have to say I do like the look of exhaust wrap.
@@viarnay -Could be one historic reason for general aviation, those with internal combustion, having a few issues contacting dirt... more often than planned ;}
Would be a nice video for your bike tech series (exhaust flow). You say faster exhaust flow = better. But what about low rpm torque etc. My bandit has great top-end power without baffle but runs very rough at idle/low rpm. With baffle it's much better low but worse on top. Valve overlap, pressure waves..eetc?
Very good point, you've caught me out WP! Understanding the complex world of exhaust flow, back pressure and pressure/vaccum dynamics is hard enough. Its presenting it in an easy to understand way without a load of 'well its kinda like that but in this example thats not quite true' or say 'sort of' alot lol This is a subject I'm gonna have to actually write a script for - oh the joy. but very good suggestion that I will have a crack at. - matt
I like the looks of the wrap and I think it's more appropriate for me than the ceramic, I do ride it on dirt/mud and rocks, so the protection is the most important for me.
I wonder if the protection is as good or better than shields. Does the wrap keep the heat in the pipe and feel cooler on the legs than the shield ?? Thank you for your generous consideration, Sincerely ........................
Hey Matt... probably a stupid question but, what about ceramic coating and wrapping? I ask cause I like the performance and anti corrosion aspect of the ceramic but wonder if the wrap would be good for protecting me and my gear from burns and in cars heat soaking the engine bay. Cheers
I have a Triumph GT sprint which puts out a lot of heat from behind the fairings. I wonder if the heat wraps would nullify some of the heat to make it worth it?
Excellent description...could you continue the explanation about speed of the sound wave/efficiency of scavenging, with respect to other aspects of the exhaust...mainly the impact on scavenging of removing or downsizing the cat, and the impact of pipe diameter? That’s the age old problem many people try to solve to increase power (along with tuning the length of the exhaust). As it’s possible to buy E marked cats that are much smaller than OEM, and which fit inside the diameter of the header pipe, it’d be interesting to know the impact of removal or downsizing on scavenging : )
Just to toss in my 2 cents, in car applications it does a good job of keeping the temp down under the bonnet. I put in on my MG's header for this purpose. Also the protection from burns factor if I am adjusting carbs while the engine is hot.
I'm planning to wrap my xmax 300 scooter cause the exhaust pipe produce so much heat that it could warm up my bottle water in it, does it have any bad effect?
Done a wrap once on a Yamaha XT225 I had but just on the first portion of the exaust. It looked awesome and people thought I had modified the engine somewhat (which I hadn't). The plus side for me was that it eliminated the heat around my right foot which in a hot country like Brazil, it's a big gain. Cheers and excellent video mate! Can't stress this enough. Love your work.
I was waiting to hear you mention something about tuning after a wrap, because i would think the engineers knew there was 10% exhaust gasses left and if you change that ratio by wrapping, wouldn't you need to re-jet or at least adjust air-fuel mix accordingly ?
Thanks for posting this useful video. I have a RE continental gt 535cc and was thinking about wrapping the exhaust mainly for enhancing my bike's looks. Would it effect the fuel efficiency and or has any other disadvantages apart from what you mentioned? Thanks in advance
The simple answer - no. The exhaust scavenging dynamic would change, but nothing you'll notice EVER. As i stated in the video, exhaust wrap has benefits, but so slight that apart from cosmetics it doesn't really change anything. - matt
Always the best place to come for genuine practical info! What do you think about using this to reduce the average coolant temp on my R1? I’m conscious that the headers are really close to the radiator and it does run hot…. Failing that is it worth using it around the underseat exhaust pipes to cool me arse down?
Here in Vegas it never rains so maybe nice here. I could see how on the coast with high humidity and frequent moisture that it could ruin pipes over time. Long live the Vegas riders!
Exhaust scavenging 101. Thus why small header opening and exhaust getting bigger towards end to help speeds and hopefully create small vacuum before intake opens. Heat shields may work in some cases to block heat. My 360 has wrap so i don't burn my leg. Great video.
Very well explained. I had a 500cc Scooter where the frame would get incredibly hot in summer on long rides. Suddenly you would loose power and had to wait for it to cool down again. I found out that the exhaust was heating the frame and the frame heated the ignition coil. Wrapped the exhaust and the problem went away.
I had a problem with wire harness melting from exhaust heat and the wrap did the trick. I did the exhaust with wrap and used spark plug heat shielding (same make as the wrap) and works great. The intake manifold stays cool as well witch doesn't help fuel milage but improves torque for when you have to hall 1000 pounds of tractor, rider, and equipment up steep hills👍
Hi Matt, Is there a measurable difference to radiating heat on components near exhausts between exhaust wrap and ceramic coating? I am building a turbo bike at the moment and trying to decide what method is better at saving components near the exhaust.
Is there any great risk to keeping the exhaust gases hotter for long as far as the engine goes? Are the cylinders likely to get hotter and could it potenially damage internal parts?
My pipes on my 2012 HD Fatboy lo burns the inside of my upper right thigh during the warmer months. I ONLY want to wrap the part that is near my upper right thigh. If I only wrap [and spray] that 8-9 inch part of the exhaust from the header down, will it hurt to NOT wrap BOTH pipes? Again, this is not for power or looks, just for protecting my upper right thigh and the bottom of my right saddlebag [over the top muffler]. What would you suggest?
Would it not also aid with cooling and power by allowing more cold air into the combustion chamber? I dunno shit about engineering though so would love to know if or why I'm wrong
So, it's been almost a year. Any follow-up video on the state of the wrap after all this time? I'm REALLY curious to see if there's any corrosion, etc. I just bought some exhaust wrap and I don't want to have to buy new pipes in 2 years...
No not yet, there will be though. I'm also running a test between, wrapping, ceramic coating and enamel paints, which will be up in the future once enough time has passed - matt

You need a doule skinned heat shield with an air flow between the two.

Hi Matt, Is there a measurable difference to radiating heat on components near exhausts between exhaust wrap and ceramic coating? I am building a turbo bike at the moment and trying to decide what method is better at saving components near the exhaust.
The short answer is probably not. I'd guess that the wrap is a better insulator than a coating due to thickness.
Is there any great risk to keeping the exhaust gases hotter for long as far as the engine goes? Are the cylinders likely to get hotter and could it potenially damage internal parts?
No, dimple because the engine is generally overcooled by design.
My pipes on my 2012 HD Fatboy lo burns the inside of my upper right thigh during the warmer months. I ONLY want to wrap the part that is near my upper right thigh. If I only wrap [and spray] that 8-9 inch part of the exhaust from the header down, will it hurt to NOT wrap BOTH pipes? Again, this is not for power or looks, just for protecting my upper right thigh and the bottom of my right saddlebag [over the top muffler]. What would you suggest?
Not really - there is always as temperature between each cylinder - especially with V twins
Great video. Thanks
Would it not also aid with cooling and power by allowing more cold air into the combustion chamber? I dunno shit about engineering though so would love to know if or why I'm wrong
Very Very well said
thanks for the comment dude - matt
