- Hey everyone!
There are TONS of 3.0T exhaust configurations out there, so I figured I'd add another video to the mix with my setup since I haven't seen this specific setup before.
Currently running:
Gutted Cats
JHM High Flow Cat Downpipes with Integrated Baffles
AWE Touring Cat Back
034 Crackle Tune
Complete respect to people out there Frankenstein'ing their exhaust with tons of different parts, but I went with a mostly off-the-shelf config and I couldn't be happier. No drone, great note, barely any rasp, and you can still hear that sweet sweet blower whine.
Will be removing the crackle tune soon and will post more vids of the setup. If you have any questions or comments, drop them below!!!
I ain’t gunna lie kinda love the crackle tune 😂 especially if it really isn’t noticeable in comfort, I’m totally gunna do it
Worked well in Individual mode - set everything to Dynamic except the exhaust haha
Without a doubt one of the best sounding setups. Especially with gutted cats!!!
Nice video man. I'm a fan of the crackle tune but I couldn't daily drive it like that.
Thanks! To be honest I forgot to swap it out before this photo/video shoot as I wanted to actually capture the more natural sound haha. If you're cruising in comfort mode it actually kills them down almost completely.
Most def the best exhaust setup i ever heard
Such a fucking amazing car bro the Audi s4 supercharged engine is goated😭😭😭
Thank you!!! Sounds great
My pleasure, glad you like it!
What a soothing voice bro lol. Car is 🔥
I love this car! Looks too good
love it
Thanks for the kind words!
Thanks for posting this, sound clips are great.
Which midpipes do you have on the car? AWE resonated, nonresonated, or stock? Also just seeing you reinforced the welds on the OEM headers.
Did you run any emissions testing with this setup?
So it was basically just the gutted cats to the JHM catted/baffled downpipes - then directly bolted to the AWE touring stuff out back. I think there may have been some sort of bracket that JHM has that helps the catted downpipes mate to your specific cat back setup. However it's been a while so I can't remember - but if you email JHM they'd make sure it mates up ok to your cat back system.
Emissions would be bad news in any state with them.
@@dom_says gotcha. Thanks much!
Do the JHM downpipes you used have the x pipe in them or are they the ones without?
Gutted cats are key. Test pipes give a god-awful rasp. Mine is gutted cats to cat back Polo exhaust. It's a little too loud and droney for my liking.
Yea 100% agreed! There's something about just opening up the flow of the OEM cats that gives significantly less rasp than the aftermarket test pipe kits.
I think the catted JHM downpipes are what really help tame that drone as well.
When you say you have gutted cats and jhm catted down pipes, do you mean you gutted the jhm catted down pipes after buying them? Or something else
What lip is that called on the truck
Is it safe to run a crackle tune with high flow cats? I’ve heard mixed reviews
Great video man! So to be clear, you have gutted cats up top and then high flow cats down low (downpipes)? Do you think this would work with the ECS valved cat back? I still have OEM cats up top
Heyo, thanks!
This should work just fine with the ECS valved cat back. You’d just need to gut OEM cats and add the JHM catted downpipes if you still wanna run cats.
@@dom_says oh okay cool. Where did you get your gutted cats? But I’ll def consider doing this when I go stage 2!
@@markinopea7548 Got them done locally. Sometimes they pop up for sale in FB groups/Audizine.
perfect.
Got another question for you, What kind of places are gutting cats? I live about a hour from JHM so I'm in your general area.
my biggest question is how did you get it to pass smog?
isn't it obvious? he trail-braked into corner, took an outside-in line, floored it and drove on by like it was standing still. That's how he passed smog.
Gutted cats are the key!
Hey! I know you got a new b9 now, but do you remember if this was using the JHM catted and baffled downpipes with or without the x-pipe? I ask because it’s a $500 difference lol
Without x pipe!
I’m on stage 2+ with 034 I don’t remember seeing any crackle tune option. Could it be because that I’m manual transmission?
notice you are in the bay. did you gut your own cats or did someone do it for you. looking to take the same route.
Hey did you have to put o2 spacers after you gutted the cats and if so which ones did you use
so on a scale of 1-10 how hard was it to gut the cats? specifically getting the cats removed ive been told that you cant get them out without cutting some of the piping off...
What’s you set up suspension and wheel wise? Car sits perfect. Also love that exhaust 👌🏼
Airlift 3H setup with KW V3 rear shocks. At the time was running 19x9.5 ET45 HRE FF04 with 265/35 Michelin PSS! Was a super comfy ride and very drivable.
Was your AWE touring resonated?
I believe the AWE Touring just means it has the mufflers, whereas the track has no mufflers. I think they both come with that rear resonator IIRC.
Where are the tips from and what size are they?
the crackle tune is not appealing....the other exhaust notes were great ....
Hey man im loving the stance of your vehicle, you mind telling me what wheels and suspension your running on this build?
Heyo - I was running Airlift performance 3H with Airlift performance shocks up front and KW shocks rear with Airlift bags. Then the wheels in this video were the HRE FF04 in 19x9.5 et45 with I think 10mm spacers rear.
what rims are those, what brand and model 2:08 on this black A4
Wait, so you left the stock cats there but simply gutted them, AND you added the high flow cat downpipe from JHM? (is that the one with the x-pipe?)
What is the difference between that and replacing the stock cats with test pipes instead. I'm super curious!
Heyo, so ya - gutted and reinforced the welds on the stock cats & added the baffled high flow cat downpipes.
Test pipes for whatever reason are raspier than gutted cats. I wanted to avoid rasp and drone - and was able to do it (albeit pretty expensive) with this setup. I also wanted to avoid the smell of running Catless, and the baffled downpipes + resonated AWE (touring) just give it a solid sound. Hope this helps!
@@dom_says this helps a lot thank you! I'm basically looking to do a very similar setup. I was thinking going for test pipes but I'll look into gutted cats instead
I'll probably try gutted cats plus JHM baffled HFC. And later add a AWE touring catback
How did you get the jhm down pipes to meet with your gutted cats? Aren’t they sold together with the testpipes and have a clamp to connect them?
I had the install done at JHM so they made it work somehow *shrug*
Stock cats? Just gutted them? And put them back on ?
Just gutted, reinforced with welds, and put back on
I wonder if they can actually get proper pops and bangs overun with the supercharger… seems like most tuners can only get it to burble
You can…it blew my other S4s engine though. It’s such a stupid tune…
Have you had any issues running this setup? I've heard about gutted cats blowing welds at the flange and the baffles in the hfc. Looking to copy this setup but concerned about running into issues down the line. Thanks!
I ran the setup for about a year, and had no issues. The welds were reinforced when the cats were gutted.
@@dom_says Awesome, thanks for the quick reply! No issues with the baffles either? Have you since changed the setup?
Any issues with the cats running the crackles a yr later?
Was running gutted cats, so no issues!
Are you able to post more clips? Looking to pull the trigger on this soon. I have test pipes paired with AWE Touring so I’m sure it’ll sound a little different since you’re running gutted cats.
Ya I’m gonna work on some more soon!
Are you in the B8/B8.5 S4 FB group? I posted a couple videos there. Also my instagram is @nerdybeard and I also posted more there!
Best is ecode headder with awe track
How much is maintenance and insurance typically on these bad boys? I’m looking for 2014-2017 s4 but not sure if I should because maintenance and issues down the road. I know others that have had no issues at all.
Kinda hard to give any strong estimates on insurance since it’s so variable - but maintenance isn’t unbearable.
Be aware of the standard 70-90k ish “issues” that can mostly be resolved in the same service: water pump, PCV, supercharger intercoolers, thermostat. Also the cats can go bad even on stock tube before 100k miles. Also, be aware of the DSG gearbox and keep it up to date with service. Motor mounts usually are bad by 50k miles. Most of the above are just standard on Audis and supercharged performance engines - and DSG is just a crap shoot sometimes.
Overall if you are just prepared for the known issues and choose a 6MT or have a solid DSG unit - it’s an extremely fun and potent platform!!
1 of them
I need more clips! You have a Instagram or more videos?
Hey! Can you describe how the smell is? I must’ve watched this video over 10 times 😂
Yo! So the smell is pretty normal for a HFC. Noticeable when you get on it, but not nearly as bad as a complete de-cat. With windows down you get a little scent, but with windows up it's non existent.
Hey by adding the jhm high flow cats help eliminate the smell of gas which was coming from the test pipes ?
did you gut the JHM downpipes? your description is a whole mess of contradiction bro lol. not to say your S4 sounds amazing and glad to hear you dont have any rasp or drone either
Gutted factory cats*
dom nice work dude, how can i contact you i mean number or email need tons of advice with my audi
Hey thanks! Why don’t you gimme an overview here and I’ll try and help out. Also try out Facebook groups for B8/8.5 (the only reason I use FB lol) for advice and help!
