The ebwerks uses race mufflers, it’s a straight through design no flow restrictions. The x pipe isn’t as nice as JHM cat back system tho, a bit restricted in comparison to the JHM catback. THE Ebwerks exhaust is very loud if it’s non resonated but sounds awesome none the less.

Curious to know if there are any dyno stats that show the EBWerks x-pipe is less efficient… i had heard its actually a true x-pipe. I am worried it will be super loud, but the front section of it is hot swappable, so i can always add resonators.
I"m not sure abotu that…IIRC they couldn’t find 2.75" mufflers. So they tried to copy the ones that JHM uses…but Sebring told them to go fuck themselves.
So they ended up using the same ones as another exhaust…2.5" mufflers.
Basically a restriction right at the end of the exhaust. Not sure I would ever buy that.
When we see there are about 6 or 7 JHM supercharged RS4s out there with 1/4 mile timeslips…and only 1 is running really poor times AND traps, it’s not likely a coincidence that that one has an ebwerks exhaust on it.
Just look at the frigging thing. Then look at the one JHM designed. Not even close.
I bought the system second hand new just the catback, it was in prices mind you and we had to modify it as it was not resonated . The tubing is 2.75 inch the mufflers are 3 inch diameter straight through design . Maybe something got changed along the way, i don’t know? If i can get my hands on a used jhm system i will do a comparison. Just by looking at the JHM Xpipe its obviously a more efficient design no doubt there. Would be a interesting comparison between the two!
*pieces
Sorry I remember one of the mufflers they went with in the beggining was restrictive. I guess they changed to the stright though
The exhaust was always said to sound way too loud and much like the superchaged car with low trap speeds a few others reported they felt the catback of EB works wasnt any better then stock for performance
I noticed an immediate improve and response, but then again I’m not running cats. Like i said, if I can get my hands on JHM system I’ll be more than happy to do a comparison between the two! 
See its these kinds of things that can lead to unintended miss-information in the market… Are the mufflers restrictive, or are they free flowing? Its a 2.75 system all the way through… how can it be comparable to stock? Is the RS4 thats SC’d really running low traps because of its exhaust? Has that been proven, or merely speculated on? Maybe it needs a carbon clean… im just saying it seems unfair to say with certainty that its the catback.
When i get the system in ill get some pics of the mufflers before anything gets installed. I will be running no cat’s so im sure it will be loud, but some resonators may be in order!
Sometimes I feel like you guys just make this stuff up because you never liked BenSti or that he made a catback of his own.
Back then I believe it was said that their catback was nearly a direct carbon copy of JHM’s and how he blatantly ripped them off. Now all of a sudden it’s “not even close”.
And suddenly you guys saying there were reports of subpar performance. The only people that bought them were pretty much all friends of Ben and I never read poor reviews from them since they all love Ben & chose it to be “different”.
Honestly I don’t think itll make that big of difference. And I’m not actually saying these claims aren’t true of the EBwerks design, but you guys do have a tendency to drop a bunch of facts & never link the source and I find some of it interesting since I’ve never seen or read these things over the years
where the fuck did this come from?
no offense but that sounds like bullshit being fed to you by an ebwerks employee. And since there’s only one, we know who that is.
The JHM mufflers are made tailored for the JHM exhaust by Sebring. They are straight through, perforated core design. They are not fibre glass packed (is this what you meant by steel wool on the ebwerks?) which is old fashioned and as APR learned, not ideal. The JHM designed Sebring mufflers are by far the best quality exhausts we’ve seen available on the 4.2 platforms in the 8 or so years they’ve been out.
Sometimes the information flowing is just…bad.
Here’s an example of a sebring tuning muffler

here’s the core
Wrong, the motor came from me, it has nothing to do with FT
I think it is hilarious that people think that the exhaust brands are going to have a massive affect on performance.
If you have a 2.5" exhaust on a S4 and it is comparable in spec to another IE Magnaflow vs AWE vs JHM FI, assuming they are all similar in restrictions (no cats, non resonated etc just same options) why do people think that one design is going to yield massive gains in performance compared to the others? Sure x-pipe and the muffler design will affect performance, but not tens of horsepower or dramatic trap speeds.
If someone with X brand 2.75" exhaust didn’t trap well compared to other cars with comparable setups, I would be looking at the engine setup and driver competency before thinking a muffler design cost him 5 mph lol.
…lol you are connected to FT so how is that wrong?
Want to rethink that post for a minute?
JHM made a 2.75" RS4 exhaust with an x-pipe crossover, and Sebring 2.75" straight through perforated core mufflers with oval tips
NOBODY in the industry made anything similar.
GMG, Milltek, etc. were all 2.5" and no x pipe
MTM was 2.75" but no x pipe, different mufflers and quad tips
Then along comes ebwerks seizing an opportunity when JHM was shifting over to Fast Intentions to have them hand make the exhaust. For a year JHM wasn’t selling while Danny got set up, so EBwerks copied the JHM design, and sold their own to the guys on the forums who were tired of waiting for JHM to be ready.
ebwerks went with…shockingly…a 2.75", x pipe crossover, 2.75" sebring mufflers with oval tips
If you don’t understand how that is a straight copy job, I’m not sure we’re on the same wavelength.

When it finally came out, the x pipe was poorly designed, and then they had to change the mufflers to the ones GMG uses (which were 2.5" and bored out to fit ebwerks).
We saw a couple of cars on the dyno - made ZERO power over stock exhaust (meem, mickf29)
We saw a couple hit the dragstrip - Mickf29 was actually SLOWER than stock exhaust when he had his ebwerks exhaust on his car. DenisRS4 in California is JHM supercharged, and from day one his car has not matched all the other local cars that hit the same dragstrip. He has full ebwerks.
Should you maybe reword your post to “what specifically are you guys referring to with respect to EBwerks underperforming? I don’t remember” rather than questioning people without doing your homework.
I don’t think I need to ‘link to the source’ because you were busy on the B6 S4 forum and are out of the loop. Want me to draw up a precis for everything that has every happened in the RS4 since before you started reading? Do your own homework. I don’t give a fuck what exhaust you buy. I just don’t want someone sharing some bullshit saying the ebwerks are better quality because they have steel wool (LOLOL) than the JHM ones. WTF…why don’t you ask that guy to corroborate that wopper.
who said anything about ‘massive’? Who said anything about 5 mph of trap speed? Be careful, you’re throwing around bullshit to make a point. That doesn’t last long here.
All I can share is that we have seen ebwerks cars pre-post performance tested and pre-post dyno tested, and they’ve all done pretty poorly (those who have shared anyway)
Sure there can be a number of variables, but I think it’s pretty interesting that there have been multiple cars show virtually ZERO gains from ebwerks.
My car picked up about 2.5 tenths of ET and 2.5 MPH at the dragstrip with just my JHM downpipes (catted) and catback exhaust. And my stock benchmark time was the best ever stock RS4 1/4 mile time (12.75@108.36) so there is literally no tougher benchmark to compare my exhaust times to.
If you want to share some performance gains for ebwerks, please do.
You’re really reaching for a connection

I’m definitely interested to do a comparison!
Perhaps next year we can meet up at the strip and see the difference between the two systems? This way we can see how much more efficient the JHM system is! The JHM Xpipe design is larger in diameter and has a smoother transition then the Ebwerks.
