Let us know how it goes

[brad65ford]

Will do Mike, I almost purchased a 3 1/2" resonator yesterday but really want to see what happens with the Catted DP's I order from you sounds like first.

I remember a catless downpipe on my old evo ix's, wrx, sr20det, srt4, etc. there was at least 20-30 hp gain with quicker spool and no issues with overboosting, unless I installed a bleeder valve or an electronic boost controller and went too aggressive. But that was mitigated by mechanical internal adjustable wastgates whereas todays cars are electronically controlled.

No, I can't. And I don't have any data logging capability yet, but I've read here that the ECU does more to keep power output consistent over varying weather and altitude. If that's true, then I'd assume it could respond similarly to less restriction in exhaust such that without a tune of some sort you won't see as much of a power gain from bolt on parts as older platforms. Maybe same power with less boost though?

I'm very interested in the whole overboosting with catless downpipes and JB4 "topic", because there's only anecdotal reports here and there without any real data shown to support people's claims one way or the other. That's why I asked if you have direct experience.

So far from my research:

AWE - solid exhaust and good price but everyone says it is quiet without dp seems to be made in USA

R44 - titanium but made in Asia and bad customer service reports from others on here

AA - seems decent but parts may be made in Asia and sold at a premium

Akrapovic - excellent system and parts but really really expensive, could sound better

Fabspeed - alot of horror stories and parts made in Asia

Eisenmann - good quality/fit made in Germany a bit pricy

Valvetronic - bad customer service, some people here saying pipes rusting

Remus - sounds good and good price as well but may drone apparently

This is the best exhaust according to Reddit

I’m going Eisenmann. But I’m biased and following “tradition”. Have a E Race on my E46 M3 and E90 M3 going to get it for the G80 also.

Are you doing race with resonated mid pipe or without? I want to do this but fear unbearable drone. I was advised sport with non resonated mid pipe is basically the same as race with resonated mid pipe.

Im wondering if anyone has ever heard the Valvetronic Midpipes in Titanium and Stainless side by side. And is the 1k difference worth it? Im assuming Ti would have a bit of a higher pitch, that ti systems usually have, but can that really be picked up with just the mid pipe? My car is about 2 months out so I want to order soon!

This is where I’m confused. I have asked IND sport vs race but obviously I’m getting descriptions from the mind of someone else so it was hard to make a decision. End of the day the Eisenmann sport is like a boat anchor lol, if it’s anything like my other Eisenmanns. I’m going race with a Super Sprint J Pipe with resonantors which has already been ordered.

Sweet I went similar set up, Eisenmann race but with with SS mid and H-pipe.

What's the benefit of super sprint over eisenmann mid? It will fit right? I see some of them have sport cats built in wonder if it throws cel

I had that same convo with them, I think I may lean race too because the sport is huge. Why super sprint instead of eisenmann mid? Because of the sport cats? Also it seems it won't be out until January?

I spent a lot of time researching which exhaust system I wanted to go with. Remus was high on the list for me. Heard many complain about drone so I didn't go with it even though it does sound really good in videos.

Titanium Valvetronics was second on my list, absolutely loved the sound of Soon's car, but heard feedback from many that you can only achieve similar note if you have a 6MT.

A lot of people were hyping up the AWE Exhaust, and I didn't make a purchase until that was released. To be 100% honest, I was not overly impressed with the sound of it, was a pass for me.

Ended up finding a video of slum dog vics car running the TFL Italy Race exhaust. Spoke to few people on IG that have went with that exhaust, and I think it is severely underrated. It sounds incredible, many people who've heard it have loved it always ask what it is.

Few clips I have of it:

I like the sound of a single Midpipe over a X pipe personally. It’s deeper sound.

Seems like this sounds the best. Which mid pipe?

[R44 Performance]

We've had great responses from our system, quality and sound wise. At the price point also it is definitely competitively priced.

Development on this was all complete as well as rendered in the UK and final production was sent abroad for quality, cost and efficiency purposes.

Happy to help anyone looking into the system. This system is half the weight of the stock system which is a huge saving.

Have a listen to the video below (doesn't do it justice as most videos don't).

I visited Zach at his shop in the UK and loved the sound of the exhaust and ended up ordering one. My car arrives in a few weeks and will upload sound clips. Additionally I will note that the sound in person is a lot better than what we see in Videos.

Is there a US distributor?
