Ok. So let me explain my situation. I've installed my BMW PE a few months back, and I'm not as impressed as I thought I would be...
Car is an e92 335i 07, it has AR catless DPs , and the PE ... With stock mid pipes .. At start up /idle it sounds beautiful...All the way up to about 3-4k rpm. Everything after that sounds raspy and quite honestly nasty. Like a civic almost

What can I do to solve this

I've been told add 2 resonators.
But , Will this take away from the start up noise and everything before 3k rpm ?

Also. Which resonators do you guys recommend ? And what about placement ?


I've also heard change the mid pipes... To even put the OEM DPs back in ( not an option )






Any sound clips would b great

Same situation here but with the 'is' exhaust.
After the vrsf down pipes I hate how raspy it is.

Also considered putting OEM DP back in, not an option.

Problem with taking mid-cats out and installing resonators may be smoke and smell will increase.

Highly considering now the cp-e or AR Design catted or resonated down-pipes.

I hope more post on this topic.

I was thinking putting the resonators a little bit down from the DPs. But I was waiting to see if I would have gotten some responses here. See what others have done .... No help anyone ?

335is here as well and it is a little raspy after 4.5k with catless DPs. It's certainly not a deal breaker though.

I agree it's not. Just don't like the ricey sound. Think I might as well just remove the 2ndary cats and add resonators Didn't want to have to do that. But guess there's. No other option

U guys are upgrading your exhaust and then complaining about the sound?

i had the PE For a while. I honestly think its the best sounding exhaust with stock downpipes. after installing AR downpipes it sounded like shit IMO. on cold start it sounded like a boat and under load it sounded like a semi tractor trailer hitting vtec. if you start messing around with adding resonators you will lose a lot of the very characteristic burbles/pops. honestly the best thing you can do if you don't want to get rid of downpipes and lose power to improve the sound is go back to a stock axelback. you will lose most of the harshness and rasp. IMO the remus exhaust sounds better than any exhaust with downpipes. I have a bunch of clips of cold starts/drive by/gopro ext mic/ footage of PE with and without downpipes and Remus with downpipes. So yea tl;dr if you want to keep downpipes and have an exhaust that doesn't sound like shit, ditch the PE and get a remus or stock.

Really ?

I have Catless DP's they are 2.5" not 3" and my car sounds GREAT...

specially when I get on it... now I did connect the Valve back so my second muffler stays closed most of the time at normal driving conditions..

I think I figured it out. I really have a problem when the top is down. With the top up I do not have a problem with it as much. Actually I do like the WOT sound.

I have been contemplating on getting the new Cobb Catted down-pipes. But now I question would it really make that much of a difference in the first place. Or would adding resonators be a better option. I think the cleaner option is the Down-pipes. Does anyone think the catted down-pipe with the 200 CEL cats will rid the raspiness?
