I recently went the muffler delete route after running the golf tee mod on my e93 335i for a year. Worth all $180 I spent to get them cut out and adding 4' tips. My neighbor has a 335is with BMW PE and I like the sound of my exhaust much more now.

Alright guys got a question for you... I'm gonna be doing this soon and trying to figure it out. Right now I have stock E90 Exhaust with a secondary cat delete. My concern is the secondary cat delete and it sounding like shit. I know I need an x-pipe to replace the resonator but should I get rid of the secondary cat delete and put vibrant resonators or something there so it doesn't rasp?
Edit: Basically what i'm asking is if anyone has done the recommended setup (x-pipe for e90, outer pipes replaced) with a secondary cat delete? I hate rasp so would hate to do all of it then have to throw in resonators or something because it's too raspy

I think i'm gonna order vibrant resonators and see how it sounds with that. Hopefully it gets rid of the rasp and makes it a smooth good tone

this one would seem similar to what you would be doing. kind of hard to judge in his video though Quote:
this one is with res in place but also has cats to, so i don't think it'll sound the same as your would without cats. if anything you could try leaving the res in and if it doesn't sound good make modifications afterwards |

No. But think about it. How could it be? You've replaced the perforated pipe that was on the passenger side with a solid pipe. So all the exhaust gas is now flowing out a solid pipe on cold starts.

The replaced perforated section is after the pipe that connects the two mufflers so it will still flow through to the other side a bit. It's not completely blocked of. The flap is on the driver side and when its closed it would still flow through to the pass side. It will quiet it down a little bit but not as much to be oem like before mod. |

Nope, haven't put my hand behind the exhaust but with the flap closed on cold start you can see all the exhaust going out the pass side and not the drivers side. Even with both sides modded it should still have the same effect and quiet the tone down it just won't quiet it down as much to normal non modes tones

to save me reading 68 pages and because some of the links no longer work:
1. did anyone open up a PE exhaust, if so what did they find? 2. did we agree on a method to make the OEM one sound like a PE? 3. what do I need to do for my 2007 335i M Sport to make it work? 4. did anyone find someone in the UK to do this and found it doesnt just give off a rubbish sound? Thanks Dave |
