E90 N55 335i Exhaust Help

GEE90 · 10-22-2020, 01:17 PM

Hi, I was wondering if anyone had any ideas or recommendations on what the best exhaust set up be to pair with catless downpipe? I have a 2011 335i XDrive with a catless downpipe. I am not looking to purchase a full exhaust but to modify the stock one from the cats back. So far I was looking into possibly muffler delete? or replacing muffler with Vibrant resonators. Was also thinking of swapping secondary cats with Vibrant resonators as another option. I'm really just looking for a deeper sound from the exhaust. What do you guys think would be the most bang for your buck option?

Thanks,

If you have catless DPS then just keep your secondaries in as well as the X-pipe. I'd just PE mod to the stock muffler.

I am running downpipes with a full customs 3' exhaust, but to awnser your question, thats a hard one, it comes down to what you like and want.

I removed all cats as well.

Unless your on a budget do not do PE mod , IMO its not worth it
