n51 catless advice!!

crisis1231 · 03-20-2020, 04:32 PM

Hello all!
I tried searching the forums and online and could not find an answer.

I just picked up a 2010 e90 328xi N51 6 speed manual

I want to ideally run a fully catless exhaust and cannot find the right pipes.

Does this have to be custom-made or can anyone recommend any catless pipes that will exactly match the exhaust system on this?

Ideally I want to get something plug and play so I can revert back to the stock system easily when necessary.
Please advise and thanks!!

Im thinking I will gain 20-30hp if I remove all cats and replace with headers and catless midpipe.

Thank you! I am working on finding catless midpipes as well. Found supersprint midpipes at decent prices.

Any other recommendations for midpipe?
