Modded 335i runs a 117mph/12.399 at track

That guy should have done downpipes. That’s where the real power is in the exhaust system. I’m doing one shortly with a custom tune.

From the reasearch I’ve done the Downpipes really only help if it is tuned. Procede V2 >>>>downpipes alone.

I can’t wait to see what you can get out this car with a tune. :tup:

X…

Sorry I meant downpipes instead of just cat back if you’re going to do one or the other.

im really starting to regret not getting a 335… oh well…

We need to talk sometime next week, if you don’t mind.
