Downpipe
Im looking to go from stage 1 BM3 to stage 2. Wondering if anyone has suggestions for a catted downpipe that fits a 2014 335i gt f34/n55. Thanks.

I'm looking into the same thing this weekend. If you don't mind, perhaps this thread can also cover a few other areas of air movement, if only because they are all interconnected.
I've done nothing to my GT but a VRSF charge pipe after mine broke a year ago. I'm considering going back to VRSF for the down pipe. I'm wondering what I'd expect if I also changed out the turbo inlet, intercooler, and exhaust. I see many suppliers making two different sizes of intercoolers, would it effect turbo lag if I increased the volume, or does the twin scroll account for that, or does it require a remap, via BM3 or the like. 2015 335 GT, myself. |
Appreciate
