Do xi downpipes fit regular rwd models?

Jimmy335xi · 09-13-2014, 11:55 AM

I know the regular downpipes won't fit to an xi models but what about the opposite? Cuz i have xi catless downpipes on my car and my friend wants them on his 135i was wondering if it would fit.

No they wont fit. Different dimensions when they flow down due to xi subframe.

AFAIK the only difference between them is that the xi DPs neck down from 3" to 2.5" early to allow the extra clearance needed on the xi. The path is definitely the same so I expect they would fit without issue.

They will fit, they just arent as free flowing as an non xdrive, but if its a basic bolt on car, you really shouldnt see a difference in power.

They will fit for sure because riss race downpipes work for both I/XI... At the end of the day we have the same turbos and dp back exhaust... So you can do the math, its just a front diff that the I's don't have

Have an xDrive, they definitely will not fit. sub-frame in the way.

I think you read it backwards mate. Hes asking if xdrive downpipes will fit a non xdrive. Not if non xdrive pipe will fit an xdrive.
