Hey guys,
So far we have confirmation that the following products WILL fit the 135i :headbang::
Metal Substrate High-Flow Catted Downpipes
Catless Downpipes
Both versions feature 304 stainless steel piping, machined flanges, o2 sensor bungs, and of course...our guarantee of fitment. Each piece, is hand made in-house, and TIG welded to perfection. Using cast (not mandrel) 304 stainless steel elbows allows us to maintain a 100% uniform diameter throughout the entire product (as opposed to crush bends, or some mandrel bends that have wrinkles left behind).
Three dyno charts. For comparison purposes, these were all performed with the stock catback exhaust installed.
