B58 True 4.5" Catless Downpipe

*Fits all Gen 1 and Gen2 B58s (and supra)*

Introducing the BimmerNetwork B58 High Flow Catless downpipe.

This is a TRUE 4.5inch all the way until the exhaust meets the dp. This will bolt on to your oem exhaust(no modification needed), or can be cut at the taper and welded to a true custom upgraded exhaust, with the addition of a larger diameter flex joint, this is a real high flowing downpipe that will reduce backpressure and relieve stress off the turbo. Unlike others on the market that are 4.5 at the turbo outlet and taper significantly right after the turbo.
