We are proud to introduce our Yahua race downpipe for your BMW 535i & 640i with the N55 engine.

This direct bolt-on high flow downpipe is THE best bang for the buck mod available. By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note. Our race downpipes feature a full 3.5¡å stainless steel design and are handcrafted from SS304 grade stainless steel. They also include a lifetime warranty as well as our ¡°No Hassle¡± satisfaction guarantee (includes fitment).

In order to guarantee fitment, we highly recommend that customers send a picture of their downpipe from the engine bay in order to verify fitment.
