VRSF 3.5" Ceramic Coated Downpipe N55 10-13 BMW 135i/335i/X1

  • $289.99


We are proud to introduce our VRSF 3.5" catless and catted downpipe for your N55 135i & 335i/xi. Thie 3.5" 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 catless downpipe feature a full 3.5" stainless steel design as well as a cast 304 grade stainless steel merger that offer a smooth transition from the turbo to the mid pipes. All VRSF downpipes are hand crafted from SS304 grade stainless steel and include a lifetime warranty as well as our "No Hassle" satisfaction guarantee which includes fitment. Each kit includes heavy duty, grade 12 bolts, nuts and washers along with two mid pipe gaskets. We also offer additional installation accessories such as the turbo to downpipe clamp and gasket. The turbo to downpipe clamp and gasket aren't required for installation but are highly recommended if your original accessories have more than 50-60k miles.
Ceramic Coating: 
Our N55 downpipe now comes ceramic coated free of charge. We use Cerakote's best thermal barrier coating which helps keep the hot air inside the exhaust and out of the engine bay which decreases overall intake air temps along with engine coolant and transmission oil temps.
Note: We now offer a catted option which features a Magnaflow 200 Cell Count High Flow Catalytic Converter.
