We are proud to introduce our VRSF 3.5" downpipe for your N55 F10/F11/F07 535i & 535xi, F12/F13 640i Coupe & Convertible, E70 X5 35iX & E71 X6 35iX (full application list below).
This direct bolt-on 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 downpipes feature a full 3.5" 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).
Please note that there is no exact year designation for 3.5" or 4" models across the board. We highly recommend that customers include the last 7 of their VIN in order to help us ensure you have selected the correct size for your vehicle. While we can assist with helping customers chose the correct size, it is the customer's responsibility to make sure they order the correct size.
