We are proud to introduce our VRSF Catless Downpipe for your 2011+ BMW Z4 sDrive28i. This 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 downpipes are hand crafted from mandrel bent SS304 grade stainless steel and the turbo flange is precision CNC machined out of billet 304 grade stainless steel. All VRSF products include a lifetime warranty as well as our “No Hassle” satisfaction guarantee (including fitment).
- Made from hand crafted, tig welded 304 grade stainless steel.
- Smooth radius bends to decrease turbulence and increase flow.
- CNC SS304 Stainless Steel Flanges.
- Gains from 18-22hp with tune.
- VRSF Lifetime Warranty
