VRSF N55 4 inch Decat Downpipe - EWG F Series BMW M135i, M235i, M2, 335i, 435i
Unlock serious performance and sound from your BMW N55 with the VRSF 4 inch decat downpipe for EWG F Series models. This VRSF N55 downpipe is one of the best bang-for-buck upgrades for the F20 F21 M135i, F22 M235i, F87 M2 N55, F30 335i and F32 F33 435i. Expect reduced back pressure, faster turbo spool, noticeable power gains with a tune, and a deeper, more aggressive exhaust note. Built from premium SS304 stainless steel with smooth mandrel bends and CNC machined billet flanges, this is a robust, high-flow performance downpipe designed to last.
At Nforcd we have fitted and run VRSF N55 downpipes on our own cars and many customer builds. Fitment has been excellent and customer feedback on performance, sound and quality has been consistently positive.
Why choose the VRSF N55 4 inch decat downpipe
- 4 inch primary for maximum flow on EWG N55 F Series platforms
- SS304 stainless steel construction - hand crafted and TIG welded
- Mandrel bent tubing for smooth radius bends and reduced turbulence
- CNC precision machined SS304 flanges for a perfect seal
- Significant back pressure reduction for faster spool and sharper response
- Power gains typically 20 to 25 hp with a tune
- Richer, more aggressive exhaust tone while enhancing turbo sound
- Brushed stainless finish
- VRSF Lifetime Warranty on the downpipe
This VRSF N55 downpipe is available in catless decat race configuration as shown here, as well as a 200 cell high flow catted version for those who prefer a sport cat option.
Optional high temperature ceramic coating
We also offer Cerakote high temperature ceramic coating rated up to 1800 Fahrenheit. This thermal barrier helps keep exhaust heat in the pipe and out of the engine bay, which can help reduce intake air temps and lower overall engine and transmission oil temps. Note: while the downpipe itself includes a lifetime warranty, the ceramic coating carries a 1 year warranty, as do the catted versions.
