VRSF N55 3.5" Catless De-Cat Turbo Downpipe/Front Pipe SS304 (PWG up to 07/2013) BMW F10 F11 535i/535xi, F07 535i GT, F12 F13 640i, E70 X5 35i, E71 X6 35i - High Flow Race Straight Pipe Stage 2

Unlock serious flow and a sharper exhaust note with this 3.5 inch stainless race de-cat front pipe for BMW N55 PWG engines built up to July 2013. A true bolt-on turbo outlet upgrade, it replaces the restrictive factory catalyst to reduce back pressure, sharpen throttle response and let your turbo spool faster. Ideal for drivers chasing more mid-range punch, stronger top end and a more purposeful soundtrack from their 3.0 turbo straight-six.

Crafted from premium SS304 stainless and expertly TIG welded with smooth mandrel bends, this free-flow race pipe delivers reliability, precision fitment and excellent durability. Paired with a suitable remap, typical gains of 25–30 bhp are achievable thanks to the improved exhaust flow. Backed by VRSF’s Lifetime Warranty and No Hassle fitment guarantee for total confidence.

We run and install these systems at MJ Modifications and our customers consistently report quicker spool, crisper response and a deeper, more aggressive tone. If you want a proven N55 PWG exhaust upgrade that fits right and performs, this is the one.
