N54 Exhaust Stainless Steel Catless Downpipe V2 For BMW 335i, 135i 2007-2010

  • Sale
  • Regular price $399.99


We are proud to introduce our 3″ Catless Downpipes for the N54 135i & 335i which now feature a cast stainless steel mouth. These 3″ downpipes are THE best bang for the buck mod available, with gains from 25hp & 30tq when tuned. By eliminating the restrictive catalytic converters in the factory downpipes, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.

Rather than necking down closer to the turbos like most of our competitors, our 3″ catless downpipe feaure a full 3″ design up to the 2.5″ flange which allows an increase of flow. Our 3″ downpipes are hand crafted from SS304 stainless steel.

Features:

  • Adds 20-25 HP to the wheels & 25-30 TQ to the wheels.
  • CAD/CAM designed cast bell mouth for seamless flange to pipe transition.
  • Hand made from mandrel bent, tig welded 3″ 304 grade stainless steel.
  • Smooth radius bends to decrease turbulence and increase flow.
  • Fits RHD and LHD models, a right angle o2 sensor adapter is required for installation on RHD models
