MTC Motorsport BMW 135i 335i Stainless Steel Decat Downpipes

  • The BMW 335i downpipes are machined from T304 high-grade stainless steel and are tig welded in house
  • The decats are fabricated in the UK and the flanges are laser cut between 10-12mm
  • Sharper throttle response due to faster spool of the turbo
  • Noticeable power gains and a much more aggressive exhaust note which sounds truly amazing
  • Produces lower temperatures and less exhaust backpressure due to the relief of the turbocharger. Also, the cylinder charge is increased
  • There is also a substantial weight saving in comparison to the factory catalytic converter
  • Made from one piece of stainless steel using a 12-axis CNC tube bending machine for better gas flow and maximum internal size to ensure ultimate performance without the loss of mid-range torque.

These downpipes will fit the following models:

  • BMW 1 Series E82 E88 - 135i N54 Engine 2006-2010
  • BMW 3 Series E90 E91 E92 E93 - 335i N54 Engine 2006-2010

We have tested this product and found increases of 12-17bhp.

Professional installation is recommended as some exhausts sit slightly different from others and can be tight.

We also recommend purchasing a Lambda Sensor Spacer(s) to prevent the engine light coming on in most cases. If you search our other items you will find these. 

This product comes with lifetime warranty.
