MTC Motorsport BMW 135i 335i Stainless Steel Decat Downpipes
The BMW 135i 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.
