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.

MTC Motorsport BMW N54 135i 335i Stepped Front Mount Intercooler, also fits many other models

We have engineered these intercoolers using a bar and plate core matched to our flowed cast end tanks. This is the most efficient way to keep the intake temperatures low.

The MTC intercooler features massive 5″ competition core with flowed cast end tanks and increased the surface area

Ability to deal with over 600bhp

This intercooler provides near 100% more volume and 100% more surface area than the standard intercooler.

The intercooler is a direct fit and there are some great videos on YouTube to follow. However, professional installation is recommended and should take approximately 1-2 hours.

We have tested our intercoolers on a few vehicles and found they have absolutely fantastic results. The IAT compared to the standard intercooler are reduced massively which means you get consistent increased performance.

The standard intercooler and the MTC intercooler both had intercooler intake temperatures of between 135-140 degrees through 5 runs on the road.

At the other side of the intercooler into the engine the standard intercooler temps were between 75-80 degrees whereas the MTC intercooler temperatures were in the high 20’s over all 5 runs.

We would go as far as to say this is the best intercooler on the market for these models.

This product comes with a lifetime warranty.
