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.
MTC Motorsport High Flow Intake Hose Kit for N54 BMW 135i and 335i
This kit is for the standard turbos which have a 45mm measurement on the turbos. If you have hybrid turbos measuring 50mm please see our other products.
This kit keeps the OEM location and makes a huge difference to the standard restrictive intake system.

The intakes are made from silicone, reinforced with metal wire inside for maximum strength
Our hoses are also fluoro-lined to prevent discolouration
This hose removes all the restrictions caused by the standard pipe has and has a much smoother flow into the turbo. It is a must have for those extra performance gains
The high flow intakes are one of the best modifications with gains of around 60bhp just with the intakes alone

Included in the kit:

x2 Reinforced Intake Hoses
x2 RamAir Filters
x2 57mm Alloy Joiners
x2 25mm Alloy Joiners

Professional installation is recommended as these can be tricky to fit due to the N54 engine being tight to get to.
