Mercedes A45s Downpipe With 200 Cell Hi-flow Sports Cats & Heat Shield 18

MTC Motorsport Mercedes A45s Stainless Steel Downpipe With Hi-Flow 200 Cell Sports Cat and Heat Shield. The A45S W177 downpipe is machined from T-304 high-grade stainless steel and are tig welded in house. Our downpipes come straight from the turbo providing a sharper throttle response due to a faster spool of the turbo.

This will provide noticeable power gains and a much more aggressive exhaust note which sounds amazing. This will produce lower temperatures and less exhaust backpressure due to the relief of the turbocharger. The cylinder charge is increased which gives you maximum performance. This will fit the following models. Mercedes A45s, CLA45s and GLA45s 2018.

We have tested this product and found increases of around 20-25bhp without tuning and 80-100bhp on a tuned car. Professional installation is recommended as some exhausts sit slightly different from others and can be tight. These should pass an MOT emissions test when fitted.

It is road legal and Euro 5 rated. OPF may need to be coded out, worth speaking to a tuner before hand to check this with your car.
