Looking to get the best bang for buck power out of your CLA or A45 AMG? Look no further!

Removing one of the most restrictive parts of the car, this downpipe kit provides a high quality performance solution for your AMG.

Newer 2021 design – Our CLA45/A45 downpipe design ensures a larger 3.5″ opening compared to the smaller 3″ design currently flooding the market, thus providing a better flow rate for your build.

This is a must for anyone looking at tuning their vehicle to a Stage 2.

Our downpipes are made from 1.6mm thick stainless steel piping, greatly reducing the risks of cracking, rasp and vibration.

Beware of inferior downpipes on the market made of thin pipe.

Fantastic brushed finish appearance.

Our downpipes have a larger opening from the entrance for a quicker turbo spool ensuring a sharper throttle response and much more agressive exhaust note.

Better relief of exhaust backpressure in comparison to the cheaper 3″ designs on the market.

Professional installation is recommended.

If you are looking for a complete Stage 2 setup to get the most out of the A45 & CLA45 series, then be sure to grab the Antz Performance billet 4″ intake kit to maximise your power gains.
