The factory exhaust system on the W177 provides a signature AMG bark, but the standard catalytic converters and petrol particulate filters heavily restrict gas velocity and limit top-end horsepower. Reclaim the true aggressive tone of your turbocharged four-cylinder by swapping out the restrictive factory piping for high-flow Exhaust Downpipes, drastically reducing turbo backpressure and accelerating spool times. Transform the acoustic presence of your hyper-hatch with a premium Cat-Back Exhausts system, and explore our complete selection of Misc Exhaust Parts to achieve the perfect custom fitment and motorsport-inspired sound.
