The Mercedes 45 AMG platform is quite impressive with it's 2.0L turbocharged engine. Like most turbocharged vehicles, the exhaust system is one of the first upgrades to really gain power and performance. The catback exhaust on the 45 AMG platform is designed quite well and has a great noise to it under load. But the cars downpipe is really where the power can be gained. To meet federal and state regulations, manufactures must create exhausts parts that meet emissions and sound requirements. With this, the AMG 45 vehicle has a restrictive catalytic converter on the downpipe.

To improve the vehicles performance, Agency Power manufactures a high flow cat downpipe for the Mercedes A45, CLA45, GLA45 vehicles. The factory downpipe is flattened where our aftermarket one stays tubular to give the best exhaust flow possible. Designed to mate up to the stock catback, it can also be used with other OEM style fitting exhausts. As tested on our CLA45, the upgraded highflow cat downpipe greatly increased low end torque and mid to top end horsepower. The turbos spooled much more quickly and they added a slightly more aggressive sound to the vehicle.
