Now that your BMW E92 M3 has a new exhaust system on it, you are still itching to get more power and a more aggressive sound. Well Agency Power has developed these Section 1 and 2 pipes to give you a complete header back race exhaust system. The all T304 stainless steel pipes feature TIG welding, thick flanges, 02 Bungs, gaskets, and a complete polished finish. The OEM replacement pipes delete both the catalytic converters as well as the center resonators for a full race system. These pipes in conjunction with our Agency Power muffler and a software tune will yield a 30 horsepower gain. The Section 2 and Cat Delete Pipes are sold as a pair for the BMW E92 M3 coupe only.
