By installing our Circuit Werks High Performance exhaust system, you will not only improve dramatically the sound of your BMW, but you will also gain the horsepower where you would normally drive the car. Like to a local car meet, to work, or weekend cruising around town. The sound is very subtle but once you step on it, you can hear the deep sport tune exhaust tone. Deep tone at low RPM, and a true performance V10 scream at high RPM. Depending on your mods, but our exhaust will easily get you 12 to15+ hp to the wheels. High polished stainless steel, all are hand built to meet our high quality standard, then T.I.G. welded together. The Black Edition Tips are High Temperature Coated.
