If you're looking for a performance exhaust providing a mellow sound, lightweight, easy to install, increases horsepower, and lack the low rpm "drone", this is it!

We have extended our line of Active Autowerke stainless catback systems to include the latest generations of street specific performance exhausts. Active's exhaust systems are known for their drone-less, mellow tones, excellent fitment, lightweight, and subtle yet attractive looks. All Active systems are dyno-tested for real performance gains. Exhaust systems feature larger than stock double walled tips with embossed logos to fill your existing bumper ports, mandrel bent tubing, mirror finish tubing and canisters, and higher flow rates compared to the factory exhaust.

Limited Lifetime warranty plus a two year warranty against defects in workmanship and materials.
