The ultimate driving machine now sounds like a true sports car. Agency Power has taken the E92 BMW M3 V8 engine and given it a sound boost. The Agency Power exhaust has a great tone which gives your car the race sound many desire. The AP exhaust system has been engineered and dyno tested to not only improve the sound, but gain horsepower and improve top end performance. After months of testing, AP completed the beautiful dual muffler design. The all T304 stainless steel exhaust is TIG welded and polished to a mirror finish. The exhaust uses the existing hangers for a secure rattle and clearance free fit. To stand out amongst the rest, the system features quad 2.75 inch titanium tips with a titanium burn finish for an exotic look. This muffler section also includes S pipes to make a complete bolt on exhaust system. As tested on AP's Mustang dyno, the exhaust gained power throughout the RPM band. The peak gain was 5hp and 3ft/lbs of torque however with a software upgrade this exhaust can reach 30hp and 20ft/lbs of torque (as proven on the dyno). A great addition to an already well tuned factory car, this exhaust is designed to fit the E92 M3 coupe and cabriolet only.
