Product Information
A valved exhaust in T304 stainless steel that replaces everything from the factory catalytic converters back, downpipes included. With the valves open, the exhaust flows through dual 3 in pipes for a measured gain of 9 hp and 16 lb-ft at the wheels; with them closed, a smaller path and a Helmholtz resonator keep it quieter when cruising. It ends in two RS-style oval diamond black tips with an APR logo.

How does the sound change with driving style?
- The rear mufflers are valve controlled, so the system is louder with the valves open under load and quieter with them closed, when the exhaust runs through a smaller 2.5 in path and the Helmholtz resonator.
Is it a bolt-on install?
- Yes. It installs with the included hangers, precision brackets and slip clamps.
