Product Information
This is a stainless steel axle-back exhaust that replaces the factory system from the rear axle back, finished with twin 89 mm ceramic black tips. Lower back pressure is rated to add 6 hp and 5 lb-ft at 6,600 rpm, and the sound turns louder and sportier under hard acceleration while a Helmholtz chamber keeps low-rpm drone down. The factory computer-controlled exhaust valve is eliminated with this system.

Will it drone on the highway?
- A Helmholtz chamber in the system reduces resonance, or drone, at low rpm. The tone stays civilized at light throttle and turns more aggressive, with added burbles and pops, under hard acceleration.
