QTP 2015+ Dodge Challenger Hellcat Screamer Exhaust System
A dual mode muffler with a single inlet to a dual outlet. One outlet is a straight pipe with a valve at the end. When the valve is open you get the loud and free flowing exhaust system. Close the valve and the exhaust gases are diverted through the muffled section to get the quiet mild manner sound. The Screamer is the only exhaust system that you can control from the driver seat. Go from Quiet to Riot in seconds.
