We installed the Borla Challenger SRT8 Exhaust on a 2010 Challenger over the weekend. No drone, at idle it sounds a little deeper than stock. Sounds really awesome on the car and under acceleration. Entire system came off and new ine installed in less the 90 mins.

Thought everyone might enjoy the before and after video....
