6.1 aftermarket exhaust - No Drone Wanted! - 04/25/15 01:40 AM
Question - and Im sure its been bounced around here before - which 6.1 aftermarket cat back exhaust has the least exhaust drone and best power gains? I had the SLP Loudmouth on a 5.7 Magnum and the drone at 2200 rpm wasn't worth the minimal (if any) power gain. Borla? Corsa? Pypes?
