Anyone put a second muffler on an rjc or gn1 4" single?
Louder or quieter than the muffler that comes with it? Honestly it being loud isn't the big issue it's the droneI run the BORLA XR-1 22" body 4" on my RJC system. A few slight mods and it fit great. It's a bit aggressive but so is the car. It's hard to have horsepower and keep it quiet.
