Flowmaster

Had flowmaster 40 series with headers on 2 1/4 exhaust. Originally, the exhaust went all the way to the rear bumper. Sound was nice, didn't really notice any drone. One day I decided to cut the tail pipes off, so the exhaust was basically dumped right behind the muffler. Much louder and deeper sound at idle (muscle car sound), and very aggressive sounding when opening up the throttle. However, there was an incredible amount of drone with this setup. I eventually reattached the tailpipes before selling the car. So, if you're looking for a muscle car sound at idle and wot, my setup fit the bill.
