Pypes pype bombs vs slp loudmouth axle back exhaust system for 2008 mustang GT

[XRAV]

I have recently bought the car fully stock and am planning to add one of these two aftermarket exhaust systems, because the stock exhaust is very quiet. I plan to keep everything else as is, and was wondering which has lower drone, and produces an overall better sound quality.

The best muffler for what you are after is Borla/Ford Racing Stingers.
