Are these worth it if you don't change any other exhaust component? Is the muffler a bottleneck in the exhaust system? Will the msp muffler add performance or is it just for a nicer exhaust sound?
the muffler's just for sound. unless you replace the piping, you won't see any gains. the msp muffler's ok i guess. i drive an msp.....it's too quiet. can't hear a damn thing and the piping is really small too. go aftermarket definitely.
