That's a nice sounding muffler but it is big and attracts police attention! My friend had one on his Spec V and took it off 2 weeks after installing because of cops
I have stock piping until the cat, then 2'' into a resonator and then a 2.5'' Ansa silverline muffler. My car is a 1.8 so I didn't do the setup for any valuable gains. It sounds nice with my intake, though.
What's up man, another Sentra driver? I recognize the car in your avatar from the B15U forums; I know it's not yours, but curious as to what you're driving!!! Take care man
