sweet thunder?
Same type of muffler, but flows better because it does not bottle neck down. It's also just as cheap as far as cost goes and will flow/sound great!
Just run it straight pipe, no muffer open header, Dont worry the SBC Sherrifs Dept. wont get mad.
So when are you gonna be done with your 10 Sec car Charles? I wanna run you with my Blue one. The Black one will be done in 2 weeks, once I'm done forging the motor. Oh yeah Desert Nationals are next Sat, so bring SOMETHING out this time, even if it has to be the girlfriends TA.
