well... it all depends on how it's set up... if you have headers it will be MUCH louder than OEM manifolds... and if you have a cat, it will be really muffled,
so if you have headers, and NO cat (or a performance one).. you will get pretty loud when you rip on it... and it might even get a "little" annoying when you drive long distances on the highway... it will have a REALLY pretty growl though...
I have a 305... with a 3" I-pipe, with heddman headers and NO cat, with a flowmaster muffler, and if I ever get above 3000 RPM..., um, WOW (but when you drive "nice"... under 3000 RPM it has the sweetest GROWL, but stays "neighborhood worthy"
