    I need a quiet exhaust!!

    I just finished a heads/cam swap and now my exhaust is just way too loud. I have a SLP cat back and Pacesetter long tubes with ORY. I'd like to keep the headers and Y, but I want a really quiet cat-back with a nice deep tone. I've been over to LS1Sounds, but it's not really giving me a good idea of how loud the exhaust actually is. What do you guys think?

    How quiet? Like factory quiet? Or do you want quiet idle and louder @ WOT?

    Im not looking for stock sounding, I don't even see that being an option with my mods. I would like quiet at idle and loud at WOT but I need somthing much quieter than I have. As far as loudness Id like the same volume as a car with a catback but stock manifolds, if that makes sense.

    SLP Loudmouth? Those are going to be very loud after cam/headers. A Magnaflow would tame it down alot, and put a nice deep tone that screams at WOT.
