Hello All- I Bought a new 09 Silverado Saturday, 4.8 LS. I am only doing two mods: K&N Panel Filter and a muffler swap; the question is, "what muffler?" My previous vehicle was an '04 GTO with intake, mids, CB, tune...I had a FM CB...I don't know if I want a FM on the Silverado though. I am keeping Single In and Single Out, that being said...no glasspacks or straight pipe, I don't want a choppy or popping sound, so... Corsa? Bassani? Magnaflow? Other? Thank you for any thoughts or opinions offered!
