ive got magnaflow mufflers with 04+ SE tips. I got them for $112 shipped from greyhound performance on EBay.

there is a vid on youtube of my soundclip. Search "modded grand prix gt magnaflow" or "grand prix gt magnaflow" and look for the vid that has the silver read end of my car with the GT emblem on the trunk.. i can post the link later if you cannot find it
