got a 01 grand prix GT. i know...most of u are going to tell me to just get a whole new exhaust system...but i don't see the sense of doing it just for a deeper sound and no added hp..i'm fine with the sound of the stock exhaust... i just want a different appearance. i'm planning on going with some dual chrome tips from autozone. how do i install them? i just got from under my car and i see there is a clamp that seems to hold the tip to the muffler... there appears to be bolt holding it there. after about a hour, some wd40 type stuff from autozone and the help of my handy 15mm Wrench i've gotten the 10 year rusted bolts loose on both sides...but the tip still won't budge....someone please help. i'd like to get this done soon...also i've never posted pics of my car...so i'll go outside now and do that....hopefully when i get back and upload pics i'll have a few replys..
