Alright so after some pondering and wanting to put an X-Pipe on the GT I ran into a few issues that have me second guessing myself. I have some mufflers on here that are flowmasters which kind I do not know. I will have to look more into it this weekend, but just a few minutes ago I noticed that where the band clamp is above the axle the oem sticker for the mufflers is still there. I am so confused as to what the PO did to this before I got it. I still want to do an x-pipe but not sure if I am dealing with stock mufflers or the aftermarket, nor to say the less of how it will sound. I am amazingly knowledgeable about most stuff but this has my stumped tonight, maybe its all the school work and work lately and then adding this on top lol.. :uhh: any help or advice?
