Just picked up a set of what I now know to be mufflers from Magnaflow's truedual kit at a swap meet. The kid swore up and down that these were for a GT and would fit just fine however I now have my doubts. So did I get stuck with a pair of mufflers that wont fit my car (06 GT)? If so, any market for just the mufflers (just looking to get the $150 I paid for them out of it)? Thanks for the help!
