I saw these on a GT at the Garlit's show in Ocala this past weekend, which no-one came too that I knew! :P This woman was from Tampa and some guy took OE Corvette sidepipes and made them functional.The sound was about as it is now on the stock GT, but she said he added a lot of baffles.They're attached right behind the turbo from the looks of it. The length seems to be just right for the car, and I was thinking maybe the same thing but either painted to match or powder coated.
