I had a set of Flowmasters put on my 06 GT and made the huge mistake of not keeping the originals. The flowmasters sound awesome going through the gears, but to me are a little annoying at cruising speed. I am basically hoping to find someone that is wanting flowmasters and is wanting to trade me their factory mufflers for the flowmasters. I am in Raleigh, NC 919-255-2469
