I'm pretty certain i'm gonna get the 05 GT next spring. One think that I want to do though is put a flowmaster exhaust system on the car. I'll have to see what the stock system sounds like but I really like the throaty sound that flowmaster has. My ? is will I have to get a whole new exhaust system? or can I just get the muffler that I like and get that installed. And if anyone has an idea how much a whole new flowmaster exhaust system is, it would be nice to know how much it'll cost. Thanks for any help.
