03 GT mufflers are nothing special, they're probably just like any other stock muffler out there. If you're not gonna run tailpipes at the end of those mufflers at least run turn down pipes so the exhaust goes to the ground and not on your axles
yea i am going to put turn downs on, but we just put a new catback system on my friends 03 gt and since i have no cash for some flows or somethng he gave me his mufflers
