someone is willing to sell me a borla catback with everything included for a reasonable price, however it is off a 1998 trans am with an ls1...is it going to sound like **** since the muffler is tuned or shaped to sound for an ls1? and will the catback still be able to bolt right up, or are the ls1 exhausts located in differently then ours??

 

you will need an install kit from slp or have an exhaust shop make you an s pipe to make it fit
