What must be done to fit an LS1 catback on my LT1 car? Ive got pacesetter longtubes with an ORY. I am getting an awesomee deal on an LS1 exhaust and just need to know what I must do to get it to fit. Thanks

 

it will all bolt right up, the difference between the LS1 and LT1 exhaust is pretty much the y pipe and where the catback hooks up at. you will just need to get y pipe made at an exhaust shop prolly AT THE WORST but your y pipe will prolly work. does your y pipe collect close to the drive shaft? if so you will be good.

EDIT: correction it ALL wont bolt up.. it will all fit the car though and all the hangers are in the same spot.

 

I just have pacesetters y-pipe. It is close to the driveshaft, and the y-pipe ends right around the front of the driveshaft.
