Will a LT1 Cat Back fit a LS1 ?

I have a Magaflow Cat Back, single cat. Anyone know what it will take to bolt up to my '00 Formula ?

You might have to trim off some extra tubing from the LT1 exhaust. The LS1 uses a slip fit that is a bit farther back then some LT1s, all you would need is to cut it to fit the LS1 Y-pipe and use a clamp of the correct size. Either a 2.5" or 3" would work.

If the pipe does not slip on, you could go down to the exhaust shop and have them expand the pipe for a slip fit. Real cheap and easy to weld up with the slip fit.
