Help Please: X-Pipe fit Question

What is the oustide and inside diameters of a stock 2001 pipe just after the cats?

Reason I ask, is that I purchased a used X-pipe that has the sleeve towards the cat which has an inside diameter of 2-3/4" and outside diameter of 2-7/8".

Will this work with the stock pipes coming from the cat?

What size TorcTite clamp will I need? http://www.verociousmotorsports.com/...-Exhaust-Clamp

Thanks very much in advance.

HI there,
It should work, and you purchase the clamps fitted for the OUTSIDE diameter of the pipe.

What is the outside diameter of the pipes coming from the cats on a 2001 C5 LS1?

Thanks very much.
