Header reducers


I have the Corvette Central dual exhaust system on my '80 'vette, it's a 2 1/2" system, with block-hugger headers. I want to install a set of full length headers. Can anybody point me at a set of header reducers that will slip over my existing exhaust pipes so I can just saw them off to the right length and use a couple of exhaust clamps instead of welding them on? Thanks a bunch, see ya,
Scott
