I need a new Y-pipe since I got new headers, and my old y-pipe doesn't fit. The new headers are 1 3/4 x 3 Pacesetters. Does anyone make ones already made like the one Pat G made with the 3" to 4" merge:

cut your old Y-pipe in 1 or 2 places and adapt it with the right tubing.flow master makes a 4"to3" merge pipe.do you have a welder?

Your best bet would be to have it custom fabbed, which is clearly what he had done. The merge he used, if I'm not mistaken, is made by Burns stainless, but was an LG Motorsports spec'd design that he ordered through them.

Hmm, what do you all think of QTP's design?!:

"LS1 Y Pipes
Piping Merges to a 3"- 4" Flowmaster Y Collector Reduced Down to 3" to Fit 3", 3.5" or 4" Catbacks. All of our Y Pipes are built with the Flowmaster Scavenger Series "Y" Collector. Why make quality header and then just slap together a y pipe. Unlike other systems that slams the two pipes together ours uses the Flowmaster Y Collector help the exhaust pulses flow without any loss of velocity."
