So I don't know if anyone has stumbled upon this but ATP Turbo has a T3 Turbo Merge Y-Pipe for the Tiburon GT's gee go figure. Now it looks like custom making piping has become a little less stressful.

Specs:
T3 flanged turbo merge pipe (y-pipe) for 2003 and newer Tiburon GT 2.7L engine. Allows T3 flanged turbo to be easily mounted to this engine. Testing on T3/60-1 turbo with 100% engine and factory stock cats into this merge pipe at 5psi makes over 300WHP (350 crank HP) with a free flowing exhaust system. Pipe is flanged for Tial 44mm V-Band wastegate.
Do note the bolded area :3_yes:
