273 Y-pipe?

The Accurate unit is a nicely engineered well made y collector piece. Another cost effective option is to just purchase the accurate y pipe and fabricate or have shop fabricate the rest of system to your taste. Also common to run without expensive resonator. Gibson has a tip that is almost identical in dimension to original chrome tip on resonator. Just cut straight pipe to length of resonator & add tip. Fills the original rear cut out for that famous look & no one will no unless they look under car.

This one?
I remember a few years(2000?) someone was making resonator tips. If the gibson one is close, I can just cut the back off of their tip.

All I need is the Y-pipe, muffler, axle loop and resonator.
