I got a set of Mac Midlengths used years ago and they didnt come with a
y-pipe. My question is which Y-pipes will work and where can I buy them. Thanks. Its for a 93 Trans Am LT1.

The only y-pipe that will bolt up without fitment and alignment problems is the MAC y-pipe.

I have 1 more ? I forgot to ask, is there a gasket that goes in between the Y-pipe and headers where they bolt up? Like a collector or donut gasket? I ordered my MAC Y-pipe and completely forgot to ask.

Nope, They just bolt up man. The copper gaskets they will send you with them are really nice too. Never had any leaks with them.

i found it cheaper (for me) just to have the y pipe custom made

You mean the header gaskets they send you? It seems a little weird that theres no collector gasket. Yeah I paid $180 shipped for the Y-pipe and 4 studs I needed. Its a little high but I though an exhaust shop would have charged more than that to make one.

Yes, the header gaskets they send you are great quality. As far as the y-pipe goes, they sent me the y-pipe along w/ some clamps to mount them up. I never ran any sort of gaskets with my old set up.

Take a look at the link here. http://www.macperformance.com/store/...Product_ID=457 This is how they clamp together.

just get longtubes

There already on Im not taking them off now. I love my Mac mids. They look very well made with thick flanges and Ive heard there just as good as longtubes. Plus the plug access is great.

Agreed. They were my first set of headers. Plug access was awesome and fit was real good.
