66 exhaust suggestions ??
 

im putting in a SBC backed buy a TH400 into my 66 GMC with long tube headers and was wondering if anyone had any suggestions about a y pipe.

I was wondering if a slip fit ory pipe for an ls long tube header system would be able to clear under the transmission if not ill have to figure out another way to run my exhaust. I want to run the y pipe and a black widow muffler and exit the pass side in front of the rear tire any suggestions ???

you want to combine both banks?

Not a bad idea. Run smaller pipe for each side into a larger pipe dumping out in front of the rear tire.

Yes just like any of the new ls motors they all run a y pipe but they all cross under the trans I was wondering if one of the ory from a ls truck kit would go low enough on the cross over to clear the Th400 I'm going to be running
