I should have expanded. I think if you have over 50k miles yer ok to do
this. I guess I was thinkin' about the truck specifically. What I'll
probably do is use 45 and 90 degree bends to fab up a Y-pipe and then have
it welded up. It'll have to have a bung welded in for the O2 sensor. I'd
venture there is 15 hp to be found in the exhaust between the converter and
manifolds.
