Re: What exhaust are you guys running with your swap?

Picked up some trailblazer SS manifolds for the 4x4 build I'm doing.


No dice.




The solution:
Planning to weld some pipe to these to get the outlets away from the frame, and then a couple of 2.5" V-bands to connect to the rest of the exhaust.

I found this out myself about a month ago, TBSS manifolds won't clear a 4l80.... Looks like headers are in my future.

Corvette or Cadillac would most likely work for you

5th generation Camaro manifolds exit straight down and fit the block pretty closely. I'd expect they'd work with a 4L80E, too. That's what I'm using, although I have a TH350.

I just cut the ears off the bellhousing. I do that on EVERY 4L80 I install. Makes routing stuff so much easier, and those ears are only used to hold on the dust cover, which I also don't install.

Yeah, I thought about cutting them off, but the cover is cast aluminum and really finishes off the underside of the transmission, so I don't really want to do that. I have a set of F body manifolds that will fit with very minor trimming of the frame, but I guess I'm really just looking for a good excuse to buy a set of high dollar headers.

What are you looking at for "high dollar" exhaust, besides stock is there any other cast aftermarket ones?
