I have a 3" lanes true dual exhaust system sitting in my garage. they were on my 93 z28 with pacesetter longtubes. My question is: which set of ls1 longtubes are likely to work best with the least amount of fab work to get them to fit? do the ls1 and lt1 pacesetters have similar collector placement? I know Lanes true duals are a thing of the past but i aint sellin em and ive got this bone stock ls1 trans am im driving around so may as well throw them on until i go turbo again.

uggh its a tricky question..i guess a better one would be: do most of the long tube headers put the collector in roughly the same spot? Im assuming itll take fab work either way.

I cant see it being that different. Like you said it will take some fab work either way. The hanger placement is diferent as well iirc.

Yea thats what im thinking. may just sell them and get the on3 turbo kit, screw it.

The main difference is the driver side. On an LT1 both headers exit straight back and on LS1's the driver side header is kicked out about 10-15*.

The passenger side may need the length of the pipe modified to line up with the header and keep the rest of the exhaust in the correct position
