85-88 Tubular Exhaust Manifolds
« on: April 11, 2010, 12:59:13 am »
Can anyone give me any information on those tubular exhaust manifolds that GM used to put on truck 350s? I got a pair and it looks like they flow really well considering that they have a 2.5 inch collector(flow well after you remove all the smog stuff). Stainless too, I think. Can't find info anywhere on these things. A good choice? Thanks! 8)

I have never used them, so I can't say one way or another.

I dont remember what they look like, but I would guess they resemble short tube headers? If so, they should flow just fine, much better than manifolds.
