Turbo Headers/Manifolds

Hey everyone,

Haven't been on here in forever. I'm selling my TA and am planning on putting twins on the IROC. Only problem is I HATE the look of the truck manifolds pointing up...looks god awful in my mind.

SO...post pics of what you guys are using as headers/manifolds for your front mount turbo builds! I was wondering if the stainless works up and forward headers would look decent or not.

Thanks!

Re: Turbo Headers/Manifolds

So it seems like the only way to do it is to fab your own? /

Or do you think these will clear everything even the power steering?

Hard to say without trying...BUT. I wouldn't choose those headers for other reasons...the primary and collectors are WAY too big. Spoolup would absolutely suck.

Re: Turbo Headers/Manifolds

Not sure on the accessories but the stainless works ones would work, for most builds. Depends tho, you may need to do what fireball did, angle them to the outer battery trays. Thats same way i did mine but mine is a sbc.

If you want functionality you can buy prefabbed headers or manifolds and work with them. If you want looks, go custom made and set them up how you want them
