People a person is asking for advice not a front row seat to a fight, Keep it on topic
As for your Question, i wouldn't recoment running 1 bar on a stock manifold too much heat retined by the block and too much exhaust trying to get through a hole it wasn't designed to go through, As for the stainless manifold they are pron to cracking Mine has cracked after 3 or 4 months but it did it's job when i wante it to, JAM manifolds don't remove the restricton in the third runner compleatly it only ups the tollerences,
your best bet would be to get one of the NEW WEPR Evo maniflods, But there are alot of other bits to get them running on a CT( like New Oil lines, Water lines and possibally a radiator), Other than that you could wait for Speedvision to get the mild steel ones in or Get one made up by your local Exhaust shop ( But that would Cost Mucho Denerio)
