I have two ceramic coated SR20 exhuast manifolds that were used on my car and removed for various reasons.
These are generic bottom mount T2 flanges manifolds that were run on my cars mated to a GT2871R .64
–
One is the manifold that Dan (U2nDyno) had an external wastegate welded to that cracked… i had it welded up and ran it for about 1.5 years on my car… coated at fireball coatings.
i took it off this year because it cracked around the base of the turbo flange… this was partly due to the fact that it has already been rewelded from where the EXT WG tube dan had put on cracked off.
–
The other is the exact same piece, uncracked… the reason i took it off is because when i sent my turbo back to Precision to be resealed i found that one of the holes in the turbo flange was stripped and i couldnt put the stud back in… rather than have it redone i simply put on another manifold… Dan’s one… This manifold was coated at Fireball with Dan’s…

Both are sitting in my garage right now.
cracked one: $old
stripped one: $75
