Ok, here are the manifolds in order:
HKS $850, and from what their website says, its made from sus304 stainless steel. The website said it's constructed of 304 SS, I have heard nothing bad from this manifold via searching.
SP-Power.com, $350 - made from 304 stainless, from all the reviews I read people posted about cracking, a "possible" solution is to have more welding done, add brackets so there is some support for the weight of the turbo, and the motor movement, and add a flexpipe on the downpipe to reduce stress.
JIC $ 650-700, not sure what its' constructed from, their website says stainless steel "derr, I thought it was cf!!", upon researching the manifold, found out a couple cases of cracking. Here are some pics of the bottom, side, and top views.
JGYcustoms.com, $300-400, the site didn't say whats its constructed from and I couldn't find anyone that posted online any experience from this manifold.
Uras manifold, $499, this is "mr. drift monkey" company, I have yet to read a post about this manifold, and it must be bought from JDM land.
ProjectSivlia.com, $399, have seen posts about this cracking, and looks similar to the sp-power manifold. 304 SS construction.
TurboCalculator.com, $399, haven't read any posts about it, and I wish they posted better pics of possibly the welds on their site.
And here is the round up of the generic manifolds that run between $150-300 bucks.
Enjukuracing.com manifold, $299, peeps have been saying that this is the same exact manifold that obx makes.
ok, so there is the list for stock replacement, t2 flanged bottom mounted manifolds. There are debates about 304 SS and 321 SS, but all arguments point to the welding.
