This manifold just became available to the market within the past 6 weeks or so. I figured I'd show it off a bit in case someone else is in the market for one.

It's a bottom mount true-divided T4. Twin-gated, forged stainless construction, .109" wall thickness tubing, etc....

This thing is awesome. Fit's like a glove and the craftsmanship is superb.

For more info, check out Jake's website: http://www.jhracing.net/Twin_Scroll_T4.html

These are also on sale right now at $200 off of the normal retail price!

Punishment Racing, Straight Line Specialties, and Shearer all come with a lifetime warranty.
 
Thanks for the info, guys.

I guess the warranty thing isn't very important to me. Properly crafted products have a lesser rate of failure, and even so - there's a TIG welded in every town these days. My cup is half full. I anticipate it to perform, not fail. To each his own though.

even the highest levels of craftsmanship in exhaust headers can fail, its just the nature of the beast. Heat Cycling, high temperatures, stress, material, all play a factor, and even if all of those are in check you can still get a failure.

but like you said, the great thing about metal is every city has a shop that can fix it.
 
FYI: I spoke with Jake today and he will be revisiting the need for a warranty. He will more than likely be offering some sort of warranty. I'll keep you guys posted on that.

Also, if anyone is interested in one of these, now is the time to buy. Jake has lowered his price to $649!!
 
What is the purpose of having two wastegate's? For running high boost I suppose it would be alot more controlable.

Two wastegates are necessary to retain a true divided manifold and turbine housing, and to retain proper backpressure equalization.


drewbird91 - I was wondering who's car Jake used for the test fitting. I think that exact manifold in that picture is the one I ended up buying. Do you plan to run one of Jake's manifolds in the near future?

My plans do't include upgrading my turbo at this time so I am sticking with my evo 3 manifold. The quality on his manifolds are good and I would buy one if I ever planned on going further with the car.
 
This is pretty sexy and a great price I think I'm going the T4 route instead of T3 bc of this manifold
 
"The warranty covers cracking and other manufacture defects to the original purchaser. "

that's what he e-mailed me. I'm ordering one probably tomorrow. First Non-ebay part
