Exhaust Manifold: Best option for FI

Starting a new project car; the last owner had put an OBX header on, which I'm not very impressed with. I could put the stock header back on, but since I want to show and 'cross the car, I wanted a hi flow header that looks good and is durable. The motor will be supercharged once I'm satisfied with the exhaust, ignition, and fuel systems.

Right now, the ExoticSpeed header is at the top of my list; it's mandrel bent and has a common collector for the 02 sensor, unlike the OBX and Re-Amemiya headers. Any recommendations and/or experiences are appreciated.

How about this one? Ceramic coated and has a common collector for the 02 sensor.

The reason I recommend the DNA motorsports headers is that it was designed to be used with a supercharger, plus it is the only ceramic coated header available. I cnat remember the cost but I dont think it is too much more then the racing beat header.

Good info on the RB; didn't know about it. Do you run one of these Rotr8?

I did check out the DNA header, ceramic coating is nice. The weld look a little spotty in the pic, will have to dig for the price/availability since it comes from Oz. OK, so ExoticSpeed, RB, DNA, and anything that mounts a turbo, got it. So far so good.

Actually the best manifold would be one that collects past the cat like the one Eric Meyer was talking about . Unfortunately no one sells one ..................yet .

i didnt really find them. eric meyer passed me a long their site. :P

for their race headers, you'll have to jump through some hoops. apparently eric meyer owns part of the design, so who knows how he'll part with that. i asked.

/\ i'll bet if you just took the street header design and just moved the collection point downstream a foot you would get damn near the same result .....
