slowboy racing exhaust manifold

[pianoman]

I was wondering if anybody on here has tried that new slowboy racing exhaust manifold? I would like a nice dnp header, but i don't have the money or the need so i figured i'd get this. so what do you guys thing of it?

I've seen it on their website and it looks nice. the runners are bigger than the evo III manifold i would say its worth it.

I was checking it out too. It looks well worth it to me also. Nice price too...

I have one. My car should be up and running within a week or so.... New baby slowed down the process.

Anyway, the manifold is definately a good piece. I just have to enlarge the runner openings a bit to match my head, not a big deal. I also had them port it a little to get rid of the casting marks. I thought about porting it also but there really is no point to that. I will let you all know how it goes on when I am done. Oh, and I do not think I will have to "dent my waterpipe" on my car because of the turbo I have, which is a good thing. If I do, it will be very minor. (GT3255 from PTE, TO4e comp cover)

I just got one. I got mine ported. I installed it with a 16g so i don't know how much of the increase is the turbo or the manifold. The flanges are definitley thicker, had to get a couple longer studs.

 

[pianoman]

so you had to put longer studs in the head?

Actually it should say 'have' to get some longer studs. I used the stock ones and stripped two holes (might have been stripped already). I guess they are M8 x 1.25 stock. I'll see if i can find longer ones.
