so i got my exhaust manifold today thing its pretty sweet it should bolt right up correct about 15 mintues to do depending on how bad the bolts are?

 

what brand is it? some need a little coaxing to go onto your current exhaust. if its a headman chikara - ur good to go.

 

No its the eBay cheapy that isnt worth the money... check out inside the collector area and you'll see that the manu squished the size of each tube down by half to make it fit so your flow is restricted to half the size of the exhaust port. This isnt going to help you at all, in fact it will probly be worse.

**add

I think thats also for a SOHC

 

dont see the problem its an obx header it slipped right into place and bolted right up sounds way better and i can feel the high end power difference
