    Extrudehone vs. OBX/aftermarket exhaust manifold

    I'm considering either one. Which will give better results? It will be used in conjunction with a free flowing intake and exhaust system. Thanks in advance.

    If you need a spare exhaust manifold for porting and polishing, I have a spare one for sale. http://trdforums.com/forum/showthread.php?t=32394

    Either way will gain you the same power and benefits IMO. I just went with the Forza header because I didn't have a spare manifold to port and polish at the time.

    if you are going with the OBX header, make sure you have a lot of patience and make sure your mechanic does too.

    Agreed. I was this close to cutting it off and throwing it in a junk pile. Exhaust leaks, cracking, fixing, welding, flex pipe, more welding... and now a rattle. The rattle I can live with for now...

    so far for me. exhaust leak, bad o2 sensor, o2 sensor bung is fucked on the header. 1 step away from port polishing one from a junk yard.
