What's the bestist for the leastis? Or somewhere in between!! I have pretty much decided on a RB Cold air Intake, but I can't decide which header to go with.

All headers are worth about the same power on a typical 1.6. The only advantage is quality. A Raceland header for $150 will do a great job for very little cash, and is only marginally worse than most of the high-end stuff as far as fit and weld quality. I've seen plenty of cracked RB headers.

The header cracked after 2 weekends of road racing, I am running 70 duro supermiata motor mounts and the whole car vibrates like crazy. Got a new header and my welder fixed the cracked one with beefier welds. If the new header cracks as well, I will have a flex section welded in.
Thanks guys. I think I will try the Raceland.
^Whatever you do, don't get a 4-2-1 layout (like an OBX)...much harder to get in and out of the engine bay! Raceland (aka, Riceland) uses the Racing Beat design.

Unless you did those pulls on the same day, on the same dyno, its hard to consider the specific numbers, but they do show a typical range of gain from better exhaust. Again, any header will give similar gains over stock, so don't sweat the high-dollar stuff.Quote:
