Man... some people aren't helpful at all... Anyway. Just hop on E-Bay and look for a header that will fit your Prelude, then buy the cheapest one. That would be the way I would go, because you can usually find stuff cheaper on E-Bay.

Or you could always just run the car without exhaust.... Probably sound like a lawnmower... hehe.

I have the DC Sports CC 4-2-1 Header, and love it. If you are going turbo in the future, then don't waste you're money on a high quality header, because you'll just need a turbo exhaust manifold anyway.
