This is this guys first post ever on the forum and this is your reply ? Chevy built your car with a pair of exhaust manifolds. Hooker makes a set of shorty headers for it. I would recommend a set of longtube headers for it. You will get a real performance gain from a set of longtubes. The shorty headers don't do much for performance, which is what CFI EFI should have said rather than being a smart ***. You can get longtube headers fromwww.summitracing.com

Chevy built your car with a pair of cast iron exhaust manifolds.You need to double check your parts book. 91s (not sure what other years) did NOT have cast iron exhaust manifolds. They had stainless steel, tubular exhaust manifolds that, as CFI-EFI pointed out, are very similar to shorty headers. Chevy switched to cast iron mainfolds in 92.

Yours should have them to, as CFI-EFI pointed out in his own special, way.

They may Not be made out of cast iron as they are on every C4 I've ever seen but shorty headers they are not. A set of Hooker shorty's might gain 5-9 rwhp. A set of longtubes will double that.
