Best reply yet .....Bimbo, there are a couple of dyno sheets out there.... but overall it would be hard to tell you exactly how much each header makes because everyones build specs are different. The best advice I can give you is to check out (Bills) thread......wait a minute......BAM>>>>
http://www.sr20-forum.com/vvl/20083-headers-dyno-comparison-thread.html That should have most of the info your looking for. You don't have to spend that much either if your on a budget, the ssautochrome look alike is a decent option for 5 times less the prices as well.
