"race header" was not hooked to the exhaust right? well the only way to get a GOOD comparison is to attach it to some high flowign exahust... if when welded up it makes 12 hp total over stock vs 17 hp over stock.. id say 5 hp is not worth the obnoxiousnous of open header.. sounds OK on a small block or something.. but sound real bad on a civic..
