Really?None of the members above said that an increase in HP will occur and that it justifies the cost for performance. I think you might be on glue because you are reading what you want to read.
Dude, that came from the website quoted by one of the posters. All I'm saying is, no need for the hostility.Really?

Minor performance boost. Dyno tests have revealed power gains of 8-10 hp in a 550 hp engine. This is mainly due to the heat barriers trapping heat inside the header pipes and increasing exhaust velocity. It was also acknowledged that more gains could be had when installed in an engine bay, where hot air robs power. Ceramics may also be applied to internal engine parts, creating less drag and longer burn cycles during engine operation.
