Seannyc we typically see a honest 20-25hp with no tuning changes. I don't like to bs people with crazy high hp claims that ultimately are not possible. When I tell you 20-25hp I'm giving you a number you can count on. I've tested them side by side with every major brand headers available & what I can tell you is I'll put the TSP headers against any of them!!
