Gruppe-S UEL, people may tell you otherwise but dude 475 compared to tomei's 675 price. I can't think of other headers for that kind of price. I honestly think this is the best bang for your buck, there was a guy running the Edelbrock supercharger and he made 297 to the wheels with the Gruppe headers.
