That the strange thing. When I had my custom exhaust on the pink spring gave me around 11,600 and the pink was 11,080. When I went back to the stock exhaust the pink spring rpms were 11,800 and now running the green I'm at around 11,400. I'm thinking the stock exhaust is giving me a little bit more HP.
