There are many different discussions about this but I want a solid answer, I plan on purchasing an exhaust cutout for for 4 cylinder naturally aspirated, with a switch to operate it. I'm going to use it rarely, but I has heard that the lack of compression will give me less low end torque, will it give me high end torque then? Or just loss of low end. I have also heard that cool air will go back in and cool my Valves and warp them? Is this true, or at least for te aplication I am using? What's the difference between an exhaust cutout and a borla exhaust or something like that? Thank you:3_usehead
