Sorry for delay right now what i done besides cosmetic is a down pipe mid pipe and full cat back and that made it really start to open up and its way louder i did borla exhuast but adding a down pipe and mid pipe it makes it sound like a loud exotic next thing i will do is add injen intakes and bov and interooler then i will purchase the jb4 plug tune but what i want to put down is at least 550 horsepower and 600 torque i think i will be there if i run e85 blend gas
