if ur looking to keep power. make sure u have 2.5 inch piping leading to a 3 inch tip. otherwise ull lose power. i had the greddy exhaust cause my original plan was to TT the car but i decided to keep it NA and get cams and all that so im getting a 2.5 pipe leading to a 3 inch tip made so ill bring my power back up.
speaking of which. i have injen CAI with ppe LTH going to the greddy exhaust and i got it tuned and dynoed but for some reason he said i was making 317 to the wheels... but i read about other ppl runing 330 to the wheels with only short ram intakes... im curious as to why im running less whp with full bolt ons then some making more with just short rams...
