thought hv3 also loses some low end torque and was for top end..??Yea it'll work just fine. The reason why some may say if its n/a not to go with them is because you seem to lose some low end torque. But if your adding a Hv3 you'll gain that back. The more the car can breath the better off it is.
dont forget the tune!LOL nice analgy. Also I ate a carrot today and can see through walls haha. OK sounds like Headers and HV3.
The change from stock to my Overkill PCM was like night and day. Overkill is in Canada, so you could get a in-car tune.
