I'm looking to eke out the last few HP that I can with my Edge. I'm looking at probably 15ish to 20ish HP which would put me in the 315 to 320 range (Not at the wheels though). I already have a K&N high airflow filter (Not a CAI) as well as a tune. Its about 295hp at the crank but less at the wheels.
1. MagnaFlow Street Series Cat-Back Exhaust system. They say up to 10% but I'm assuming more like 3% to 5% which will be about 10 to 15hp
2. I'm also looking at BBk 73mm Throttle Body or a cheaper same size alternative. I found this post (video) on here. Would I be limited to the pipe size on the back on of the throttle body? I also found this video (Time stamp 1:20). Yes its a 3.7L, but do you think I could see a nice increase at low RPMs with the 3.5? Especially cuppled with the exhaust, tune and high airflow intake filter?
