Anyone have any experience with aftermarket exhaust applications that improve performance?
I just had the Aero Turbo muffler with 3" e-pipe installed. The truck now sounds neat, but I don't believe I've realized the boost in performance and gas mileage this product boasts. I'm still getting about 12 mpg.
I'm now considering replacing the 2 cats with a single aftermarket 3" cat. I was told that this will add approx. 30 horses.
Am I wasting my money?
