Berk HFCs on Factory Nismo Exhaust *RASP*

QVu

I went from the factory Nismo exhaust and Berk HFCs setup which was raspy, to a FI CBE with the Berks HFCs. 1) To see if the guys at FI could prove that there would be zero rasp, 2) To go with a louder exhaust, 3) I liked the look of the cans from back, and 4) seemed that many people on the forum loved the product.

I now have no rasp, only the hiss on hard accel and lower rpm decel, which is typical of the car.
