“Best upgrade you can get for the FL5 Type R. Induction sound of the Engine is much better, can finally hear the engine. Feel more confident with downshifting gears at higher speeds now. Also, has gotten rid off most of the 1st to 2nd gear grinding. Little vibration when I first start the car but nothing too annoying. By far the best $350 you can spend your FL5 CTR. Highly recommend.”
