Hmmmm X-Force 4'' Cannon in my car is so ****ing loud can hear it inside the car, gets annoying, anyone recommend me a muffler tip to buy for around 50-70$, What some other good brand and not too loud. I simply can't afford the $300 tips, this time should I go on 2.5'' will it decrease the loudness since the one I have now is 4''.
