@topspeedauto

Hey ive had mine on for about a month and its gotten a lot quieter than it was when i first installed it. I have no idea why...is it supposed to do that

[ghostreign]

@nitish21 As carbon builds up in your exhaust pipes it will act as a resonator causing the sound level to go down.Getting a y-pipe will give you some more power and a better sound!I have a stillen y-pipe with my pro1.

@ghostreign i do have y-pipe its just off the mid pipe i dont know if its a special type of y-pipe but the guy who sold me my exhaust and installed it changed the midpipe added a y-shaped pipe that split to the two mufflers
