the louder the better, being loud makes you seen faster which makes other people laugh, win win!

[zdeezy19]

[jettamk5]

@zdeezy19 This, I want a testpipe, but worried about stupid cali cops smelling it and pulling me over. My cat location is right behind my turbo under the hood, so they can check it easy.

@joeaccord23 sound is a type of energy transfer (motion to heat as in breaks) sound is loss of energy good try though

^ Agreed, which is why mine is off the car with the stock cat back on.

[MrHimself13]

its because it pollutes the air.

[dyeballer92]
