Exhaust sound

hey guys i just recent got a 2 1/4" cat back installed last week, and for some reason now the exhaust sound is different. i have no idea what would cause it to be different. anyways what factors go into a sound of an exhaust and how do they they effect it. could i just be used to it?!?! thanks

Probably the muffler getting broke in, fiberglass and/or other materials have been heat cycled a few times so there sound deadening charicteristics are getting broken in. Also could be your ears.

yeah ^^ what he said it may be broken in or is breaking in

thanks for the input. if its being broken in, is that the ehaust will soundlike? or does it go away?

sound will stay

somthing tells me he doesn't like the sound of bee's in a can

He probably doesn't have a resonator...resonator's do help on the "raspiness"
