nah dude. they're factory. but they're the ones that come with that rockford fosgate system.

i used to be into making my civic's system uber pimp... but i assure you, this system is no push over.

regardless, i have 0 experience with aftermarket mufflers. so i just wanted to find out if it would be annoying at all... or kinda like that logic behind getting a tattoo. *sometimes you're glad you got it, and most of the time you're not*
