muffler
im gonna be straight with you, glasspacks on your car is gonna sound like a pissed off bumble bee, a normal thrush or cherry bomb glasspacks dont flow all that well, and as for them deteriorating, thats not that much of an issue, theyll last for a decent amount of time, dont buy them thu, IMO dont buy any straight thru muffler like magnapacks,loudmouths, or stingers, dont buy a borla catback either, stick with either the flowmaster 40s super 40s or super 44s, or a mac catback, its the best your gonna get, this is all in my opinion but id rather have a sixer that sounds good then one that has what like 2-4 more hp and sounds like total ****, be honest no one buys a stock sixer for the speed so go with the flows or mac and save yourself the humiliation of having a sixer sound like a civic
