black widow back is very typical for a dual exhaust. you should look into it.

the piping would cost about $70 if you just go for the axleback y-split and not the entire catback (since you're not looking for performance) and you can just go with two universal mufflers for like $90-120 each.

and yes, performance has done nothing. if i were going to go for performance i would have gotten a Mustang GT, Z28, WRX for the price of my car ($25,900).
