Dual exhuast

Does anyone know an estimate on how much it may cost to get dual exhuast on a 2001 v6? Parts & all. Thanks

i heard midas or some place say they did catback for like $350 or somthin around there. ur better off just gettin a shop to do it.

but they just used the catback mufflers and did the rest themselves.

And what kind of effect does dual exhuast have on the car performance-wise? Im kinda new to this stuff...

like 10-15 hp. if ur just goin with plain dual exhaust
