your a youngster still so a after market cat back or mufflers you might like, but most of use dont bother cause it will never have that v8 sound, ever. then they tend to drone like mad and will make your ears bleed.

nothing ive heard via vids on line, or in person (heard a slp cat back in person) not for me. unless you like popping back fires when you let off the gas and sounds like a raspberry when floored with some drone, go for it lol

most will say install a open cone filter, headers, drop to a 3.4 pulley get a tune and enjoy the whine. sounds better then the exhaust always lol
