uuuhhh ya dude,
If it's just looks you want, just screw on or weld on a tip. If you wanna get fancier than that, then I suggest you buy a chrome after market muffler, in my opinion I think the dual exhaust look the best.
This is only my opinion. Pepole choosing to weld an import style muffler that I have seen had a lot problem with especially cops. If I were you, I would get a cat back system which is already designed and developed by a manufactuer such as Blitz (WWW.ipnmotorsports.com) or JIC ( It would be more expensive).
Something about the Chicagoland suberbs that makes cops want to give motorists a difficult time....
If you live in the burbs of Chicago.. forget about any of the following:
-- tinted windows (ESPECIALLY IN EVANSTON)
-- blue lights ANYWHERE (ESPECIALLY IN SKOKIE)
-- Aftermarket HID that are too bright (ESPECIALLY IN LINCOLNSHIRE)
-- Aftermarket mufflers that are too loud (Especially Des Plaines??)
