wsoape... adding just a tip wont do anything performance wise.
ihave a 4" tip i bought at canadian tire, and it did nothing, it didnt change the sound, or anything... it's there just for the looks..
and until i get my hks catback system.

and take a look at the tip i have on my car.. is that something your looking for jim? it fills the rear bumper hole quite nicely

Yes, something like that. I can get the Ebay tip I like for about $40 shipped ($25 + $15) but I'm going to wait until I see what the muffler shop has. I've gotten to be friends with Darrel and Mike who own the muffler & brake shop I use. I'm sure they'll have something or they can get just about anything, I'll just look through there catalogs and have them order it for me.
