What do you mean TIP? Isn't that for the ricers?
For arbout $40 you could buy a used aftermarket muffler like flowmaster or magnaflow, or a brand new cheaper brand like Thrush. You want offset in / offset out configuration. I believe the stock V6 exhaust is about 2 inch but a muffler shop should be able to reduce 2.25 or 2.5 down to 2". Should only cost about $40 for an exhaust shop to swap a muffler out.
