What's the best chrome exhaust tips to get? I know there's plenty out there.

 

Man for something simple like that you should have no trouble finding one. Just google "chrome exhaust tip" for a 2.5 inch exhaust and go from there.
Your local autozone/ advanced auto parts store should have some on the shelves too.

 

I have a Gibson slash exhaust tip and I like it. It's a 3" to 5" and looks pretty good. It's all personal preference though.
