Exhaust question............
 

I have a 3.0 and want to replace my exhaust tips with the 4.8 style tips. What is the best place to buy these & how much should I expect to pay? I almost bought some Ractive tips, but decided against it until I had more time to shop around and see what's out there..........
When I do buy some, I will have some like new OEM chrome exhaust tips for sale if anyone is interested.......

Thanks for your help & info...................
