If I have the stock muffler system under my car, what inlet and outlet size should I be looking at when purchasing exhaust tips? I see this Ractive stainless steel oval that looks good...It also comes in stainless black steel. Is the 8" lengh adequit? (Size matters)

The old tips will need to be cut off because they are welded/cracked off.

There are several members who have this one

Magnaflow makes some nice dual walled stainless tips also
