Wrapping is good, ceramic coating inside & out is so much better.

As far as I am aware, there is no particular reason to wrap the cat delete pipes. The stock cat pipes are not wrapped and there is sufficient heat shielding under the car. All of the pipes that I have seen (along with the primary cat delete pipes on my Spec Boxster) are not wrapped.
On the other hand, I am not aware of any particular reason not to wrap them if you wanted to try and cut down the radiated heat around the engine area.

Hotter air flows faster, my trunk stays much cooler too. Ceramic coating headers has to reduce oil temp in the heads where the pipe nearly touches the chain housing.

the car bypass pipes are just fine unwrapped. the removal alone of the secondary cats will lead to cooler trunk temps (as mentioned above). additionally you would need to dismember a body to fit it into the rear trunk, so they will not be complaining about the temperature. the only real "advantage" I can see out of wrapping the cat delete pipes is the addition of a substance which will hold road salt and moisture against the pipes, enhancing the corrosive properties of both.

Thanks Everyone
I was thinking while driving today that the pipes are not wrapped or shielded only the Cats...so I will not wrap them. Worst case I could always take them back off and wrap them.....Road Salt is not even an issue in Alabama ...besides I never drive this car in the snow (rare we even get snow) and rarely drive it in the rain.

Is the ceramic coating a common process at muffler shops? Or, where do you get it done? Any idea on cost? Just curious.

No, most busnesses that apply coatings specialize in that only. Go online to find a shop near you. Works much better if the part is new. About $70 for the secondary pipes inside & out.

jet hot is a company who does the ceramic coating, I have friends who have used them before, but it is expensive. the cat bypass pipes are stainless (usually), there will be little gained from a performance or longevity standpoint. usually this process was used to prolong the life expectancy of mild steel headers which tended to rust out rapidly.
