holds up to what better? are you talking about discoloration or rust or heat or what?
it really doesn't seem to matter if the dp is stainless steel or aluminized steel. the aluminized steel will get a light coating of surface rust, but it won't rust through for more years than you need to worry about due to the thickness of the metal. the coating will make it look a little prettier and help retain some heat w/in the dp and keep the engine bay cooler.
if you are ****, get a stainless dp, jet hot coat it and then wrap it in header wrap to get heat out of the engine bay. if not, get any used dp in the classified section here and wrap it in header wrap and you'll be good to go.

The best choice is heat coated stainless steel.

^ I had a DP coated with the 2k stuff and it was crumbly like the outside of a stucko house. Perfomancecoating says theirs is smooth. Mr Stock's was smooth. He had his TriPoint DP blue 2k coated at Jet Hot. So since the DP was polished, I thought it sucked to have such a rough finish. Also, the coating came off around the holes on the flange after just test fitting.

GoRacer is right.
I had mild steel and stainless and SS does sound louder.
U can hear the turbos.
I had the SS ceramic coated and the heat reduction is better than with mild steel downpipe.

My friend Jet-Hotted the ENTIRE exhaust when he had is blown mustang. When we got the exuast back, the coating was as hard as steel.
After we installed, we noticed a HUGE differance in cockpit temperatures. We went from sweating to no more sweating in the interior.
I can't comment on the smoothness. I guess it's just a matter of preferance. But to say if the texture makes a differance I dunno.
