I considered using exhaust wrap on my DP but i read a bunch of threads that recommended against it, mostly because moisure could become trapped and make things rust. I would also be a little concerned about potentially overheating the cat on really long pulls or hard driving but not sure about that part. If i was catless i would have definitely wrapped it. |
The owner who ceramic coated my catted downpipe said that when he coats catless downpipes he does them completely inside and out. The ceramic coating discourages the metal from being a heat sink and flows the heat right through to the exhaust.
I did my DP in black a few years ago to fly under the radar. Looks more like a shadow underneath and doesn't stand out. But they have a lot more ceramic coating colors now. I snapped a photo that I will attach.
I'll post a link in case someone reading this is interested. They do great work and people ship them parts to coat all the time. They are in PA.
