i never heard of a problem like that at all, i know you cant feel a difference with non catted.

no heat issues after driving 3 hours in the car with AR catted pipes

save yourself some money and gain a little more power and buy the non catted.

john boxter · 10-06-2009, 02:06 PM

so whats the point of ceramic coating?

badass1g · 10-06-2009, 02:40 PM

i wouldnt bother coating unless you get cats with the setup.

the coating will help with rusting but it is also going to keep heat in the pipe, but I think those are stainless so rusting is not really an issue.

Just had mine put on. I noticed a very nice change right away. The car feels a lot more unrestricted. You notice the better responsiveness. You also hear the air sucking more, but also hear the wastegates a bit more too. As far as I can tell, that was the only thing I noticed so far. This weekend I am going on a 600 mile round trip and will report back. I have the catted AR DPs, and so far I only have positive review to give. No vibration or droning either.

I also have the catted AR Design dps and have taken a couple of roadtrips. Funny thing, I didn't have the stereo on very much as I recall.

Ahhhh, the sound of a nice exhaust note .......

The ceramic coating will keep the heat in although this should not be reason to do this as you do not feel any heat with the catless in my experience.
Generally the purpose of ceramic coating is that hotter air moves faster thus being less restrictive although in the 3 inch that is not really a limitation.
Ceramic coating is relatively cheap in SA so next time my car stands I am going to have them coated and see the difference. I am a idiot for not doing it this time round.
