There is truth to the coated ones being overall a better way to go for an all out racer who needs ever bit out of the car. Thermal dynamics comes into play when they are coated and since the heat is trapped inside the pipe more than a non-coated pipe the air will move faster and basically flow more. that difference is not going to be seen or felt on the street. If you plan to track the car often then I say go for the coated ones for sure.

Wow..you are speaking of oil temps right? How the hell are you running so cool?? I have the HPF intercooler, no tune and a bms intake and when driving aggressively after the car has heated up, its always at atleast 230 unless the outside temps are below 75. Its gotten up to 250 a couple times on real hot sunny days with mostly stop n go driving as well. Are you running meth?
