Topic: exhaust rust issue!!!

[Xander^]

hey everyone, happy thanksgiving to fellow Canadians!

wanted to get some input on what to do with my exhaust. i bought a 4into1 Carpy exhaust from a friend with 2 riding seasons on it. It is the black ceramic coated one that carpy sells. long story short, it was wrapped since purchase. since i've bought it, its been sitting in the garage for 8 months while i progress with my build and now i went to remove all the heat wrap and discovered all of these rust patches.... picture below.

ive since started trying to sand off the rust but not sure what this will do to the ceramic coating. and my intention is to wrap it again..

what do i do!? what is the best way to go about this.

Under the rust the ceramic coating is gone so sanding will just expose bare steel. Of course the sanding process will remove the surrounding good ceramic too. I would probably just spray it with some rust reformer and wrap it again. With the wrap it’s going to start to rust again anyway so it doesn’t really matter.

Oh I agree, don’t rewrap it. What I’d do is blast it clean and have the ceramic coating professionally applied inside and out. Pipes will last a while and look a lot better than if it’s wrapped.
