im pulling out the entire exhaust system for fun and im wondering if i can wirebrush the hell out of the inside my manifold(N/A). to clean it out and mabye open it a small amount. Why would i do this? Im not sure,, but what would happen if i did?

 

It would be the same as it was in about... 2weeks

 

you'll end up with a clean manifold and ten less hours of your life
