Header Flange Smoothing - More Needed?
I have completed the smoothing similar to Cmax's:

Was wondering if spraying some high temp paint on the smoothed part would be needed to prevent rust? I know Cattman y-pipes are stainless, but I just want to double check. Thanks guys.

Yeah. My only reasoning for painting would be as a preventative measure to prevent rusting of any sort. Especially since it's been dremelled down. Not sure how the dremelling will effect rust...

Don't waste your time painting the interior of the ypipe, it's useless! Unless you're spraying ceramic coating your wasting your time. Plus it's not going rust that close up to the engine, too much heat! Most rusting in my enviroment happens farther downstream on the exhaust system. Also to answer a question from the original thread, the flanges are all mild steel and yes the tubing is SS. But thanks for the mentioning, I personally like to clean up the weld globs, and splats that could interfere in the exhaust gas flow!
