Yes but I’m going to recommend backing off on making the pinch that big. When I’m grinding an unknown thickness area like that I go real slow with my burr. I can actually hear changes in sound and I think I’m getting thin, to thin. I have the exhaust to do and a job on my black duster. If I get a chance I’m going to probe around with a pick. If it’s thin I’ll run a bead of weld on it. I’m trying to find a safe number for you guys before I touch the common wall. For sure I will be hitting the roof some too as it runs downhill to the pinch. I want to be able to flow both the intake and exhaust at the same time and hopefully I will only have to flow the exhaust once.
