I'm fabricating an exhaust for my 1951 Mercury. It has a Flathead with Red's Headers and a Mercomatic transmission. Mufflers are 12" Brockman Mellowtones just forward of the axle. Would anyone with more exhaust knowledge than I care to offer their opinion and/or suggestions for the routing on the drivers side? You'll see it's pretty tight. I've upgraded and relocated the master cylinder, which limits where I can pass through the X portion of the frame. Exhaust routing would continue where yellow lines are. Is this routing too close to the transmission and/or master cylinder, or would I be better off going under the frame?
