How are you guys with a '40 routing the L/H header pipe when running duals? Seems like the clutch linkage and brake lines are in the way from running it thru the frame cutout like on the other side???? I plan to run Red's headers on my wagon.

I did it on my 40 coupe. I used 1-3/4" pipe and threaded it through as best as I could - it is very tight. I had to put a dent in the pipe to clear either the pedal or the relay lever - not sure which now. The coupe was a body off job which made it easier. On my 41 pu I chickened out and sent them up the right hand side. I used a Merc manifold on the right with an inlet at the front and a single outlet at the rear.

Reds sells the pre bent L/H header pipe that's used with his headers.
I used his system on my '39 some time ago and it fit perfectly.

^^ The pedal layout is different between a 39 and a 40. Not saying it won't work in a 40 but the 40 is tighter due to the relay lever.

Yep. I agree but I believe that Reds has taken that into account.
To be sure, and e-mail or better yet, a phone call to Reds to confirm
the fit would be in order.

I used Speedway headers and my local muffler shop routed the pipe through the stock hole in the frame on the left side. He knows how to bend the pipe and put a slight flat spot in it to clear the clutch pedal and mechanism. Everything works just fine. The shop I use is very familiar with old Fords.

Like Mart, I also used the "dent" approach. Twenty years, still clears fine.

I recently installed a set of Reds headers & exhaust pipes on the '40 coupe. They fit fine. It is a little crowded on the driver's side, but orienting the pipe the right way clears with room to spare. No dents needed. As side note, I used 12" " Mellow Tone mufflers from Mac Van. I tried 18" one, but not enough room in the X-member without cutting the frame. I had the tailpipes mandrel bent by Tubular Automotive in Weymouth MA.

I just had duals installed on my 39, 22" Brockmans. Love it. Anyway, I checked with Red's regarding his pipes. They only work with his headers. They don't make them for stock manifolds (in case that's what you are doing)

On my 40 the pedal arm hit the pipe. I heated it red hot and slammed the clutch down to dent it. That was 25 years ago. Still working great .
