RN SJ Exhaust Tube Quick Question

[smoofers]

Hey all,
I'm installing a RN diameter exhaust tube in my SN. I need to know approximately how far the exhaust tube sticks out from the firewall in the engine bay. Thanks.

I would guess about 4-6"

Thanks BK, would like somebody to measure if possible.

You have the rubber hose from the Waterbox already, Mock it up, then see how much tube you need to have proper overlap. Also, but sure it is far enough away from the carbs. Mine on my edge rubs the pump side screws on my Blackjacks. Pipe needed to be closer to the side.

The edge of the masking tape is where it ends on my rn. Mine is 7/8” longer than stock because I replaced my tube with a 36” tube that I didn’t cut shorter and welded it on the flange. So 5 3/4 - 7/8 = 4 7/8.

Perfect, thank you!. I mocked mine up and found I needed a minimum of like 4.5". This is great info to let me know I'm in the ball park!
