Panhead exhaust flanges

#1

Post by roblenzz » Sat Apr 21, 2012 12:35 pm

Hey guys, new guy here with a question. I just bought a 1965 Electra Glide and ran into some trouble. I'm slowly finding out things about it that make me cock my head and say "huh?" But my last issue is that it has STD heads. Not a problem per se, but I just ordered a set of OEM style Paughco exhausts for it but will now run into the trouble of connecting them since it has the 3 bolt mounting. Does anyone make flanges to fit the 3 hole with a necked down short piece of pipe to allow the clamp style exhaust? The worst cast scenario is the the thickness of the flange will cause everything to be off and nothing will mount correctly, does anybody else see any possible problems? Thanks, Bobby

Hog54!

He wrote "3 bolt mounting". Shovels have one.
It sounds like the heads were assimilated to evo.

On STD heads the middle bolt hole is in the same position as a stock shovelhead exhaust.You can use a stock shovelhead exhaust on std heads and not use the other 2 bolt holes.If you want to use all three,you have to cut off the stock shovelhead exhaust flange on the pipes and weld on the 3 hole one.Or you have to buy one of these kits.http://paughco.com/2008-catalog/indivpa ... ughco.html" onclick="window.open(this.href);return false;

The 3 hole flanges usually come with the heads.

It must have taken a whole committee of engineers to come up with that.

Thats how the heads were when they first came out.Now they make them exact replica.

You can still get them 3 bolt exhaust,but there must be 30 different versions of them.lol

John!

When I worked for the government, we had a Department of Redundancy Department.

Three bolts into an aluminum head casting counts.

Roblenzz,

Contact STD development and the can get you a set of the flanges pictured above. You then fit up your new pipes and have them welded to the flanges. Pretty simple once you have the flanges.

Thanks for your response guys. I understand your question of why didn't you order shovel exhaust. It was a mix of not knowing what I had at the time of ordering and just taking it for face value of "Yeah, I have a panhead" "Oh wait they are STD heads and that doesn't mean "Standard!" Yeah, I'm pretty dense. The clamp style panhead exhaust is already on the way and just wanted to try and come up with a fix without sending it back and still have the look of original equipment. In the event I find some "closer to original heads I don't want to buy another set of exhaust headers. The picture of the gaskets is what I would need also but what I was looking for is more like this:

Forgive me for my poor drawing, But kind of like this, but necked down to accept the pan style clamp on exhaust.

You wont be able to install the flanges on panhead pipes.Send them back or cancel the order and get shovelhead pipes.
