Yeah that would make sense. Did you say the header pipe right in front on the cross-over was a 1 3/4"? I only have 20 hrs to wait till the auction ends on ebay! Hopefully I am the winning bidder. I hate waiting....!!!

What do you mean 1 3/4" will slide over it and muffler will slide over the other end? You mean I will need to get an increaser to 1 3/4" to slide onto the header pipe then slide the muffler on that? Or do you mean the header pipe is 1 3/4" and the muffler will slide over it?

ok I see what you mean now. The piece of 1 3/4 pipe, is that going to slide over the header or into it? And does it fit snugly or will I have to modify the pipe to get a snug fit? Then I assume the pipe would slide intop the muffler. Just curious about the header end.
What would I search for to find pipe? I am trying to get an idea how much the pipes might cost but I can't seem to find anything. Should I search for tailpipe? I searched for 1 3/4 exhaust pipe and got nothing.

What is your opinion on the heat wrap you can get for exhaust pipes? Do you think it works? Will it fall apart quickly or start to unravel easily? Thinking if I do get black mufflers I can wrap the headers and pipe all the way to the mufflers. I've never used it before on any application so I know nothing about it.

You can get the 1 3/4 inch exhaust pipe from any good muffler shop.......u will need about 2 feet per side. The pipe will have to be driven over the header pipe about 2 or 3 inches, as it fits tight. Then u can cut the pipe to what ever actual length u need it to be. Don't try to do this with the header pipe connected to the engine, as u can break the header pipe up by where it bolts to the engine. Then, if u want, you could have a muffler shop put a very slight bend upwards to sorta look like the upsweep of the stock exhaust, if u understand what I am tsalking about.

Eagle.I wonder if pipes are sized a different in Canada.I had no problems sliding the extension pipe onto the header pipe. (actually a touch loose) But a clamp tightened it up.Or maybe the header is slidhtly smaller??

I understand what you mean eagle. If I have to drive the pipe over the header cause it's tight, will I still need a clamp to tighten it? I know I will need a clamp on the muffler end of it.

One thing to "caution" u about the hardly d mufflers.......The ones u want, are the earlier model ones...the newer mufflers have an extra hole on the side, near the inlet, for a "balance" pipe, that connected the 2 mufflers. Those holes are really in the wrong place, as when used on our bikes, those holes have to be plugged, and welded shut, and they show when they are mounted. To Ben...the top ones are like the ones on my bike, and I found that they are very easy to mount, and do not have the extra holes I just spoke of.

Well so far I am the winning bidder. Hopefully I get these mufflers as they are really nice. I am going to wrap the headers regardless if I get these mufflers or not. Will be nice if I do cause the whole exhaust will have the black look I want. I've done some research about the heat wrapping. There is also a high heat silicone spray to put over the fiberglass wrap. I will be putting that on as well. I will have lots of pics to post when I get all the work done. Eagle: I seen the holes your talking about on other mufflers I was looking at. One reason I am looking at these ones. I am eliminating the cross-over pipe for a reason. I don't want another hole in the muffler I am putting on that I have to plug. Wouldn't make any sense to get ones with holes. lol Eagle: Once I drive the pipe onto the header do I still need an exhaust clamp if it fits on real tight?

If it fits real tight you wouldn't need one especially if your covering with wrap.As I stated mine sliped right on & i need a clamp.If your not coming down that far with the wrap you may want put one of the chrome clamps on just to hide the seam.

I won the auction. The black harley mufflers are now mine! I am going to wrap the entire header pipe and pipe up to the new mufflers. That way my whole exhaust will be black. It's gonna look really nice when I am done. It should sound pretty sweet too! Blaine I like the way your mufflers look on your bike now. I'm not crazy about that slight upward slant. I think it looks better level all the way back.

Congrats on the mufflers.The ones in the original pic were mounted on the original pipe with the original angle. I like them straight too.But just be aware that if you are a aggressive rider in the turns they may scrape on you.But they shouldn't be a problem.Mine scraped a couple of times when I was riding "two up",but my bike is lowered to 10'' shocks also,making the rear quite low.As Eagle stated to could put a slight upward bend if you desired.

Blaine, For the muffler clamps. I am going to need 1 3/4" clamps or 2" clamps? I was looking at some 1 3/4" clamps and it says the size ranges from 1.89" to 2.13". Would that be the right size clamp for both the muffler end and the header end? I think the 1 1/2" clamp ranges from 1.69" to 1.89". I'm gonna have to get these online as it seems the auto parts stores around me cannot get them and the dealer is expensive. Just want to make sure I get the right size clamps.

By your numbers,it looks like the 1 1/2" are big enough.I had the clamps that came with the mufflers so I didn't need to buy any.Your largest point is at the muffler inlet,as the muffler slides over the 1 3/4" pipe.

I did not have to clamp the pipe onto the header...I had to actually drive the 1 3/4 inch exhaust pipe over the header with a piece of 2x4 wood block and a hammer. I drove it on about 2 1/2 to 3 inches. Now understand, u folks in canada use the metric system, so our 1 3/4 inch exhaust pipe material may not be the same size as yours. And Blaine, my "extension" is a bit longer than yours, that is shown in the pic.

That's what I was thinking,as the pipe slid on the header quite easily (I had to clamp them).I just cut my extensions to were my muffler mount lined up with the original mount on the bike.Plus the H-D heat shield is just long enough to cover the pipe.(not quite sure what model these are off,as they are about 4" shorter than normal H-D mufflers.) Here they are with the shields in place.

I could try the harley dealer. Tell em I need 2 clamps for a set of H-D mufflers I am installing on another bike. See how much they say they are. They might actually have them in stock since they are for harley pipes!
Eagle.. When you drove the 1 3/4 pipe onto the header did you put the header in a vise to do that? If I cut the pipes right in front of the cross-over pipe I think I can go on 1 1/2" - 2" but I'm not sure it will go on 3". Kinda looks like that is the beginning of the bend upward. How far on the header do you think I need to get to not have a leak? I am wraping the whole header and extension pipe with heat wrap.
What type of welder would need to be used to weld the pipe on? I have a friend that has an arc or tig welder. You put the wedling rod in the big clip and cip the other on the metal. I think my wife's uncle has a flux welder. The flux comes out the middle of the welder tip.
I looked and I can get an 18" extension at Advance Auto for $8. Gonna take a rough measurment once I get the mufflers and see if that will put them in a nice spot.

If you can only get on about 1 to 1 1/2" I would weld them just to make sure they don't move.You dont want them to move after you have everything wrapped.Either welder will work,but the flux welder will give a cleaner bead of weld that will hide easier under the wrap.

I took another look at it when i got home tonight. I think I can easily get it on 3". I don't know a lot about welding. Aren't some welders hotter than others when welding? I've heard some talk about welding and say you gotta watch you don't burn through it. If this is true which of the welders I mentioned be the one that would weld the coolest? I think once I get the pipe on I might just have it welded. Then I will not have to worry at all about it moving. I could go as far as to weld the mufflers onto the extension pipe too. Then I would have to clamp anything. lol I don't think I am going to do that though. If I ever want to change them I will have to cut. Will just get the clamps for the mufflers.

Post by Blaine on Mar 4, 2013 23:27:16 GMT -6
The flux would still be the better weld.If you can get them on that far I would probably just do a couple of spot welds to make sure they can't move.Once you cut the header you will see that they are double walled.The newer Vulcan had a problem of the inner header coming loose & rattling at certain speeds.Only cure was to replace the headers & no guarantee that it won't happen again.

Actually, what I did (contrary to what I said not to do) was tie the header very sturdily to the frame, still bolted to the engine, to keep it from moving, and used a piece of 4x4 to help brace the header even more, then used a piece of 2x4 and a hammer to drive the extension on. That was the first time, the second time, I took the header off the engine, got the extension started on the header, then held the header and slammed the extension down on the block of wood a number of times, till it was as far on the header as I could get it on.

That sounds like a plan eagle. I do want to weld the extension on the header. About the welders, do you think a flux welder would be ok? A friend has an arc welder which from the little I know of welding I think will be too hot, may burn through the pipe. The flux welder I think welds a little cooler temp right? I would like to put a bead all the way around if I can. then there is no chance of any leaks. I picked up 2 muffler clamps at the harley dealer today. Cheaper than I could find them on ebay or anywhere else. Guess sometimes it pays to go to a dealer. I got 18" extension pipes from advance auto. I eyeballed the location after cutting the pipe out and I thin kthey are going to be good. I am gonna check everything once I get the pipe cut off and see before I bang anything together. I can always take em back and get a longer piece. But like I said it looks like it's gonna sit in a nice spot. and it should clear the kick stand. Can't wait to get the mufflers installed so I can wrap the exhaust, then let it dry so I can install it!

I started my exhaust modification today. I have the stock mufflers off. Got the cross-over pipe cut out. I'm gonna have to get the extension welded onto the header as it doesn't fit tight. It tightens up a bit but not real good. Don't want to put a clamp there. Also I am going to have to have the extension bend in 2 spots. The pipe will rub on the kickstand when up. Also the muffler will be too close to the drive belt and back wheel. Will have the muffler shop put a bend in the extension right after the header, slightly under the bike. Then have him put a bend near the kickstand so it bends back out away from the rear tire. I'm gonna trailer the bike down to the muffler shop so he can bend and fit. That way we will get them bent just how I need them. Should work out pretty well once I get them right.
Question about wrapping my exhaust. I was talking to a friend about it and he brought up a good point. The exhaust radiates heat off from the pipes, hence helping reduce the head/engine heat. If I wrap the exhaust it's going to reduce that radiant heat loss, hence it might increase the head/engine heat. Any thoughts on this on how it might affect the bike? The exhaust isn't that long on our bikes like on a vehicle. I'm gonna make a post on the vulcan forum and see what they have to say. Any thoughts about this are greatly appreciated. I may not wrap the exhaust if it's going to cause a problem.

That's the way my header pipes were,just slipped on to the header.I can't see the header wrap being a problem on our bikes because they are liquid cooled.If they were air cooled it would concern me & I would have mentioned it.

Thanks blaine, that's kinda what I thought. Talking to my friend and thought it was a good concern. I made a post on the vulcan forum too. See if anyone has wrapped their exhaust and how it is. The extension pipe doesn't fit on real snug until it goes on about 2 inches. Then its not real tight. Im gonna have it welded at the muffler shop. Ill have them bend the pipe to make it sit better for the kickstand and the rear tire and belt. Once I get it the bend I want ill have him bend the right side in a mirror bend. Then ill just have to fabricate a mount piece.

Hey blaine, after I got the pipes cut off I see what your saying about the header being double walled. I am going to have the muffler shop put a couple tack welds on the header so it doesn't rattle. Don't know if it will but since I am welding the extension onto it, better do it before I weld them on. Then there will be no chance of the rattle.
