How far should I have to stretch the clip to get it on? Seemed like I would break it if I spread the clip apart far enough to go on.

Also, which way does the gasket go in the exhaust port?

WEAR safety glasses when spreading the clip (and gloves). All the clips are the same: Blast, Sportster, Big Twin. Usually you can slide the clip on the pipe before you put the muffler on. Or (like fitting piston rings) bend part of the clip under the lip and work it around. There are also 'clip' spreaders. Yes it feels like it will break (and might).

Gasket is fat side in so the pipe fits into the taper. When you pull the old gasket out it should look much like the new (tapered) gasket going in (except really beat up).

You're gonna have to stretch it enough to get it on, no way around that. : ) I know it looks fragile, but I've done it a few times and it just snaps on and returns to its shape.

The tapered part faces out to the header. The square edge goes into the head.

I am assuming that the flange will fit over the pipe without the clip on? Some pipes have their own 'clip' built into the pipe. I doubt this is the case though (but I've never see a D & D). The D & D came with instructions? You should also follow the torque sequence in the manual.

The install instructions that came with the exhaust don't mention anything at all about the gasket or the clip. I'm going off the installation instructions in the Buell factory service manual for the gasket and clip.

The torque sequence recommended by D&D says to mount everything loosely, and begin tightening bolts starting from the back, working your way to the front and finishing with the bolts that connect the header to the cylinder.

Sounds like I'm going to need a clip spreader because I can't seem to get the dumb thing forced on there.

Tight fit for sure, but you should be able to get it on there. One thing I noticed, I did it 2 weeks ago, you don't only spread it apart, but you can get it "larger" by making the clip bigger. Sorry, that's clear as mud. Think of it as pulling the gap apart as left/right, but also up/down. It will flex quite a bit but retain its shape once installed.

From that picture it doesnt look like the ring is needed. Does the flange come off the pipe? It looks as if the 'clip' is built into the pipe. If so there isnt any reason whatsoever to use the 'clip' (snap ring).

The lip pointed out as "attached" is a part of the header and is NOT going anywhere(atleast not without destroying the header). The piece marked as "loose" is not attached. I'm not sure which piece you are referring to as the flange?

The "attached" piece is what was making me originally question the need for the clip. Although if I have the gasket in place I'm not entirely sure what the purpose of the clip is either way, I'm just going off the fact my service manual says I should have one at this point.

although looking at the stock header, that "attached" flange doesn't exist, the and the clip sticks out like it does.

I know I switched the stock one over on mine, and used a new gasket - it installed fine.

Ok, I think I've just been confusing myself and have been ignoring the "retaining" part of the clip's name. That's just supposed to keep the header from slipping out of the piece that bolts to the cylinder, thus retaining it, but my new header has that lip built in which means that it is NOT a problem and the built in lip will function as my retainer.

no problem.....I appreciate the advice Gearhead, as well as EZ and krjoseph.

I was getting thrown off because the D&D installation instructions do not mention anything about replacing the gasket or the retaining clip. I looked at the service manual which said I needed both, and without thinking it through I went out and picked up a gasket & clip. It wasn't until about 10 minutes ago that I actually realized what that clip was for

From the pictures, it looks like it would fit with the gasket removed...

He duplicated the top part of the header turning it into 1 3/4", welded it to the stock exhaust, then drilled out a hole and widened the stock a bit - I think 1 3/4" - the article though is in the useful to know file section

There and in the exhaust archives here you'll find the spec.s.

Well I finally got it installed this morning, sounds great, but holy $%#& is it loud!! I think I'm going to need to invest in some ear plugs, and my neighbors probably aren't going to be too happy with me this riding season.......anyway, here's some pics.

Here it is all wrapped up and ready to go


on the bike




And on the plus side it was 45 degrees out today so I got to take it out for the first time this year : D That header wrap makes for an interesting ride, every time I went through a puddle the wrap would get soaked and I got quite a few strange looks from cars while I was sitting at stop lights with the wrap steaming away. I haven't rejetted the carb yet so it will be interesting to see the difference made by that, I'm thinking that will be a project for tomorrow afternoon.

Looks great! I like the look of the wrap too.

I'm thinking about maybe switching to a D&D exhaust from stock. Can anyone describe how loud it really is? I mean, I don't want it to be unbearable while I'm riding. And I definitely don't want ear plugs...

Oh, and really #@&%ing loud isn't descriptive enough!

on second thought ear plugs might be overkill for short trips. I spent this afternoon rejetting the carb and shimmed the needle, and I must say it definitely made a noticeable difference. However it also seems to have quited the exhaust a little bit, it seems to have a much lower rumble to it now compared to yesterday after I installed the exhaust...is this normal? Or maybe it just made me more deaf yesterday so now I'm not noticing it so much anymore For my longer rides I think I will still be sporting ear plugs, and you'll also want to note that I wear a full face helmet too if that gives you any kind of an idea as to the noise level.

But it definitely sounds bad @$$ when I crack the throttle open now : D

Yes the exhaust may sound quieter when you did the jetting (richened the mixture). A rich mixture exhaust note sounds 'fat' - a description might be lower, deeper tones. A leaner condition has more of a sharp 'crackle' sound to it.

A full face helmet, especially with the Blast exhaust exiting right below your ears, actually can act as an echo chamber, trapping and collecting the noise from below.

I wished I remembered to ask you to measure the diameter of the pipe before you wrapped it. Is it still 1 5/8" or is it now 1 3/4"?

actually I think it's 1 1/2" if I remember correctly, I measured it when I ran to napa to get some steel hose clamps to hold the wrap, those cheap steel zip tie thingies DEI sold me sucked! With the wrap and the silicone spray it measures 1.72" right now, and measuring the thickness of the wrap I have left over it measures 0.038", so if you subtract the wrap thickness from the wrapped pipe thickness twice you get 1.644", and keeping in mind the fact that the unpainted wrap I measured is probly a little squishier than the stuff on my header I think 1 1/2" is right

I also made sure to measure between the overlaps in the wrap, so there should have only been one layer of wrap on each side of the pipe when I measured.

Leaner fuel mixtures burn faster, making a sharper sound. Richer mixtures burn more slowly, providing a deeper sound.
