Agreed, looking very nice.

One of the things I really like about Kevin's can is the smooth, seamless design.
Rolled seams are a no good for me.
I expect the system I have now to last Loretta's lifetime.

I also don't have plans on fairing lowers and/or a bellypan.

Dean - I have 3 half-meg shots of the race pipes if you're interested.

Thanks for the

At this point, it's really more of an exercise to prove to myself that I can do it and show a definable gain in hp/torque.
I'm not sure how I'll end up getting this polished yet. I think we've got a bench buffer and a few grades of rouge at work. I'll have to get one myself eventually. I used just a tiny bit of never-dull on it, but the metal is still too coarse to make it shine like what I want. The muffler itself is supposed to be a near mirror finish, just haven't ordered it yet, so again, we'll see when it gets here.

Zac, maybe later when I look into doing the headers, but for now I'm just doing from the collector back. I've seen the small pic that was posted here a while back, but that's all. Speaking of the race pipe, does anyone know what the OD and wall thickness is on the race headers? I'm just curious. Doing a full system will most likely be out of my reach for quite some time.

This is more like what I was thinking of originally, just not the straight through design. Seamless design, fully welded and stainless steel all the way through. I know for sure the center/offset one is not straight through, I've got one on my truck, but it's not polished.
So now it's, do I go with a 4x9, a 5x8, 5" or 6" round, offset on both sides, or center/offset? I have soooooo many options at this point. The brackets to hold it up will have to be machined to fit anyway, so at this point it don't really matter a whole lot which way I go as far as how it's held up.

Dean, you're on the right track I believe. One of the things I became aware of pretty quick was ground clearance using a turbo type of muffler and fitting it under my fairing lowers. I ended up with some careful measuring, and used a 3 1/4" deep by 7" wide and only 13" overall length. Even then I had to keep it up as high against the bottom of the engine as I could and the reason for my dimpling of the muffler in certain places. There was a couple of things protruding out from the bottom of the engine. And I believe a bigger issue is to keep it centered under the engine for clearance while laying over in turns, maintaining "mass centralization" also.

I know you probably will not get lowers and the reason for using the SS for looks but try your best to keep good ground clearance. I just do not care for those units angling out the back like UJM's.

One last thing: I believe the turbo type of mufflers are the closest units to the stocker, with better sound, and slightly better flow, and I have not had to do any fuel adjusting YET even with a K&N. Maybe later for a little more performance. I just don't know if I need more. My bikes running great. A little different here at altitude though.

Please continue, you're doing great! Bob

Dean, I love magnaflow sound and design. I have their exhaust on my Grand National and SS. I prefer magnaflow for the deep throaty growl, and lack of droning like the flow master. I had looked around on their website a couple of months ago. I wonder if we could use my mid pipe for the D&D and attach one of these to it? I really like what you are doing with your design. And from hearing you explain it on the phone I think it's going to be a great setup. I'm still waiting on some more stocker info before we can go that route... if you manage to come up with a sweet design on your project and I can hear/see it in person. I might try and sweet talk you for another with some helpful cash. : )

Dean, here's a picture of the mid pipe... I don't think it's near the size of the one you are building. I don't have any mics to pop around it.

Mmmm, probably 15 lbs total for this one because of the wall thickness of the tubing I bought. The shipped weight for the tubing was 10 lbs, but I'll be removing about 1/3 of the material. Not sure on the weight of the muffler itself, never actually checked. The stock can is 21.5 lbs. As I recall, the Jardine was about 9.5 lbs for the CF version. I'm not worried about weight loss so much as sound/clearance/looks. If I drop weight in the process, so much the better.

I think the D&D pipe uses a 2" midpipe, so with a smaller ID muffler, yeah, it would probably work, just the flow characteristics would be a little different. I won't know until I actually get this finished and tested. I think the muffler is rated at 700-800 cfm, so it should be plenty on the 2.5" one I'm making.

Hi, I'm new here and seriously considering a 1125R. If and when i do get one I will be certainly looking for an aftermarket exhaust. I'm sure you're trying to keep the cost down but have you considered of these for you collector.

Yep, looked at burns stainless. Kinda pricey for what I wanted. If they had a U-J bent pipe, I would have ordered from them to get it all in one place. As it is, the collector I made is a wee bit less than theirs. Time on this project that I spend right now is "free labor" because I want it done and done by me.
One other problem was the spacing on the collector. The 1125 (mine anyway) has around 3/8" and 1/2" between the intake side of the collector. The one pictured from burns is almost zero. Sure, I could have special ordered it, but again, I want to actually build this myself and do it for the least amount of $$ possible.

Btw, I made that table for about $20 in 1-1/4" angle iron and 16 guage sheet metal. Stick welded the frame, then tig welded the sheet metal all the way around on the top. I just tacked the bottom in about 10 places to hold it. I'm wanting to add wheels to it, just haven't found any yet.

is there a reason why it could just not be a pipe without a mufler. I want my bike to be loud so the old people in the road hear me coming or the guy with the earphones while driving can still hear me!!

If that is what you need to be happy...you need the D&D...friggin thing is a megaphone muffler (oxymoron intended).

Did about 10 minutes of buffing on the collector tonite.

Buffing wheel only, larger pipe is untouched





Close side with simichrome after buffing





Comparison, raw pipe to light polish





Incentive to continue on the left
I'll probably get some filler rod and blend the weld some more.

I'm jealous, I can see you're having way too much fun.

When you're done, you'll have a unique and good looking exhaust.

Well, I'm not 100% sure on the muffler size now. I measured the stock can and it's about 8" across, so thats my limit for width. Height is debatable, between 4-8" max, depending on where you measure. I gotta look for the site that had build it yourself cans now. Nothing is the exact shape/configuration that I want. Grrrrr. I did see a 3.5"x7"x11" can from Magnaflow, but it only had 2" internals, so it won't work for what I want. If it were 2.5", I'd buy 2 or 3 just for the fun of it.

Thanks for the votes of confidence on this, at least I know I'm making good progress by other people's reactions to it. Just wish I had unlimited funds to play with to do it like I want. O well, cheap is good.

Dean, I saw the sizes as you have on most turbo type mufflers but I could stay with just plain steel ones being behind my lowers and the reason I went to a smaller one as you looked at. My collector is only 2 1/4" and the Walker I used has just under that internals and has had plenty enough flow for every thing except all out racing which I will never do. Just occasional track days at Miller.

I like your "build it yourself" even on the muffler. Great idea! Would you care to share that website with us? I might just do that for a winter project to get a better shape to fit under the engine using the internals from a spare turbo muffler I have.

Still got enough beer on hand? LOL Have fun. Bob

The site I found has either 3.5"x8" oval or 4"x8" oval cans, as well as different size round ones. I'll go with the 3.5x8 just to make it smaller. It's got options for end caps (dual, center or offset) internal stuff (spiral louvered pipe, although I'd prefer perforated) as well as stainless steel wool for packing. The body is polished 304 SS in 12" lengths, which can be trimmed down to whatever size I want, probably going to trim 2" off for a 10" can. 3.5x8x10 should do the trick. I think they even had internal baffles for supporting the tubing, so I can possibly go with the 3 chamber design I wanted. It will probably cost a bit more this way ($150ish) for the muffler, but I'll end up with exactly what I want, not what someone else thinks I want.

Bob, I don't have the site link handy but I'll find it tonite when I get home. I think it was coneeng.com or something like that. They sell Megs collectors and various other fabrication parts for doing exhaust. The price list on individual parts was very reasonable. I think the internal tubes (spiral louver cut) were only about $11 each. Of course, all of it adds up when you build it, but I think it will be worth it in the long run.

I'm still not sure why all the big mfg's charge so much for these aftermarket pipes. Sure, there's a little bit of work sorting out the performance of it and then setup work once thats done, but still, $600+ for a 3 foot long, straight through pipe? Pfffffft! I'm still not seeing it. What did it cost you to do yours? $300? Less?

Actually Dean, it cost me about $100.00 in parts. The Walker muffler was only $25.00 and various mild steel exhaust tubing bends was the rest. Some flat bar stock for hangers from Home Depot about $10.00.

An unimaginable amount of time. Probably in excess of 30 actual hours of fab./welding time. A lot of measuring three times, cutting, tacking and trying. Then redoing until just right. I lost track as I was having fun doing it that late fall/winter.

I would not want to do it for a living though. Rather be riding. Sunday looks good here and I'll be "in the wind" Bob

Sorry, but the Jardine is long gone, the $300 from that went toward the Miller tig/stick welder.
Honestly, it was just a little bit too harsh for me. I want a good rumble, not a really sharp bark from the pipe. Every time I fired it up it sounded like a small explosion and would almost always make the wife jump from the way it hit that first note. I know she hated it and eventually I got to the same point of not really liking what I heard. If you're wanting to be heard, D&D or Jardine is definitely the way to go. Mine could be clearly heard from over a mile away in a jeep running down the road at 70 mph with the windows down as I gave it a full run up over the speed limit. Had a buddy following in his jeep and he was listening for it the whole time. Nothing else was out there, so no extra noises to interfere with it.

I'm not worried in how it sounds, just like a little more performance...though I must say I walked away from all of the bikes at a track day being stock. It is surely a fun toy!

Dean, I got into Las Cruces, NM for the night. I will be in and out of here as we are doing some serious testing for the next few days. I think you are really on to something! I can't wait to see what you come up with. When I get back to STL I'll see if we can link up and maybe just do some outlet mods on my stocker for the time being. Still no word on the "info" I requested. Thanks!
