I'm going to take a stab at making some pipes for my 08xl and need some inspiration, I've got an idea and seen a few i dig but i need more pics. Help me out if you can. Thanks everyone.

Look here for a bunch of sporties: PHOTODUMP (http://www.chopcult.com/photos.php)

Mounting is going to be the thing to pay attention to, if it's like my FXR, you'll have to mount everything to the engine and trans so the exhaust doesn't stress from mounting to the moving unit and the frame.

Yup,rubber mounted motors can be tricky. if you choose to mount to the frame,give the pipes the ability to slide back & forth. Take a look at a twin cam,they (the ones I looked at) have the rear pipe mounts on kind of a rail.

I broke my rear exhaust studs off in the Smoky Mountains a few months back....you don't want that kind of trouble!

I'm not sure how your sporty does it stock but there is a pre-1992 FXR mount that is a rubber isolator that could be repurposed to attach to the frame and pipes and still allow some wiggle room.

rubbermounted engine = rubbermounted pipes. fun, ain't it....

I've alread peeped the photodump, not too many rubber mounts. and it is the mounting that is most problematic. My previous set up was a modified set of stock head pipes and no mounting other than the flange studs. It lasted about 5k befor the front cylinder pipe broke off on my way to work on monday. Thankfully i was only about a mile from home. My plan is to bring them together to utilize the stock rear cylinder pipe mount, but i like the look of having them tucked up higher with the front pipe running under the air cleaner.

If pipes are tied together near the end will that provide enough support to prevent breakage without mounting to the motor?

Do it, and then we'll know.

I'd find a bolt hole and make a brace,there's plenty to chose from.

I did a reasonably short two-into-one high pipe last year on a 98 with no supports other than the headbolts and it held up fine. It was a pretty lightweight system though with no baffles or heavy muffler. Also didn't shake as much as a rubber mount though. I would think you could come off of several place on the trans end of the motor (sprocket cover) or something like that and make it pretty solid. Good luck, let us know what you end up doing.

Like Bill said earlier, there's a way to use rubber isolators or any sort of rubber bushing to help with the mounting. So if you make a brace to connect to your frame, you just need to have the pipes connected to the rubber piece and then the rubber piece connected to the frame.

Its not exactly the same, but alot of the Eames designed chairs from the 50's use rubber shockmounts to allow the backrests of the chairs to have some flex from the back supports.

Remember the rubber mounted engine moves a LOT. It's not just a motor that vibrates a ton. Look at what HD does on the big bikes,there's a ton of room for the pipes to move back & forth. A rubber isolator will more than likely not have enough flex and will tear. Your not trying to take out vibration,it's actual movement that you have to consider. I've done numerous pipes on rubber mounted sporties,they can be a pain.

What Bill was saying is also a good idea,light wall tube,no baffles,and maybe you'll get away with it. Again,I'd find a bolt hole and use it for a solid brace,no rubber bushings.

yea id fab a bracket to attach to the engine/tranny - obviously you cant copy the big twin exactyl, but use that idea - my bassani has a beefy ass bracket that mounts to the tranny case on my dyna so it 'floats' with the motor assy - over big bumps you can feel it hit the underside of my midcontrol perch - if this didnt happen it would be seriously stressing welds/exhaust flange studs - even with that - Ive snapped a xst stud from smacking the end of the pipe on an offcamber turn - you dont want to do this..trust me.

I rocked the stock header pipes sans mufflers and without brackets on my 07 rubber mount for almost 2 years with no issues. But they are pretty light and short!

The ones above that I made are mounted together near the ends with an aluminum brace. That setup is bulletproof. Those pipes are made out 16 gage 304 stainless and have 304 stainless baffles inside so they are pretty lightweight, but even with a little more weight I still think that just tying the two together is the way to go. They are for sale in the classifieds if your interested. If you have any more questions let me know.

Im not sure I would go that close to the oil tank with those pipes... the oil on the rubbermounts is already pushing it in the hot department.

I never had any issues with them there. Most peoples oil temp runs high because of running lean.

Here are some pics of the mock up.
http://www.chopcult.com/uploads_user/1000/435/5257.jpg
I have done the finish welding (forgot pics), put in the O2 bungs, made mounting brackets, and test rode.
I spent some free time yesterday with a flap disc in my hand smoothing welds out, I'm super stoked at how well they came out, not only looks, but the sportie runs awesome with them on it.
Now i need some more advice... Baffels or no baffels? they sound awesome as is, loud as hell and throaty... but they sound like a drie by shooting on deceleration. What do you guys do?

Leave 'em loud man....why would you want to make them all quiet????? especially if it runs good, you won't need the m for the back pressure right?

I had short straight pipes on two Sportsters: a stock 99 883 and a slightly modded 96 1200. My local H-D specialist recommended inversion cones at the cylinder with both bikes, and they ran and sounded great. I gave baffles a try on the 1200, but the sounded shitty.

BTW, your pipes look great. Have you considered taking off the countershaft cover and using one of the bolt holes on this part of the motor to hold a tab for the end of the pipes?

I ordered some torque cones, should show up early next week. I need to take some more pics, but I used the rear most bolt to support the lower pipe and the two pipes mount together towards the top of the rear pipe. Hopefully this provides enough support.

I've ordered a set of Bassani Pro-Streets and the dude highly recommended torque cones ... spent about 15 minutes on the phone explaining the theory ... he was a little long winded, lol. Good to hear they actually work. I think you nailed it on the design of those.

Thanks man, I cant take credit for the design, they are made to look like a set of pipes that ledsled sells only not as tucked up, so i could use the mounting point i wanted.

power/torque cones are a joke. the pipes on the other hand look killer. good job on them!

Those look good. Youll love the fact that you can actually turn right without dragging the exhaust.

Here they are finished (going to ride them for a week or two to check durability then wrap em up).

Slim makes some cool shit. Just bought his 05 rubbermount. Its the blue 883 in the photodump with the high pipes check his blog for his info and what not. www.slimsfab.blogspot.com

Those are nice! You could also check over at Nash M C, Taber has a new set of pipes out that will fit any sporty. Same style as the #9 or the Slugger.

here is the set i made, i used a V&H bracket along with a homemade bracket that bracketed to the V&H bracket (what the fuck i guess i used alota brackets haha) so i wouldn't run into the stress issue, i'm currently runnin these but lookin for an excuse to pull them off and make another set. guess i gotta come across a little $$ too.

anyway, these have been on my bike for around 2.5 years and have not had an issue as of yet

you can see the V&H bracket pritty good in the first and the other one i made in the second, these pics are way old but for the pipes you can get the gist
