Slip on undertail?
How does that work?

scotty · October 25th, 2010, 01:57 PM

It cant just be a slip on. Spam?

want1sobad · October 25th, 2010, 02:05 PM

interesting that there hasn't been a response from the op........

Ninja250under · October 25th, 2010, 05:02 PM

We i me and a few friends and my dad. How the slip on works is instead of putting on the canister you will slip-on a section of three different pipes and an then a canister.Were hoping to finish the prototype in about three weeks and have pictures up. The reason i haven't answered is because i was in school and then i had football then i had to go for a ride!

scotty · October 25th, 2010, 05:03 PM

Pics asap! What type of muffler are you going to use?

Ninja250under · October 25th, 2010, 05:10 PM

Thats the thing my dad own's a sound and muffler shop! when the bike i started searching for an undertail and could't find any.And my dad has plenty of supply's to make one so once we make it were it works good were going to start makeing them for the public.

want1sobad · October 25th, 2010, 05:12 PM

kewl! looking forward to pics

Ninja250under · October 25th, 2010, 05:18 PM

OK ill get them up as soon as i can. Right now i'm looking for the right kind of aluminum then we will start.

saw something like this on 2fiidy.com

Ninja250under · October 25th, 2010, 06:45 PM

Thats kindof what were going for. Buy ours isn't going to be over price like there's ($$800). And for some reason they decided not to make them anymore.

ChaosFromAbove · October 25th, 2010, 08:09 PM

let me know if u need any product testers =]

randomwalk101 · October 26th, 2010, 06:26 AM

what? what? no pic??? It didn't happen

edwinmcq · October 26th, 2010, 06:43 AM

I saw something likes this about a year ago. It looks great. My concern would be heat.

ztrack157 · October 26th, 2010, 02:52 PM

Been working on one of these for awhile. The can doesn't get hot the header does. Had to wrap it in thermotec.

JMcDonald · October 26th, 2010, 03:06 PM

Yeah i was gonna say heat shouldnt be such an issue it cant easily be overcome. But im exxited to see it!

I can see that making a huge problem but I think we have a idea to stop it. It may take a while to before I get any pictures up but we will just have to wait and see

austexjg · October 26th, 2010, 04:40 PM

At least keep us posted on the progress...

ChaosFromAbove · October 26th, 2010, 04:43 PM

i'm willing to melt my bike for it...need new fairings anyways lol

I worked on a patent case a few years ago involving a product called Insoflex [sig.] or Insuflex...something like that.

It was a pipe covering that came in varying strengths that was designed to shield heat from various types of industrial pipes. You should see if you can find something like that.

JMcDonald · October 26th, 2010, 07:52 PM

I really don't think it would be too difficult. I swear I've seen people touch fiberglas-wraped turbo headers after hard runs when their surface temps would otherwise be like 1200+ degrees. Mufflers (especially on an NA 250cc engine) won't get anywhere near that hot (a few hundred degrees), so shielding them shouldn't be a big deal at all. Whether it is a couple layers of fiberglas or a few pieces of sheet metal clamped over the top of the muffler, a simple solution should exist.

Ninja250under · October 26th, 2010, 07:58 PM

I agree I shouldn't be to hard I have a plan but it will mak the muffler about half an inch taller. But the main concern was the pipe and now I think we've got that covered

headshrink · October 26th, 2010, 11:48 PM

I love the look of these, but I assume they won't do anything for performance.... I would think that all that extra pipe = more back-pressure.

camaroz1985 · October 27th, 2010, 07:31 AM

For heat shielding look into Carbon-X. You can get it in fabric form, and apply it to any surfaces you want to protect. We have used it on carbon fiber race car parts (chassis and suspension), works great. As a test we covered our hands with it and held it to a propane torch and didn't get burned. It is kind of pricey, but works well.

Ninja250under · October 27th, 2010, 06:06 PM

Thanks for the advice I think that would be the a good choice for us I just don't want to have the rep. Of burning peoples ninjas.

Nemesis · October 27th, 2010, 09:12 PM

Aluminum pipe? Makes more sense to use stainless like the rest of the system.

edwinmcq · October 28th, 2010, 12:58 PM

Soooo, let's go back to the first couple of posts. Where are the pics?

maybe he intends to use the aluminum as a heat shield?

Ninja250under · October 28th, 2010, 01:26 PM

I probaly will use stainless. The pics arnt sure when they will come. Probaly sunday night is when we think we will finish the pipe. And not until the week after that will the muffler be made but could be sooner. I know that we will start selling them the week after we finish the prototype If all goes well

MikeCG23 · October 28th, 2010, 02:02 PM

I'm interested in seeing the final product!!

headshrink · October 28th, 2010, 02:23 PM

Giving the benefit of the doubt one more day before cutting off the food supply.

Ninja250under · October 28th, 2010, 06:03 PM

Ok the final product won't be here till at next week I bought the cutting tools yesterday and a welder with wire today. I just now got done putting them in my little shop. Now we will buy the pipe Saturday. Then we will make the pipe Sunday. Then muffler next week but.

But does anyone know a shop to buy a aluminum so we can make the muffler
