    Inquiring Inmates want to know... so I duly sacrificed and put my pipe to the band-saw for the sake of furthering our knowledge base:
    [​IMG]

    As we can see, it is mostly hollow inside with only very few pieces of metal acting as supports more than baffles... No packing material at all, just a pipe going through the middle with holes in it. I suspect the shape of it acts to dampen the noise before it exits the pipe.

    Amazing if you really think about it... a big empty cavity dampening noise rather than amplifying sound waves.

    (Ok... I didn't really cut up my pipe. This photo credit properly belongs to 'VtStrom' in the DRRiders.com group.)

    Yep I fitted one. It really livened up the old stock engine, stock carb set up I had. Big difference, especially down low.
    I have since added the mxrob carb mod and opened up the air box. This bike is really responsive and alive now.

    The stain tune pipe fitted perfectly, (as did the stain tune I put on my other bike, WR250F) , very simple to fit.

    They are a great pipe, all stainless, quite light, no rivets or screws holding them together, look like they will last forever.

    They also have a nice note without being offensive, though they are definitely louder.

    Well fellow asylumees, today I ran across on a 35F01 can and snagged it. :lol3

    Any thoughts on the merits of the Hindle mid-pipe as opposed to 2-brothers?

    Hiya Basketcase :beer

    After the Hindle wears its way thru the brake line clip, it starts working on the brake line itself. I read somewhere that they're working on a revision. So I never installed the Hindle I had bought and went with Kientec's 2-brothers.

    It all started here and ran for several days. A Hindle rep signed up, asked some questions and disappeared. It was later someone said they were working on redoing it.

    ER70S-2, thanks.

    After re-reading all this and thinking on the photos you posted I think I'll just go with the 2-bros and save myself the anxiety.

    Ordered the 2 bros pipe today from Jesse. I'll try and remember to do photos for a write up of the install.

    I have had the 35, 40, and 24F0 cans on my DR, with the air box/jetting mods... I would be happy with any of them; the difference, in a nutshell:

    40f0; 4.5#, sounds better, flows a LOT of air

    35fo; approx 7#, same size as the 40, still sounds great

    24F0; same weight as the 35, slightly longer, my DR seems to like this one the best, has the perfect amount of restriction.

    I have a pumper carb and oversized header on the way from Kientech.com; interested in how the different header will affect my torque, should know by the end of the week.

    Allright Guys! I have recently picked up an '04 and have proceeded to strip it down and clean it up, (in my living room, no less) anyways, I was hoping that some asylum guru here can identify the pipe on this bike there is no markings (that I can see) maybe this is long shot, but I thought if anybody would know, it would be you guys! Thanks

    Hard to see, but there are about 5 deflector plates.

    Anybody ever mount up the 24F0A using a flexible exhaust pipe from auto zone, pep boy, etc? I scored a muffler for $15 but don't feel like shelling out $220 for a mid pipe..
