    There have been a number of conversations about KTM LC4 exhaust systems and slip-ons, so I did a little research (very little) and came up with a few lesser known brands, at least in the US, to consider besides the factory KTM stuff, the Supertrapp IDS2, Big Gun and the on again off again Pro Circuit T-4.
    So far here is a short list of some of the other brands:
    Sebring, BSM by ABP, Leovince X-3, SP, Doma, Akrapovic. I'm sure there are others out there, but I haven't found them... yet.

    The first link is the main page for Schnider Cycles in Germany, the second for their english power parts pull down menus. The third is for ABP and is in german.

    http://www.schneidercycles.de/

    http://www.ktmax.de/indexa.htm

    http://www.abp-racing.de/

    My thoughts on this whole pipe thing is that there are lots of styles, materials, price ranges etc, but I doubt any of them, within a given sound db range, offer any dramatic improvement over one another. So go with exclusivity, features, finish, quality, performance, sound, price... what ever your priorities are.

    I personally went with a Supertrapp IDS2 because of the quality, price, USFS spark arrestor, the ability to fit it ( with a minor modification) to my '03 Adventure and the wide range of tunability, and as I am a friend of a Parts Unlimited dealer... easy to get.

    Ciao,

    Interesting. The can looks a bit basic but I like the tappered megaphone leading up to it. It appears they start at $350 for a pipe and muffler, although in the "testimonials" I didn't see any reference to KTMs. I sent Bob Murray, the owner a e-mail; maybe we'll hear back soon. So, possibly, there is another one:

    Thanks Ram600,

    I went with the G-Force Titanium exhaust. Check out:

    http://www.solidcorporation.com

    John is the US distributor and importer of G-force. Gave my
    '03 640 Adventure a big throaty sound, not too noisy but
    woke up that motor and made it sound as it should.

    imho, Supertrapp has had the edge for just about anything for at least the last thirty some years.
    consider all the other options who's been around the longest with the best prices and tunability out of any other pipe. Supertrapp.
    the fact that their also USFS Approved spark arrestors is only a benefit to Enduro/adventure bikes doesn't mean their just for that.
    Had one on my Z1 years ago and loved it then as now, have one on my Lc4 today. next bike I get will also get a Trapp.
    can't be beat by a $500-1000 pipes for around $200/250 bucks. . :thumbup

    Ah! This is starting to look like a pretty good list of LC4 exhausts!

    Mack, your system is VERY nice, but what brand is it? I'm afraid I can't read the emblems.

    Gaz, thanks very much. Completely forgot about Staintune, had one on my Buell. For others that forgot and are interested, here is the link to the US importer:
    http://www.cbtimports.com/

    DJMARLEY, I see that you have to call for information. Is the G-force something they have to make up, or do they have a standard part number for the LC4? Good looking mufflers!

    Thanks everyone for the input, keep 'em coming :thumb

    Creeper, sadly it's not mine, as there are no motards in my garage. Love those pipes though, I had an interest in getting a set for my ADV, but it was hard to get info, (not that I tried that hard) and with my Touratech racks I was concerned over fitment issues, not to mention weight. If it works anything like the 1 into 2 systems on the Duke II and Rallye, it should sound and perform as well as it looks. Cheers, Mack

    Thanks Mack,
    The Sebring LC4 slip-on mufflers are sold thru both ABP & Schneider Cycles in Gemany (the links are above, on my first post).
    I tried to locate a vendor in the US, but all I found was what appears to be a auto exhaust distributor in Hamilton, Ontario Canada. They have no web address that I can see so anyone interested will have to call, write or e-mail for information. The Sebring site itself is very interesting!

    So, this is what we have so far in no paticular order:

    Factory KTM
    Supertrapp
    Sebring
    BSM by ABP
    Leovince X-3
    Staintune
    SP
    Doma
    Thunder Alley
    Akrapovic
    G-Force
    Big Gun
    Pro Circuit (maybe)

    Thanks everyone for your input. I think present and future LC4 owners will benefit from having a fairly current list of what is available to them.

    In our next episode, we will see what folks are using as a replacement carb for LC4s. From what I've seen and from personal experience, the most recent street legal carb, the Mikuni BST 40, works fine on the street and OK to poor on dirt and is not the most responsive mixer in the world.
    I recently obtained a Mikuni TM (HSR) 42-6 that I will be screwing around with, when I have more hard data/photos, I will post it.

    Thanks again to everyone!
    Anyone reading this, if you have a exhaust not already on the above list, don't hesitate to add your information.

    Thanks!:thumb

    Funny how everyone has info on the Sebring systems... but no one actually has one on their bike. It's too bad, as they look like a well made piece of kit. :cry

    Thanks for the details rapiti :thumb

    I recently recieved a nice reply from Bob Murray of Thunder Header. the transcript is below:

    Hi Bob,

    Just doing a little research. Do you have, or have you made a slip-on muffler or a complete system for the KTM LC4 series?

    Thanks for any info you can provide,
    Creeper


    Creeper, thanks for your interest. As of this time I have not made a system for the LC4. I have had some interest in systems for the adventure model but have not been able to secure one for a prototype. Which bike were you interested in? If I know the specific model I can track one down and build a system.
    Thanks,
    Bob


    So, there you go,
    Creeper

    hy I like my stock one because its quiet and I get killer fuel mileage which comes in handy on those long/I think im lost mountain roads but anyway ktm makes great slip on and the price is getting better after my rally fender (if it ever gets here )im going to consider the akrapovic that's what they use in the Dakar so its got to be good ...Dan

    Is it possible to get exhausts like the 660 ralle uses? They look awsome, dont know how practical they would be.
