    It is very close to 1-3/4... I used a stainless 1-3/4 mandrel bend lead pipe to connect to the OEM head pipe.



    I suppose I should post this here:

    Supertrapp IDS2 quiet core muffler. Custom fabricated stainless conecting pipe.

    clearly marked forest approved
    rebuildable
    tunable by adding/removing disks
    cool sound
    no cat - runs cooler
    can be purchased as a "universal" muffler, mounting tab and emblem are included but not mounted from the factory
    a tad smaller than OEM...

    Shawn, were you pounding in fence posts with the stock pipe? :eek1

    No one will ever accuse you of pampering your X. It looks great!

    Ok, after seeing the damage Shawn did with the aftermarket Exhaust, I decided to finally do my Stock exhaust core test......

    Instead of hacking the end cap off, I thought it might be easier to make a small incision under the end cap to allow the saw-zall blade enough room to
    saw the witches snout off:lol3

    [​IMG]

    Add Saw-zall with Lazer blade........

    [​IMG]

    Once you get a nice straight line started, it happens pretty quick.....

    [​IMG]

    Now its time to snip the snout off by inserting the saw zall blade into our nice clean slot.....

    [​IMG]

    The Key is to start slowly and watch the throw of the blade in the saw. If your not carefull, you'll bang the top of the cone up by whacking it with the blade tip. Fortunately for me, I'm a saw-zal master and made a nice clean cut:lol3

    Now we drag out the big hardware to burn a hole in the muffler, so we can remove the inner core.....:eek1

    [​IMG]

    The hole saw is a 1 7/8" with the pilot bit removed. If you use the lower part of the tail pipe(big tail pipe) as a guide you can start the hole on the top first and then pivot the hole saw down to finish the hole. Trying to start the hole saw square is impossible.... it will walk all over the place!

    [​IMG]


    If you're carefull and take your time, it should look like this....

    [​IMG]


    :clap

    This is what you'll pull out.......

    This is the pic from my old beat up test exhaust, but its the same idea.


    Results of the test.....

    Sound is much better and more thumper like without being obnoxious and Harley like. It actually reminds me of what my 2000 640 ADV sounded like after I did the Creeper core mod. I took her down the road and noticed a HUGE improvement in throttle responds and down low power. I was back to roll on wheelies from a rolling start:lol3

    Thank you for tuning in to Cranky core 5000:deal

    Yo Crankster,

    what does this get you? A bit more flow and a better tone?

    The cat is still in there and it's still mega hot?

    I have the Remus Freeride. But I took it off and put the stocker back on. I can't stand everyone turning from a block and a half down to see what is coming roaring down the road and it's just me on my lil beemer.. :lol3 I like stealth. How am I supposed to get a good shot off when everyone hears and sees me coming? :gun2

    I will say that just from my "arm scale" that the stocker has about 10lbs on the Remus. I'd like the Remus if it just wasn't so effing loud!

    Have you had any thoughts about continuing your surgery to remove the cat from this thing? I remember people doing that on the KTM 950 silencers.

    Thanks for the pics. And from one sawzall-master to another... it's all about the sensitive trigger finger. :deal

    The main reason why I wanted to core the stocker is so I can keep the cat.
    I can't stand the raw unburnt fuel smell..... it makes me sick:puke1
    If weight was a major concern for me, I would lose 10 pounds and use the Remus cash on a gym membership. The Remus is lighter, but its also useless as a muffler and the sound is terrible. Way to raspy and no real grunt IMHO:deal If I took the cat out, it would be just another chambered muffler.... LOUD.

    Coring the stocker gave it a deeper tone and much better throttle response. It also allowed me to keep $600-800 in my bank account so I can buy fuel and tires:lol3

    Yup, Trigger finger is important.... Don't need to go rushing into the cut like John Wayne. Thats pretty much true in Life in general:rofl

    I just installed the Scorpion pipe on my Country and love the changein power. I clutched up a third gear wheelie the first time out on it.

    This pipe runs WAY cooler than the stocker, and breaths much freer (sp).
    I have removed the airbox cover and replaced the stock air filter with a foam one from BMWAtlanta and the difference over stock is very noticable.

    The only drawback?

    It's insanely loud!!!!!!!!

    Bike runs real good with the supertrap. I do notice more power/throttle response but I cleaned the twin-air filter and swapped in the 15t sprocket (from 14t) at the same time. It is not really an apples to apples comparison.

    and it sounds great! Not too loud, nice low thump. Rode with a DRZ400 and an XR650L on sunday, both bikes with full titanium exhaust systems. Both guys commented how great the X sounded. Was a bit quieter than the DRZ, a tad louder than the XR.


    That is what an east coast enduro circuit will do to your bike... Good fun!

    Hi,

    Looking for a quiet (we're losing trails here), E-marked (street legal in EU) silencer for the XChallenge, but with no Cat - I go to places where there's only leaded petrol.

    One option is the Akrapovic from BMW. The excellent parts fiche at Max BMW's site lists two versions. Can anyone confirm if which of the two are street legal and which of the two have a cat?

    Thanks.

    Yes the REMUS is loud :evil

    It really feels like the machine has transformed though.

    Maybe a db-killer would fit.... Has anybody tried?

    Okay, I understand the Remus Freeride is loud. Anybody figure out a way to tame it?

    I have the Titanium slip-on on the way from another inmate, and I want to be a good neighbour.

    Good point for the torque at low revs! The pipe looks great, Nice heat protection.
    But way too expensive...

    If the Akrapovic is quiet and reasonably priced, I'd get it just to get rid of the weight and heat generated by the cat. But the price that I got from my dealer for the BMW supplied Akrapovic slip on only was around US$1400 :eek1

    Did I miss a review of the new Staintune slip on? How's the sound on it? :ear Still looking for a quiet slip on. :(:

    I think my setup is perfect, not loud at all with the sparky, cheap and looks great!! You just need to find someone to fab the pipe on for you. I also feel as though the power diff. is rather large, it is way more crisp with the throttle response. More pics and details on the link below.

    Rick, I just had a buddy make a decibel dog insert for my Scorpion ($400) exhaust and it's taken some of the high RPM thunder out.
    It still growls pretty loud on start up..........

    It Barks louder than stock but not offensively until you wind it up over 5000rpm. Improves power delivery and removes heat from CAT. Around town it's only marginally louder than stock. Cost $640Aud and easy to fit.
