  • GSXR / GSXF Slip on Conversion Project.

    If you've been in the "Katana Talk" forum, "Where do you get a cheap slip on?", I made reference to an E-Bay find that I've been able to use for my 750 Kat.

    The GSXR muffler that I found on E-Bay is made by "Hurric Exhaust Systems"


    I bought it for $225.00 cdn. Tax and freight inc. fron AltlierMotorsports. Que. Brand new in a box, clamp and decal included.
    Follow link below.

    A GSXR muffler uses an adapter or flange to fasten itself to the mid pipe before the header.

    I had this one made from stainless steel tubing from a friend of mine for $50.00 cdn.

    The outside dimension of the pipe in 2.25 " with 2.5" out of each end.
    I had him hone the inside if the adapter to falicitate easier installation.


    I had the mid pipe fabricated by a friend at the local midas muffler shop. It only took about 45 minutes to fabricate and make ready for paint and installation.


    I purchased a can of "Plastic-coat" HP 11, high temp (1800 f) paint.
    I cleaned the surface of the mid pipe with laquer thinner then I used 500grit paper and finally steel wool to clean the surface.
    The directions on the can of paint instruct, 2 good coats of paint (without primer) and allow 1 hour to cure.
    After the hour place in non- cooking oven @ 650 f or run engine at temperature for 1 hr.
    Once cthe pipe has cooled enough to touch, use a clean cotton cloth, and polish the pipe to a "Black Chrome" like shine.


    Use anti-seize compound when installing mid pipe into header and when installing adapter to the mid pipe as well.
    Don't forget to have the adapter positioned correctly so that when the muffler is installed, the tip will be pointing in the right direction.
    Also use Loc-tite on the muffler bolts.


    Be sure to test fit everything a couple of times before final installation.
    Now that it's complete....
    The bikes performance is noticably enhanced. Second gear wheelies come very easy.
    The original pipe can be installed in a few moments when the wife and I want to go on a longer trip or weekend get away.
    And no extra mounting hardware was needed.
    It sounds very deep at idle through 6000 rpm. Once it hits 7000rpm it screams. Almost to the piont of hurting your ears. 10500 rpm makes it sound like a GP bike. (I had to try it a couple of times.)

    What do you think?


    Grand total $275.00 canadian.

    I think it looks pretty awesome, I don't suppose there's any chance of a sound clip?

    Is it D&D loud at high revs? or even louder?

      ...sounds like...

      I'm going out with some friends tonight.
      I hope we'll get a sound clip then.

      It's very comparable to a D&D only it pierces the ears.

      It makes me behave badly...
      ...in a squidly sort of way.

        i don't think it was a good idea to skip the midpipe hanger/bolt. the 'can' clamp isn't really that strong and lets the pipe vibrate a bit. without the midpipe bolt all the forces ( weight & torque/flex ) is placed on the header flanges.

        i'd keep an eye out for stress cracks.

          Stressed out

          I really fought with myself over that.
          I'm going to really keep my eye on it as you mentioned.
          The mid pipe is made of aluminized metal and weighs nearly nothing.
          a pound max.
          The slip on weighs about seven pounds. The clamp is located about a third of the way up the pipe and supports all of the weight.

          I may just tack on a habger just to be safe.

            i would. the stock header is pretty heavy - and that 'can' clamp is to hold the 'can' up not support the header.
