Default Kerker Experience

So, I did a search and found some 200+ threads with the word "Kerker" in them.

I spent some time digging though the posts. Some, I never saw the word "Kerker" (why does the search engine dump those to me if I can't click on the post the search term was in?) and others didn't seem to be the "Kerker" I am looking for info on. I'm not saying it isn't in there; just, I didn't read all of those threads that closely.

Anyway, now that I've dispensed with the formalities....

I am interested in making the Kerker pipe below fit on my 2009 XR1200:

http://www.jcmotors.com/p-9936-kerke...ter-86-03.aspx



This pipe was made for the 1986-2003 Sportsters (non-rubber mount and non-O2 sensors). It looks like all all I need to do is install O2 Sensor Bungs and rig up some way to hang the exhaust off the back.

Has anyone ever owned this particular style of Kerker? I'd really like to get some info from them ...and maybe even BUY that old Kerker from you, if you aren't using it anymore!

I have read these were MONSTERS when it came to power, and that is why Supertrapp bought them out.

Here's my "Concept Pic" of it installed on my XR1200:

Below are some pictures of the installed Kerker exhaust on my 03 sportster, keep in mind I did shorten the muffler 5 inches. As far as installation on a later model, I think you will be ok, the pipes should fit the motor fine although you will have to install O2 bungs, but the rubber mounted frame is different so the support arm that comes with this probably won't work. That being said if you have fabrication skills I am sure you can make a different support or bracket to run this exhaust. It sounds great and definitely flows well, and still has great ground and lean clearance.

That ring that holds the muffler up: I assume it slides around?

I'd likely need to flip it so that I can position the mount at the top.

Otherwise, it looks like "ADD O2 SENSORS" and I'd be done!

Yes the strap can be moved or rotated. From your mock up photo you may be able to make a mounting plate from your upper shock mount, that;'s the best I can tell as this model has different frame design than the standard sportys.

So far, this is all sounding good to me.

If you get a chance, could you measure the pipe diameters? The headers should be 1-3/4 inch, but what size is the collector? 2-inch? And, what size is the hole coming out the back? Also 2-inch or 2.5-inch?

I appreciate all the help, too!
