Those excact slip ons aren't for S4RS - other than that I don't know much about them.
The only ones I've heard of that doesn't require ANY fuel adjustments are the Quat Exbox.
That being said, most slip ons work fine as long as you don't replace the udder with a midpipe and open up the air box.

There are many opinions and possibilities on this subject. Mine is only one.
Nevertheless, it's a fact that our bikes sound much better with aftermarket exhaust.

If you like the appearance of the stock mufflers (I do), then I have a pair of stock S4R mufflers in excellent condition that I spent a weekend carefully coring for more sound.  The process I followed took more effort, but maintainted the stock length and appearance.  When I went to install them on my S2R1000, I learned the two bikes have different diameter pipes, so there went all my hard work.  I later followed the same procedure on my stock S2R1000 mufflers and am happy with the result.  

I have been meaning to post a "for sale" ad for the pair of mufflers that do not fit my bike.  Let me know if you are interested.  I can send digital photos.  I am asking $250.

i thought the s4r and s2r have the same size cans.

its the S4Rs and T that have the larger ones...

From what I've gathered, the S2R800s and S4Rs share the larger diameter pipe.  The S2R1000 is unique.
