The Lexx with the quiet core (gov't approved) spark arrestor is the most popular
replacement on this site. Under two hundred bucks, high quality finish and fitment,
and just barely louder than stock with high flow.
Two of us went weird with a GSXR 750 muffler (bright silver) , and I used a Honda 400
megaphone styled long muffler (now black).
If it fits use it. If it doesn't, make it fit. LOL

Addition: (see below)
At your elevation the jetting is probably spot-on perfect.
Maybe the needle (.22) mod for midrange which is what
I wanted to say to
about the jetting and/ or KLX needle or .22 mod and backing
out the idle screw 1/3 to 1/2 turn from where it's at.
(There's threads on that mixture balancing mod.)
"Care and feeding of the CV carb", click search, or find
the sticky somewhere at the top of the page.
The question: which was Lexx,
I believe that the Quiet core baffle and screen provide enough
backpressure to not require a rejet. The issue at hand is the
factory settings for idle and cruise (the two places the EPA tests
emissions) are lean to begin with, hence the needle and screw
adjustment/ modifications. This is going to be more of an issue
with any aftermarket or cored-stock blast can.
A full stage one will probably require a thicker mix thru the range
with the higher breathing if the standard intake mods are in place.
