Which after market muffler?

I only just purchased my second KLR this week. I bought a 2007 and passed my 1997 onto my son. The problem is my sons motorcylce will run circles around mine and on a recent trip I got 48 MPG to his 53. He has a super trapp muffler and I suspect his carb has been rejetted.

My local motorcycle shop has strongly suggested a vance hines XCR over a super trapp muffler and a stage 1 rejet over a stage 2. My goal it to increase power and at the very least maintain current gas mileage. From reading the forums here I think folks on here have better info to go on than my local Kawasaki dealership.

Any suggestions on after market muffler and rejet would be appreciated.

I bought a vance hines muffler and stage one jet kit. The bike runs great but pops once in a while when I accelerate. I have noticed its much more responsive in lower gears but seems to have lost some on the top end. What can I do to improve the top end? I have looked into the 385 upgrade but its costs prohibitive at this point. I drive on the highway alot and would like to use at 16 tooth sprocket

DO NOT, under any circumstances, use a Jardine RT-5 and stage 2 Dynajet kit...

It's incredibly loud - even wth the quite module insert (QMI). It's meant to be just shy of 100Db, however they must have measured the sound level before opening the throttle. Get good ear plugs.

This, combined with the stage 2 kit seriously wakes the KLR up in the low-mid range.

It's nice to have KTMs and Ducatis make way when they feel you bearing down on them.

Hey Karl,

Did you go with the stage 2 because you opened the air box up? I had an White Brothers E2 on my 07 KLR and did the stage one and a K & N. The bike was very loud. and had lots of mid power.

Hi,

I went with the Dynojet stage 2 carb settings (142 Jet/ needle 2nd step w/2 washers), a Unifilter and instead of sawing out a big "L" in the airbox I'm using some of these in a rough "L" pattern. Mixture screw backed out 2.5 turns.

Great Low and Mid but a bit of a narrow flatspot at around 95km/hr (~55mph). Still quite an improvement over stock config.

Thanks Karl,

Did your muffler come with the quiet module and if so did you install it? After the install did you feel any reduction in felt vibration?
