Jeff -

Jardine make a quiet insert for their pipes; it might fit your model.

Once you add the QI you probably won't need to rejet ;^). You'll have an exhaust that is a bit louder than stock, flows about the same, and weighs less.

Jardine

Hey I also install a Jardine, the RT 99 and bought the so called quiet insert for it. To be honest I dont have any scientific way to measure it but by my ear I dont see where it does much silencing at all. To insert the quiet insert u have to take out the spark arrestor they wont work in tandem.
I took out the QI put the spark arerestor back in and cut the end of the QI off cut a slice down the middle of it and slid it in the stock endpipe for the muffler, and spot welded it. This gave me the quietest option for the muffler I could come up with.

Arrow jardine RT-4 exaust and jets

This is the jardine rt-4 exaust ...hopefully it will dampen the noise alittle, I'm supper happy with the new look, I dont think its the newist and greatest from jardine but I'm happy and feel I got a decent deal at $279?? (dont tell me if I dident)lol.
another one of my spuratic purchises was a dyno jet stage 1 & 2 kitt...I realize there is a lot of talk on this site around the JD jet kit...but Ive got this now is there any reason I should not install it or take it back in exchange for JD jets, )
Tom kindly mentioned I should try the 22 cent mod... but...I'm more into getting screwed for $60 or so, it comes with a needle is this similar to the klx needle ?

I think DJ/JD is six of one and a half dozen of another. Someone will probably send the bailiff to whack my peepee for saying that, but...

I haven't ever gotten my hands on a DJ needle to measure it for comparison to the KLX, so can't comment on its taper.

I installed the DJ stage one and drilled the slide, by the seat of the pants experience with exhaust and jet kit and K&N filter there is a vastly improved powerband form low to high end. Does it knock yur socks off no but how many 650 singles can do that. Was it worth the time and money for me yes. Oh yea and what good is money if not to enjoy a little of it.
