Kawasaki did a great job with the KLR. My bike has covered over 52,000 miles. I've personalized it with a few changes. The following pictures highlight what I've done. I apologize for the dirt in some of the pictures; its a dual-sport bike - its ok to spend more time riding than washing.

LASER PRO DURO EXHAUST. At this point I haven't done anything to the Airbox other than put a Twin-Air re-useable filter in it. I'm still running the stock jetting. Jetting is on my list of things to play with. I'm not a close MPG watcher, but I think I picked up a couple MPG with the Laser. The biggest riding difference has been smoothing out the on throttle to abrupt off throttle transition.
The Laser Pro really is as quiet as stock. Some people think it sounds a little deeper. Unless you really twist the grip, I don't think its really even any deeper sounding than the stock exhaust with 20K on it that I took off. I found it to be an easier install than all the exhaust reducer/bushing stuff mentioned on the Arrowhead Motorsports site. I shimmed one of the collector pipe clamps with some neatly trimmed and folded aluminum beer can to make sure it was tight enough. I did use a longer rear hanger bolt, it makes the installation easier with only one set of hands, but wasn't an absolute requirement. The only negative I've noticed is when I bottom out the rear suspension, the tire will rub the Laser collector pipe. They barely contact and it hasn't caused any problems. I positioned the pipes and muffler to be as far away from the plastic as possible. Perhaps in doing so I've gotten a little further into the rear tire's path than I need to be.LASER PRO DURO Update: AT 46,000 miles I broke the weld between the collector pipe and the muffler. I was on a particularly long and rough section of "road" in Baja and the weld broke all the way around. I discovered the hanger had broken also. I theorize that the hanger may have broken first so the muffler was hanging unsupported. Furthermore the weight of my fully loaded soft saddlebag rests against the muffler. Every bump would put additional side force on the muffler. Under full suspension compression I had contact between the rear tire and the collector pipe. Some combination of all these events snapped it. I found a muffler shop in Guerrero Negro that did a great job welding it all back together for 100 pesos. I was ordering a new chain and sprocket from Fred at Arrowhead Motorsports and mentioned the muffler event to him. He said it was the first one he had ever heard of that failed. Even though it is long out of warranty, he indicated Laser Pro Duro has some great customer service policies and would likely replace it at cost.
I've received quite few emails requesting p/n information on the LP TURN SIGNALS.
