Hi, I have just bought a 2005 KLR650 and would like to know more about aftermarket exhausts. There seems to be a lot of controversy on the topic with a lot of heresay. Is there anyone out there that has actually done it and had either positive or negative results? I would be really greatful to hear from you. Cheers Sean

There is no controversy. There has been at least a half dozen listers who have done it. None of them report positive results, other than a better sound (as vs. the normal lawnmower noise). -E

Hi Sean, I have tried the Big Guns and the Laser ProDuros. I have gone through 3 Big Guns*, they are just not the right exhaust for this machine. If you only put 1000 miles on your bike a year, or you have a pure race bike then they are fine, I guess. I have had 3 of them fall apart on me, and they instantly need repacking. A good weekend is 600-1000 miles on my KLR, and the packing blows out after that. Not to mention the riveting and button head bolts stripping out and the ends of the can falling apart. They are also louder than hell. Really miserably loud. People will hate you, and after a couple of hundred miles, you will hate yourself. Look elsewhere. * I bought one, it blew up, they replaced it, that one went bye bye, then I won one at an auction at an AMA ride and got it dirt cheap. It blew the "quiet core vortex insert" out of it's butt after less than 200 miles (it melted and completely toasted the head pipe, too), they replaced that, and now a brand new Big Gun exhaust pipe sits on my shop bench. The Lasers have been good. Zero maintenance, and the Quiet seires is even quieter than the stock exhaust. The Off Road seies is substantially louder than stock, and I have managed to knock the insides of that one loose. It rattles inside the can. Why? I don't know. The only other one I can honestly say I've seen get any kind of usage is the old style (external disc) Supertrapp, and it seems pretty sturdy. I suggest sticking with a stock pipe, myself. If you absolutely have to go aftermarket, look at the Laser. I would like to check out the FMF pipe, they are a good company as far as I know, but I have no personal experience withe their KLR pipe, so I can't honestly recommend it one way or the other. Thanks CA Stu A13 A14

Hi all, Ok I have to chime in on this one. Everyone here is correct. There is NO gains to be made by putting and aftermarket muffler on the KLR. Been there and done it. But on the other hand, the stock pipe starts out sounding whimpy but quiet , the quiet is a good thing. Then it sounds like a VW Beetle that I just could not stand anymore. So..... out came my tubing bender, tig welder and some aluminum. I made a Supertrapp type exhaust with the trapp end cap with the USFS stamp. Made the can a bit different so it will be quieter, no gain in power, but it sure as h_ll sounded much better. Rode for a while and decided to start tinkering again. So I made a new header with a larger initial bend and stepped it gradually to a 2 1/4 in by the time it got to the subframe. That made a difference, not the muffler. In my opinion, the head has bad flow, but the header pipe is even worse. FWIW, Adam 04 KLR650 04 KTM450MXC (stock pipe, much better unit than Kawa will ever have) --- In DSN_KLR650@yahoogroups.com, "sean_england7" wrote:

How can you possibly assert that a simply change in header pipe size and radius will make a difference? Obviously you have no engineering expertise or you would immediately recognize that solutions are never this simple. Check any engineered system and you will see what I mean. (VBG) Wow! Is this worth exploring! Great suggestion and some solid insight. I love solutions which are simple and this is just another example. Can you provide more details such as quantitative or even qualitative indicators of more power? Did you try some third gear roll ons against another bike to serve as a control? Or maybe steady speed run up a hill? Was any jetting change required or have you explored that as yet? The stock header is about 1.69" OD with quite a tight bend as you point out. Have you any pictures? Norm

What's with #157156, 157157, 157158, 157160 and 157161 ? Sticky button on the keyboard? Thought my computer was locked up (again) until I noticed the numbers were changing. Bruce
