That's my old building but not my bike, mine is older and all black (no stickers).
How many of you guys still run your stock exhaust? I like the fact it's quite, but it's got to be restricting it quite abit you'd think. Any recommendations on aftermarket pipes? I'm thinking the Super Trapp IDS2 maybe.
I had an aftermarket exhaust on my '97 KLR and it was quite loud. So with my '10 I'm trying to stick with the stock exhaust. There are times when I want to mod it, but there are also times I'm happy I can cruise around quietly without making a huge racket.
I run the stock exhaust on both my bikes. Used to run the Super Trapp on my 88 and took it off, what a PIA is was to repack. ... all the bolts broke off!!!
I have a IDS2 on my bike. I don't know if the problems I have with it are common or not, and I don't know if the previous owner contributed to it or not, but I plan on replacing it. There are 3 holes in the end of the muffler, under the cap, that allow you to insert the tuning discs and spark cap. The PO had none of these installed. I installed them and discovered that one of the holes was stripped. I ran the bike with a few discs and the cap for about 80 miles, and it blew out both of the screws in that time. I MIGHT be able to have something welded/rigged to hold the discs and cap, but not sure how long it would last.
To be fair, there are a few mystery holes drilled in the bottom of the muffler as well, so I think someone did something weird at some point in time. I'm planning to eventually order a Lexx to replace it.
I'm still runnin' the stock exhaust for a few reasons...
1. I have owned a buttload of motorcycles in my lifetime (and I'm not even that old...I think.) In retrospect (and for the most part), the bikes I have enjoyed the most, and that have been the most reliable, are the ones I haven't turned-into Frankenstein bikes. On top of that, I am a person who will be late to his own funeral. So, everyday, I'm rushing to get to work. It is quite nice when I run-out to the garage, thumb the starter, and haul ass...no muss, no fuss.
2. From my research, it appears that there is not a whole lot to be gained by just a pipe and jetting. It seems that the $0.22 mod is nice for folks wanting a little more, and that a 685 is the way to go if you really want to see some gains. For me, I've done nothing but drill the stopper on the screw (which helped with the hard starting). YMMV...
3. Even though I'm not that old, I like the silence. I can haul-ass by a cop who is screwing with his MDT, at wide-open throttle, and he doesn't even know I'm there. And, if he does happen to look-up, the guy with the leaf blower is putting-out more noise (and horsepower) than me, anyway.
Good luck with your search. If you find something that really works, please share. Cheers.
I ordered the Lexx this past weekend but from what i've read it doesn't seem too bad. I had an old beat do death unpacked Cobra on mine when I bought it and it was obnoxious. When I put the stock muffler back it was choked down due to being jetted for the gutted muffler. We'll see how the Lexx works for my needs.
Loud Sucks. In our group if you have a loud pipe, you ride in back the of the pack.
Supertrapp is probably the worst piece of shit you could waste your money on. Poorly built, noisy, and tend to fall apart. (I had one that ended up being recycled.) Mid pipe is not stainless, so it tends to rust. Really don't waste your money on one!
I like the Leo Vince, you can have it noisy or you can have it as quiet as stock. Quality is VG. And it looks very nice. Has stainless steel packing, too, I believe so it won't need to be repacked. The only other one on the market that features that is Staintune--it's more expensive than gold, so we mere mortals can't possibly afford it.
I have a White Bros XCR, it's now made and marketed by Vance & Hines. I got mine for about half the new price (and it was practically new at the time.) The p-o didn't like the louder sound (approx 94 db rather than stock ~84 db.) You can get one for $256 or so shipped--do a search, but OEMcycle comes to mind for some reason. I would rate the quality as very good--stainless steel mid pipe, fits the stock header without clamps. The noise is louder than stock, but not bad for me (and I'm a bit of an old faht!)
Stock--heavy, quiet, not as restrictive as you might think. Lots of fellers on that (not to be named but they do a lot of censorship) other big motorcycle forum that specializes in KLR, do a low buck exhaust conversion. You cut out the end of the pipe, remove a bit of the baffling and put an aftermarket tip on the stock muffler. Uncorks the sound a little, gets rid of the tweety. Best, you can do the whole shootin match for less than $40.
I think the aftermarket pipe does uncork the engine a bit. But my sanity is questionable as (hence the username) I've done a Schnitz Racing 685 overbore (and a few other performance oriented bs things.) All combine to give me a smoother bike, and more power thru out the power range.
sorry, wrong thread
Its not as restrictive as you'd think. I still run one on mine. Nice part with stock is its a baffle design thus no repacking. Only 2 aftermarket mufflers available that are the same design....Staintune and LeoVince. I've thrown more Super Trapp's in the garbage than I care to remember.
Install a KLX needle kit, pull the snorkle, adjust the fuel screw, rejet main to smaller (I know, I know - its true) and if you want a bit quicker throttle response drill slide to 7/64th. In the end you have a bike that responds much better than stock but if you are looking for seat of the pants HP gains look for another bike. The KLR is still an overweight, undersuspended and little HP DS thats fun to ride.
Some of us have had DR's (some of us need doctors!) But you may not have noticed the thread heading? Questions about DR's are gonna probably be best asked in the DR threads?
.. ah well .. someone forgot to read the heading on the KLR 650 Only thread .. alas, this is NOT a DR650 thread .. JIC (just in case) you didn't notice .. unless someone is using DR650 parts on their KLR .. somehow I missed that trick/mod ..
.. as for KLR650 Stock Pipe ..
Still got mine and don't plan on replacing it anytime soon .. unless it's with another stock pipe .. if not, then I'll shell out the dollars for a Staintune ..
.. other reasons to stay stock ..
The stocker sounds like an old VW Bug, and I like that since a KLR handles like an old VW Bug ..
While everyone else is getting rid of tweety, mine (now) sounds unique ..
Since I don't ride like an off-road pro I feel no need to sound like one ..
Park Service Rangers don't even bother to check .. they can tell by the sound that it's legal ..
I like quiet these days .. I got the poor hearing from years of loud pipes and other loud noises .. mild tuning and you don't need to change it anyway .. and did I mention quiet?? I can understand performance enhances .. so some like it loud(er) .. go for it .. just not my cup 'o tea .. though I am thinking about trying that power-bomb header to see if it really does help make the bike even quieter ..
I don't kid myself (anymore) into thinking loud pipes save lives .. after years of running skirt blowers on my cruiser the only people that ever heard it were the pedestrians .. cars are made to well these days, and with the radio on most people can't even hear fire trucks ..
I personally don't like the stock muffler, I feel it ruins the whole look of the bike. It makes it look older and outdated, so it will be replaced, even if it does make the bike a bit louder. I'm not expecting HP gains, at least not big ones with just a pipe...
Supertrapps suck. Do the frugal mod.
.. no .. that's just me .. :huh
.. though it is about butt ugly ..
.. oh wait .. that's me too ..
.. dangit ..
Wonder why Trapps suck now. In the older days they were about as good as you could possibly get, especially if you were looking for tuneability. Unless the non-tuneable ones are the ones that suck.
The IDS (Internal Disc Series) Supertrapp had a reputation for falling apart when people tried to repack them, but as far as the old style external discs, I'm not aware of them having a bad rap at all.
They are light and simple, and if you run a small number of discs they are pretty quiet.
I had a Supertrapp on my Transalp. It was a nice pipe. All stainless steel, the threaded nut thingies that the screws for the disks screwed into were sturdy and didn't strip. No rusting mid pipe, and it was all stainless. Mine was well packed and over about 10k mi it never needed repacking. That was a design from about 1988.
The IDS2 I had was the straight thru "racing" model. I got it used, needed to put an endcap and disk (spacers) on it--and repacked it at the same time.
What makes it shitty:
The body of the muffler is aluminum--prone to denting, getting misshaped, and is difficult to repack. Also never looks good.
The fasteners that hold the endcap and disks on tend to strip as do the fasteners that hold the front of the muffler to the actual muffler tube.
The mid pipe is mid steel that comes painted with black (barbeque) paint. Under the paint, the pipe rusts--so that it looks like shit. Kinda like Gen 1 KLR header pipe.
The pipe is loud. If you use few enough disks to keep it quiet, it's restrictive. If you open it up to try to get some gas flow, it's a loud sumbitch.
Sorry, Supertrapp, but this is an old, tired design that never was any good.
If you get one of the competition, my XCR for example, you get a quality system approach to an exhaust can. It's USFS certified. The fasteners don't strip, the body of the muffler looks well built and polished. And it comes with a stainless mid-pipe that starts out shiny-chromie and heats in to a golden color that perfectly matches the golden brown of the stock Gen2 exhaust header. Mine has about 7000 miles on it and still doesn't appear to need a repack. And it's quiet enough that my neighbors (mostly blue hairs) haven't complained.
I've said that one of the pipes I'm really impressed with is the Leo Vince. Well built, quiet, & legal in the forests. Nice competitive price, and it's got stainless steel packing. If I were buying another pipe, it would be Leo Vince.
If all you can afford is Supertrapp, save a little longer and get something else.
