Unhappy Best Canister

Might as well choose the canister by the sound, as none will improve the performance or horsepower of your bike. The stock exhaust set up provides the best performance and horsepower. The stock exhaust sure doesn't sound good, but it provides the best engine output.

Patman's KLR 650 Dyno Results



Better to spend the money on a 685 kit than a pipe if you're after actual horspower gains.

Not to mention... Loud pipes lose rights

How about a 3hp gain with a White Brothers. Not every exhaust is going to make more HP but to say that no aftermarket exhaust will make as much HP as the stock exhaust is silly. For the average price of $260 bucks that is a decent performance return.
The Big Gun Patman used provided some low end torque but didn't produced significant HP until they modified the box core which yielded an additional 5 HP on his 685.

Pulling the spark arrestor from the White Brothers yielded an additional 2ft lbs torque from 3300rpm to 5200rpm for a total gain of 5ft lbs over stock. That's a substansial gain for a motor that only makes 32ft lbs.

I dont know if the Staintune brand is available in the US and call me biased but you cant go past the slipon exhaust box from Staintune made here in Australia.
I have one fitted to my 2010KLR and the bike has noticable power increase, substantially louder but still legal, fits in 5 minutes with no modifications, never needs repacking, wont melt your plastic sidecover, fantastic build quality and I think it looks great.
I do sound biased but its only because I am so happy with the pipe.
Probably the best bolt on modification to do to the KLR.

Forgot to mention it is a lot lighter than the stock pipe, physically smaller and a 130 rear tyre wont scrape. WOW!

It's still a KLR... 20+ year old tech with a relatively slow revving motor. So you've managed to get a bit more out of it, big whoop! The extra noise (vs. the slight power gains) the pipe is going to generate is not worth the ill will it's going to create.

To the OP have you done the .22 mod? That will wake up the throttle response more than changing the silencer. If you have to make the bike louder look into the low buck exhaust mod.

That exhaust just happened to register only 1 to 2 decibels higher than the stock exhaust.

Besides which, this debate was whether an aftermarket exhaust would produce more power or not, not whether it produced more sound. I can accept a decibel or 2 increase to get a 10% HP and 15% torque gain. Obviously your opinion may very.
