Two brothers exhaust

I am putting a slip-on exhaust on my 2010 klr, and I found that the s-pipe is very close to the inner fender then I wonder if that is the way it is suppose be.
In the hardware that came with it there is a bolt and a black plastic spacer, the bolt is to short if I use the spacer, it looks like the s-pipe will get a little away from the inner fender if I use the spacer, but maybe to close to the side panel.
The instruction shows a 2007 klr where exhaust mount is a little different, so I don't really know what parts to use.

It should look about like this. This is not a Two Brothers installation, but similar.


I figure there should be an air gap of half an inch or more between the muffler and the side panel. The side panel has heat resistant stuff on the inside to protect it.

That said, I would err on the side of caution and would much rather that the mid-pipe melt the inner fender than the side panel.

Nobody cares about the inner fender, but a melted side panel is ugly.

No, you may not ask me how I know that...

It's also a good idea to disconnect the dog bones from the toggle link so that you can fully raise the suspension to make sure that the tire does not hit the mid-pipe and the brake bleeder valve doesn't hit the muffler.

And, no, you can't ask how I know that, either...

Any mod which increases the flow through the engine will lean the mixture. The KLR is plenty lean to meet emissions. This is why people see things like poor throttle response, white sparkplugs, backfiring, surging at steady throttle while cruising on the highway. The 22cent mod or the klx needle mod cures these issues but at the cost of a small loss of fuel milage. Remember....Heavy load + lean mixtures =heat and bad things can happen!
