FE-570 exhaust can - Page 3

I tried to take the end cap off the factory exhaust can of my 2011 FE 570, and found that it was silicon-glued in place at the factory. It won't budge. Ideas anyone?

That's how mine was so I stuck an old broom handle in the end cap and started gently pulling up and down and the seal broke loose. Then with a rubber mallet I smacked it back and forth from top to bottom and it came out. They are a very snug fit and it will take some patience. If you have a saws all you can cut the tube off in about 10 seconds, just squeeze it in a vise and let it rip.

Thanks, Bergman! (Now why didn't I think of a broomstick as an exhaust tool?) How much of the "tail pipe" do your recommend cutting off? I was thinking about cutting it at an angle so that the eliptical opening faces the primary tube. Good idea?

BTW, here's my solution to HSBS (Husaberg Scorched Boot Syndrome).

Good solution for a heat shield, I have carbon fiber now it works good too. I cut the tube off flush with the end cap leaving the welded brace in place. You probably won't notice any difference either way. You need to remove the sas device and misc smog lines next.

Wow! You cut off all of the tail pipe that you possibly could! What results did you realize? Is it much louder? Did you notice a difference in performance?

How'd you like to hold an on-line clinc? If you could provide some words and photos on the SAS device and the smog lines, it would really be beneficial!

Did any of you guys have to adjust your fueling? Like a different map or any tuning? Ive been wanting to open up my stock can but am worried about the fueling since it doesnt have an O2 sensor. At night my exhaust header has a slight red glow to it so that worried me even more and I dont wanna mess anything up.

I think it's probably safe to say that your exhaust can glows red in the dark because the hot gasses are held in it due to back pressure in the exhaust tract. I made a very minimal change to mine - I took 1/8th inch from the internal end of the tailpipe, and rounded the end inside and out to prmote gas flow. It made a difference. Throttle response is better, and it sounds more like a thumper and less like a sewing machine.

Ok thanks. Yea, I assumed it was glowing red either cuz it was lean (I live in California and emissions laws here are horrible to stock bikes) or because the stock exhaust is ridiclously restrictive. I guess its off to gut the muffler I go!

I took a conservative approach. I figured I could take a little off at a time, and incrementally ease into the solution. What I found is that the first increment was enough. In fact, I put the spark arrestor screen back in. But I've got a second screen on order, and I'm going to modify it to take off the inner layer of the screen. I think that's going to be the right combination for now.

Beyond that, the end piece (with all the holes in it), I have gone to some trouble to make sure it stays in. I want it to serve as a spark arrestor. I know it isn't certified, but from the design it looks like it would do the job. If it comes out then I will get an aftermarket tip that has a certified spark arrestor in it. There are a lot of neat forests around here and the last thing I want to be responsible for is burning them down.

Beyond that, on the trail, my bike has more than the needed power for my skill level, so I don't feel the need to replace the silencer at this point. If I get some SM wheels/tires I may get a different silencer for more power, but that isn't in my plans right now.

Not ure what is going on but I can see no picture. Can anybody else? Appreciate your concern a lot.
