2011 zx6r slip on getting extremely hot

Ok, this is a rather weird question and i cant seem to find any info about it.

so i bought a 2011 zx6r that runs great, the only thing is the slip on (a yoshimura) gets extremely hot. Now, Ive never had a kawasaki before until now, just cbrs, and the cbr slip ons never got this hot. if i let the bike idle long enough itll be extremely hot(10 minutes i think), where you cant
even touch it. is this normal? or is there some sort of issue ?

Most exhaust cans get very hot, aka why shrouds and such are needed for under-tail exhausts. I'd say as long as it is not touching anything that can melt, you're probably fine. Metal likes to get hot.

I tend to get things right on the secon... fourth attempt

Why are you idling it for 10 minutes?

exhaust systems get very hot, +400 degrees on the regular (and headers can easily get close to 1000*), they rely on airflow across them to keep them even relatively cool, it is very normal for the can to be above 160* right after a ride (and you aren't touching that without being burnt)

woohoo we are having fun now
Stupid people say stupid things on the internet, so be wary of who those people are. If you solicit advice on the internet, just keep in mind 99% of what you'll receive is not based on fact or science-and likely atleast 95% of it is based on bullshit and bravado regurgitated from some other schlub who also did not experience any of what they claim and are also full of shit. If you don't like my bluntness- too bad. I am not here to please you, so move along, your approval is not desired nor is it needed. So before opening your pie hole and adding more stupidity, perhaps sit back, listen, absorb and learn something. You know that saying, it is better to remain silent and thought a fool than to open your mouth and remove all doubt!

Yea, don't idle it for that long. Just sitting there idling, things are going to get hotter than they normally would if your were riding it.

So you're wondering why an exhaust pipe would be on the warm side?

I'm so confused.

3 reasons :

1: installed a pc5 to help fix the issue of bogging in the low rpms, which it did

2: its fucking cold outside, i cant really ride it around to test it.

and 3: fuel stabilizer

As i said above in the first post, All i had were cbrs in the the past(2003 and a 2008), and the slip ons NEVER got that hot. i was curious if this was normal.

How did you assess how warm the exhausts were on the CBRs, and then compare to the existing situation? IR thermal gun/camera? Accidentally touch them ? Just curious.

Just a thought: Yoshimura slipons need to be repacked over time; the packing material being a fiberglass material that insulates against heat and noise. If your pipe is fully packed with that material I could imagine maybe less heat making its way to the pipe’s outer surface? If it’s an older pipe with a damaged and/or depleted packing material, maybe it would get hotter? I’m just reaching here....

I’ve heard of people talking about lean fueling conditions contributing to elevated exhaust temps as well...

PS: I wouldn’t do that “hand touch” thing if I were you! When I am strapping my bike onto the trailer 20 minutes or so after coming off the race track I’ve burned my arm accidentally touching the stock exhaust....ouch!

well, the pc5 didnt contribute to it, as this issue was happening before that. im gonna see if the packing needs to be replaced, the guy cut down the slipon quite a bit, so he mightve ruined the insides

Get a silicon dong sleeve for your pipe.

Problem solved.
