Here's a video I found on Youtube of the 2017 Honda Rebel 300 with the exhaust (muffler) removed. Sounds so deep but I can only imagine how loud it really is in person.

Hey...that's my bike and video!! :grin2:

It's ear splittingly loud without a muffler. I barely tapped the throttle in the video because of how loud it was.
Are they viking bags you have on the back there? If so, did the supplied mounting hardware fit without the need for drilling?

They are the Viking bags. They supply all mounting pieces, though i had to go to the hardware for shorter mounting bolts.
They do require drilling, I think just about any aftermarket bags would.

Ah, getting my bike through PCP and not sure if I'm allowed to drill it?

Oh sweet! Sorry if you've already posted it on the forum, I wasn't too sure! But thanks for the content and I hope you don't mind me posting it :surprise:

I am having some trouble with my slip on. It seems like when I am accelerating in second gear the rear tire is almost stalling up. Not sure what would cause this but it isnt noticeable at higher speeds or higher gears, only when im in low gears.

Anybody know what would cause this?

Maybe the difference in back pressure is too much between stock and your Emgo?

That's why I went with the TBR... higher cost, but it was designed and built specifically for these bikes.

I mean it is essentially a straight pipe.... could it be bad for the bike to have too much backpressure?
Ryan,

It is very difficult too tune an engine to run without back pressure. With a carburetor it is virtually impossible to get an engine tuned correctly without having back pressure. With fuel injection I don't know as I have no experience changing the exhaust or intake on a fuel injected bike.
Someone more experienced will pipe in some info.

Yes, though in this case (being just a straight pipe), I'd say the issue is not enough back pressure.

As for doing actual damage to the bike? I'm not sure... but the performance hit alone would be enough for me to look into remedying the situation.

I have a slight hesitation in second gear w/ my Shorty slip on as well. It's only noticeable though if you're gunning it from stop light to stop light.
However it does go away within a few miles of riding, so not sure if the computer has to self adjust each time you're riding.

This is exactly what happens to me as well. It seems to only do it when the engine is "cold" and I am running wide open throttle *or at least this is the only time its very noticeable*. After I ride for maybe 3-5 minutes it doesn't seem to happen again. Apparently straight pipes give you higher top end performance diminish low end.

On a side note, but perhaps related note.... I was riding through the city the other day and pulled in my clutch and rev'd as I passed a group of ladies *they never should have let me have a bike*, and my bike stalled out. Very embarrassing to say the least lol....Not sure what happened but now I dont try to rev up and show off...wondering if it is the same issue.

Possibly, with the high RPMs and too low back pressure.
