The vibration thing concerns me. I know it would drive me completely nuts.
I've been working on similar issue and experimenting with some thick rubber washers from the hardware store. I placed one on either side of the hanger with a similar sized fender washer and used a slightly longer bolt Seems to reduce things a fair amount, but I didnt really have issues with the way it was either.
I have yet to hear the Delkevic exhaust in person, however every exhaust I have heard on the F800GS I did not like, save for the Akrapovic.
I had my bike out over the weekend and I must admit I really like the stock exhaust note.
I’ve mounted the stainless tri oval and found that with the baffle inserted it’s probably a bit corked up and ran a bit flat on top. Very quiet with just a slight low rpm increase in sound(quality).
With the insert removed it was super annoying around town and at low rpm but surprisingly quiet at speed. I noticed and increase in top end (slight) and a decrease in low end (slight). I the made a 3/4 hole in the end of the baffle which has given it the sound I was looking for. Very nice low tone at idle with a progressive increase at higher rpm. I have to put a decent ride on it to allow for the ecu to adjust to give a fair assessment of the impact on power delivery.
It about a 1/4 of the weight of the stock can. I haven’t noticed any new vibrations but in my experience it will fatigue without additional isolation mounting. Once I have the sound/power to my liking I’ll probably get a second can mount and run two with a shared mount via an isolator bushing. I’ll report back once that’s done.
I'm looking forward to what you come up with ;-)
@rwcfrank01 Great info! What length was your tri-oval?
320mm SS tri oval
I referred to the 18”.
The 14” without baffle is louder, also tone is less low.
Volume of Akrapovic without baffles sits between those two I’d say.
I just recently put the 18” back on after cutting 2.5” off the link pipe, made it visually more pleasing how it fits on the bike, maybe I should have done that long ago.
About the simpler connection commented on, I have the worst vibrations with the rubber mounted, spring connected stock exhaust.
Both the Delkevic and Akrapovic with the clamps to header and solid or rubber linked frame connection points have less annoying vibrations throughout the RPM range (regardless of baffle in or out)
I agree with shortening the link pipe, you’re right it’s longer than it needs to be! Good call.
@morfic - I have the 18" Delkevic, with solid clamp to frame.
Any chance I could talk you into posting a picture of the rubber linked frame connection?
All of the danmoto ones are $60-90 right now, yay being a cheap bastard
Anybody have one of these Danmoto cans installed now? Love some feedback on longevity, sound, sound level(loud?), fitment, spark arrestor, etc.
I’m running a Jisu. Good quality and sounds nice but it’s pretty damn loud. I’m likely going to add a db killer to quiet it down a bit.
Ordered a Danmoto exhaust for my F650GS twin. Smoking prices right now.
Added the db killer baffle to the order because my instincts tell me it'll be too loud for me without it
Good call. I have a JISU and with the baffle in it's perfect.
Mines been installed since July 2018 and zero issues so far. It's a little sun faded but other than that it's held up well, no rust, no rivets backing out at all.
There isn't a spark arrestor, but here is a shot of the baffle
and the JISU sans baffle, straight through hah
Thanks, that is excellent info, much appreciated.
How loud was it without the baffle?
I have a feeling it'll be too loud, at least for me, if the pipe I got is straight through like your pipe is...
I'm glad I ordered the baffle straight away with the pipe...
I'd get the insert as well, the video sounds pretty 'throaty' without and I really don't want to be too obnoxiously loud.
Hmm.. how to put this in non-scientific internet terms..
Without the baffle I'd say it was below illegal loud but above asshole loud. Maybe late 90's ricer Civic loud, but not quite 2010's Subaru vape-boi loud. It sounded fierce but I felt like a dick driving through neighborhoods in the morning on my commute haha.
Edit: here is a terrible phone video from when I first put it on before I got the baffle.
That didn't seem too loud....what did you tach it up to in that video? Seems like it won't make my ears bleed as long as I don'r rev it up over 5k...
