Aftermarket header on stock can vs. Aftermarket can

[Ashslider33]

What's up from Texas,
I have akro headers to the stock can and it is LOUD! A little too loud for long touring trips, does anyone know if getting an aftermarket end can will make it quieter at all? Or even maybe just help with the droning around 80mph? Any help or experience with this would be appreciated.

Thanks

From what I have read on this site, the OE can is straight through and the noise reduction was sorted with the cat, so any aftermarket can that comes with a baffle should be quieter. 

Pretty sure someone will be along soon to confirm or debunk my thoughts..

Perhaps get an Akra slip-on but with removable db killer ?

I have the full Akra set for my Gen 2, but haven’t fitted the headers yet, just the slip-on in combination with disabled (open) exhaust flap. This set-up gave me much more sound, even some pops and bangs on deccel, but not too loud. To be honest, it sounds so nice that it made me question should I fit the headers at all…

I can confirm that putting a db killer on a muffler with unrestricted headers does improve noise levels. I run S1000RR headers with Arrow slipon (with db killer) and I find noise levels quite tolerable. I did remove the db killer for a trip and noise was obnoxius especially when we were traveling in b roads and I was running the bike in lower/mid range rpms.

I run full headers stock can, for me personally, riding with earplugs all the time, it's never "annoying" but sometimes I wouldn't mind a bit more peace and quiet, that said I don't think the headers increase overall volume that much since a large portion of the sound comes from the airbox and even more from wind noise, when I fitted the headers, being on the bike, cruising it's barely louder than stock, except for the pops, off the bike though, in 3rd person? Whole different story, my first reaction to recording someone riding my bike, so i can hear what it sounds like from the outside was "Holy sh*t i feel bad for the people I drive past in towns" . Something like a longer Mivv can with a DB killer might help, I know a guy that runs that setup and whilst at the time I didn't have my headers yet, it didn't seem drastically louder than stock. I'm just really unsure about DB killers after seeing a lot of videos on various bikes where even big brand exhausts lose 5+ bhp from a DB killer alone. And I know 5 bhp from 160 is still a lot, but you know how it is :P

Apart from a test run around the block if I’ve been working on a bike can’t remember the last time I travelled any distance one up, always have my other half on the back,  if the combo of Akra headers MiVV end can was remotely noisy which has been on the bike for some years i’d Soon be informed.....

I have Black Widow headers and end can, I have the baffle in but found it dulled it a bit too much for my liking so drilled holes in it until I was happy with the sound, just another option

Thanks everyone for the suggestions, I didn't realize the stock end can was pretty much just a straight threw pipe. I guess I will be looking for an aftermarket end can in the near future when my finances allow me too. Really like what the akro. and arrow sound like.

I have full Akra system with no dB killer on my '16, it's loud and it drones.  Had an '18 with stock system MUCH quieter.
