That's awesome.

I was feeling pretty "meh" about the current offerings until I saw that. The big advantage I see over the others is the weight savings, much shorter and much lighter, which is precisely why I wanted to remove my stock exhaust in the first place, well that and the noise to make sure I don't sneak up on someone's blindspot.

Got any weight and length specs versus the stock exhaust? How about an installed video showing the sound?

Oooh That cleans up the rear of the bike quite nicely.
Very nice indeed. If it isn't terribly loud, I might have to reconsider my decision to not upgrade my exhaust.

That's pretty sweet looking. I wish I could find a sound clip.

ill ask m4 tomorrow to see if they made a video of them yet / dyno tune / weight savings..

it does come with a removable db killer sound reducer... so if its not loud enough you can take that out..

the shorty only comes in carbon
i have the standard mount ones in polished stainless/ carbon and titanium..
im getting those listed on the site now.

Considering I was just going to pull my exhaust and install a megaphone, this will be much more quiet. I don't think I would use the silencer personally.

I may still do the megaphone for a few months then when there are some long term reviews on this one, switch over and pull out my earplugs. Or wait for a full system to come out.

That's all good info, loud pipes saves lives. Well my bike is black so a carbon pipe is alright with me, kinda asking for all the other people out there. Nice to see the parts coming out lil by little for my deuce50

I'm interested in this too. If it's got a good sound, I'll probably get it over the yosh. Please post sound clips (with and without db killers).

I'm also interested in torque and hp curves. Info?

I must be getting old or something, cause imo they look like crap. Even the shorties on the big blade look **** if u ask me, but each to their own, and the more stuff on the market hopefully the competition makes everything cheaper and better. 2Bros carbon slip-on installed on mine(full size just the way I like it)
