2014 VFR800 Exhaust Akrapovic Slip-On VS the Two Brothers S1R

So I have been doing a bit of research but I wanna get everyone else's opinion on this. I'm considering either the Akrapovic Slip-On Exhaust or the Two Brothers S1R Slip-On Exhaust for my 2014 VFR800. Which does everyone else prefer and why? I'm looking for mostly performance and then sound. From what I have seen it looks like the Two brothers is slightly better. So what does everyone else think and/or is there a 3rd option I should look into and may have missed.

 

I love my akrapovic. Not fussed by the sound but it only cost £150 and weighs a lot less than standard.

 

Might want to look/listen to Delkevic as well - several members here have one of their models and they are excellent bang for buck IMO. Here's a vid of mine (more on my yt channel). It really transforms the riding experience - I now feel like I've got the baddest bike on the street when I'm riding (even though clearly I don't - lol). It also shaved slightly over 7 lbs from the bike and according to the dyno on Delk's website adds 2.96 hp which is pretty nice.

+1 for Akrapovic ... sounds and goes better for it
