Considering selling my Leo Vance slip-ons for a set of carbons, but want your guys' opinion on the loudest deepest set on the market.

I only have slip-ons but you can refer me to full sets, I would just need to get a PC first I assume.

Another vote for the Toce system. We have a lot of bikes roll up all year with work - in 5 years an R1 with Toce slashcut was the loudest in all that time.

Audible on tickover from several hundred metres.

Shame its not a nice sound, it grates.

I'd say Graves low mount, it's what I have and you can hear me coming a mile or so away and has an amazing sound/power around 4k and up in the RPM's. Plus you drop a ton of weight with it as well. IMO I don't care for the under tail exhaust look too much, plus after a while you booty feels like it's on fire after some time. If you are looking for a good deep sounding slip on I'd take a look at the Hotbodies Racing MGP, the cans are short and don't go past the tail light like most on the market, plus it has a clean look for an under tail exhaust and sounds amazing as well.

Add another for the Graves Low Mount. Currently running that on my 09, but already have a Leo Vince full system I'm gonna be swapping it out with.

Racefit Growlers would be loud, but like the low mounts, it's an acquired taste.

Another vote for the Graves low mount. It is a full system, and even the stainless version drops a true 15 pounds of weight over the OEM system (which of course even has Ti headers and can sleeves). I did a lot of research as I just recently bought my first R1 - a Crossplane.

If you needed more convincing, watch YouTube user "rnickeymouse" videos of Mulholland Drive in SoCal - like this one in particular - lots of R1s:

I love the graves sound. One other that I have heard is RLS exhaust. Very affordable and sounds so mean. Very loud tho. Some people may not like how loud. But I love it. Will be getting one for my 09 and if I end up not liking it I won't be mad bc of the price!! They have a few different models to choose from. They have a prototype for the 09+ and I think it looks best. The prototype can be seen on their Facebook
