Single High Muffler

Recently I have seen several 919's for sale that have only one muffler high mounted in the stock position. Is there any performance advantage, other than weight savings, to removing the other muffler? I guess to do so, you have to remove the Y pipe after the header and connect a single pipe from the header collector up to the single muffler. Thats a little weight savings, but any performance gain?

Like the 900rr low mount header I don't think there are any performance gains or loses. The single sided high mount pipes usually come with a new mid pipe that replaces the Y-pipe.

I think some people like the look .... but am willing to bet the main advantage is cost, you only have to buy one muffler with the kit instead of running duals.

Two bros has a single high mount muffler system that can be mounted along with a matching dummy muffler that is used for storage. They provide you with a new mid pipe that replaces the y pipe.

I'm in the process of mounting a 2 Brother's 900RR header to a Katana 750 Ti Yosh Zyclone pipe. The Zyclone was a discontinued street baffle that makes even standard Yosh pipes seem loud. The Katana was the only one I could find in new condition, I've had a zyclone before and it's an excellent alternative for stock noise levels with less weight, stink etc..

I'll post pics when I'm done.

I've read the 900 header both does and doesn't decrease power. If mounting a light, low pipe you'd think the weight loss would make up the difference but does anyone know for sure? The diameter sure is thicker.

Cost would be a major consideration in addition to some weight loss.

In my opinion most folks would do a low mount 900RR header arrangement if there were simple (easy to install) options available. It's the most modern solution.
Again IMO, the next best solution is the single sided high mount - Two Bros version. And IMO it looks the best (LOL) and is nearly the lowest weight. It also sounds great. I'm probably biased because it's what I have.

A single canned 919 sounds like any other single canned inline 4.
Common, reedy, and not very inspiring, well, at least not to me, and thank goodness we all don't like all the same things!
A low mount 919 reusing stuff that can be applied to a 919, essentially translates to a single canned pipe BUT that setup does a good job of getting rid of the notorious 919 stink from the twin hi mounts.
I view the 919 exhaust stink as the worst aspect of the bike, and slow speed heavy traffic downwind travel on a hot summer day is awful for a passenger.

I had a Two Brothers high mount for a while. I liked it just fine. It was light. Some people liked the carbon fiber look. I thought it. Sounded ok.

Are you sure you aren't seeing 599's? They look very similar and the 599's have a single muffler stock

No, these have been actual 919's being advertised for sale on the various bike ad sources. My new to me 2007 still has the dual high mufflers, but the stock cans have been replaced with Erion racing mufflers.
