Anyone change theirs yet? Much performance difference? Still only the slip ons available?

check out bikelands c14 site. they have a area p c14 full system that is impressive in a post there.

Yes, Muzzy makes a complete dual exhaust for the Concours14.

I does away with the cat converter and oxygen sensors if so equipped.

I run a Two Brothers Titanium slip on. GET ALL KINDS OF COMPLIMENTS.

Thats the one I've been looking at (Two Bros).

The Two Bros system was easy to install. They could not have made it easier.
It is SO much lighter and far more good lookin than that stock truck' muffler.
No spring involved..nice n clean. Really has a nice meaty sound. It was like getting a new bike again.
I considered the dual setup. But my ride has CA cat with two Oygen sensors. I didn't want to mess with that setup.
You will be blown away by the sound that comes out of that can when you get on the throttle..Wow! sounds like a Farrari.
Ride on...

AreaP makes both a slip on and a full system (w/O2 sensor bung). The AreaP, 2 Bros, and DiVince seem to be the most popular slip on being used. I have the AreaP with the flies out, PCV and BMC filter. This set up makes a significant difference in the bike. Much more linear and pulls strong from down low. Fuelmoto out of Wisconsin can provide everything you might need and can provide the PC premapped for the particular set up. The graph that they have for my set up show 150 hp at the wheel. Oh yeah, the AreaP looks and sounds almost identical to the Akro system that I have on my 12R. Sweet!
Definately dump the bazooka!

Remus Hexacone slip on and link pipe fitted to mine about half a house lighter than the standard exhaust also the note now a lot sweeter
