The Remus Slip-On for the R Nine T is designed to work seamlessly with your stock bike, however for those seeking more airflow and a louder, more open exhaust note, Remus has released a flapper valve eliminator. This is a modified linkage pipe that will allow you to completely remove the butterfly/flapper valve on your R Nine T.
Note: Please check local laws before purchasing. Some modifications may be prohibited in some states.
Remus Butterfly Valve Eliminator BMW R Nine T 2014-2015
This is perfect fit and near perfect finish.
Just added some Permatex Copper Gasket Maker and it is perfect. Cleans up the entire left side and now no clunky box and makes the exhaust look much, much better.
All you need is a Torx wrench, electric tape, and nylon ties, as well as 10 minutes and you are good to go...
Much throatier at idle and it will pop and spit off throttle.
Add a KNN Filtercharger and the bike responds instantly to throttle input and the throttle is much, much smoother and linear.
It is well made out of single piece and fits perfectly.
Don't wait and get one...

Pricey but good fit and finish
Its a $50 piece of pipe someone more industrious could probably pick up off the floor of a muffler shop. That said, they did weld a strip of metal around the pipe which mirrors the BMW design on the flapper valve it replaces and once installed fits perfectly and looks like your bike came that way.

Direct fit to replace flapper valve
Fit perfectly in place of the original valve. Has a center rib on the outside to align the pipe evenly for the header and exhaust side. Just a little pricey, although it's well made.

Better than just a chunk of pipe
This is a great product for those who don't want a chunk of random pipe in place where the flapper-valve used to sit. This is well constructed and the only negative I can claim is that it doesn't come with sealant, so you'll likely have some carbon buildup outside unless you buy yourself a tube of exhaust sealer.
