Does anyone know of a under tunnel exhaust for 2011-2015 Apex models. Would like to put one on a new 2015 Apex XTX. Not looking for anything to loud would like to use rear tunnel area for cargo space so exhaust would have to exit below.

I modified a stock exhaust by cutting of the outlets and remounting them facing forward under the Tunnel then build a checkerboard aluminium cover around the back end . This is a excellent quiet mod for trail use, not the silly loud under Tunnel exhausts.
If you are interested I will have a look if it is still around

Did you do this modification on a 2011 apex or newer. That would be cool if you could see if you still have it.
Thanks

Looks like I did trow it away , it was for a 2008 anyway.Did you do this modification on a 2011 apex or newer. That would be cool if you could see if you still have it.

It is easy to modify yours if you have a friend that is handy with a tig welder .
Just cut some holes facing forward beside the exhaust pipe that goes into the mufflerand weld a about 6 8 inch long tube facing forward under the tunnel on to them . Then cut of the exhaust outlets and weld a plate on them .
One important thing to do is to cut the Muffler open (make a lid on top) and partially gut it take out the silencer tubes that go to the original exaust outlet only. If you do not do this step yopu would loose flow and performance. even if you yake a cuting torch and cut big holes in them will do.
It is very quiet with that set up the only down side is that if you have the motor running and just sit on the sled you smell exhaust as it just comes out from right under the sled . kind of like a 2 stroke
