Why the Valvetronic Dump Pipe is Better Than an Exhaust on the Can-Am X3

There are many options to choose from when it comes to an exhaust for your Can-Am Maverick X3 Turbo.  Between price, style, and sound, most exhausts will do the same for your upgrade desires.  However when it comes to performance, there is a different way to look at things.  When you do an ECU tune, you set boost pressure parameters in the ECU code.  This is typically set to about 17psi instead of the stock 14psi in our VR Tuned ECU flash and as we have tested in others.  What the ECU says and what the car will do can differ.  Mechanically, you have variables such as the wastegate, blow off valves, and exhaust components.  If we focus on the exhaust system, you can see there is some major variance.  If 1psi of boost equals 10 horsepower in theory, than this graph and article will show you why the Agency Power valvetronic dump pipe is the best option for your Can-Am X3 Turbo!

Turbochargers do not need any back pressure or restriction.  The more air you get in and the more air you get out makes them extremely happy.  If you put a simple 3 inch pipe off the turbo exhaust side, it would be happy as hell.  However your ears would not be.  A turbo is one big air pump and if you put a blockage on the exit of the turbo, it will not perform how it should.  Want to see?  Grab a hairdryer and put your hand in front of the opening.  Hear it about to explode?  That back pressure is restricting the flow.  However, Can-Am is not building race cars for the masses, they are building vehicles designed for the general population that meet government regulations.  With this, restrictions and audible requirements must be met.

The Agency Power valvetronic race pipe features a valve that is switch operated from inside the cockpit.  When the valve is open, the exhaust gases from the turbo goes straight out the dump portion with no restriction or back pressure.  This gives a loud race sound that some truly prefer.  When it is closed, the exhaust gases go through the now catless pipe and into the stock or aftermarket muffler.  This keeps the exhaust tone tame and tolerable for most.  By not have a cat for race use, the restriction is eliminated, but not completely.  We plotted 3 different boost graphs to show you how the immediate atmosphere dump of the exhaust gases is better than the stock exhaust with a cat delete pipe or with an aftermarket exhaust.

  • Run #1 is a stock muffler with cat delete pipe that averages 15.4psi

  • Run #2 is an aftermarket muffler with cat delete pipe that averages 15.5psi

  • Run #3 is the Agency Power valvetronic dump pipe that averages 16.6psi
