• 3″ cat back system in brushed 304 stainless steel
• Two Centre hot dog resonators with anti-resonance chamber
• Varex rear muffler with twin 2.5″ outlets

VAREX mufflers combine both the design technology of the stock muffler and the performance muffler into one single compact unit. 

A sophisticated butterfly valve mechanism is implemented to re-direct the exhaust gas flow and vary between the two. 

For higher sound level, the exhaust flows are directed through the opening path and produces maximum power with a robust sound level (or the sports car note) and near 0 resistance. 

Whilst for lower sound level, the exhaust flows are directed through the chambered path (similar design with the stock muffler) and produces minimum sound level that gives you the best in car comfort. 

Angle of the valve is also controllable which can be adjusted to fully closed, half open or fully open for sports mode. This gives you further freedom to set the optimal sound level according to your desired preference.

The renowned VAREX Exhaust System was invented and manufactured by XForce Performance Exhaust.

VAREX exhaust has since been the most popular choice among the enthusiasts and professionals, who are seeking the flexible control of the sound level for their performance exhaust.

VAREX exhaust systems allow users to adjust the exhaust sound from stock-car like quiet to sports-car like growl by a click of a key fob button. 

We love our VAREX exhaust sound and performance, and we would prefer keeping the Varex exhaust on the “Open Mode” most of the time.

However, there is always some moments, the high volume exhaust sound is less desirable. We know that it is part of the nature of most performance exhausts.

Imagine the following scenario:

When you are cruising in a beautiful stretch of country road,  slightly tapping on the throttle pedal just to maintain the cruising speed, or simply let the cruise control taking over, most likely we would hear a low pitch, slight(or loud) humming exhaust sound resonating inside the cabin.Some of us might be fine with it, but to some, it could be a little bit too much to bear, especially during a long trip.

With Varex muffler installed,we could have reached for the Varex remote key fob, and quickly pressed the button to reduce the sound level. It is a good way to go, but yet not the most convenient one.

Angle of the valve is also controllable which can be adjusted to fully closed, half open or fully open for sports mode. This gives you further freedom to set the optimal sound level according to your desired preference.
