Snowmobilers with performance sleds have always been interested in accessorizing their rides – especially when they’re new. One of the most popular accessories has adding a “performance” exhaust silencer. For many years this meant, quite simply, “noise equals power”.

While that last statement might be true, the social acceptability of an aftermarket exhaust that generates increased power at the cost of increased sound (db) is dwindling – fast.

Many snowmobile jurisdictions in the US and Canada have simply outlawed all exhaust modifications. While this scrutiny does seem biased against the snowmobile industry, it’s time for a better way to get more power and lighter weight.

My point about unfair or unbalanced scrutiny of the snowmobile industry when it comes to exhaust noise, is 100-percent rooted in the reality over 80 percent of all Harley Davidson motorcycles are fitted with performance, low restriction (read: ultra-loud) exhaust pipes and for the most part, nobody seems to care. Go figure.

Enter the MBRP Quiet series exhaust. MBRP and its talented crew of exhaust designers have come up with a piece of sno-mo performance genius. After riding an 850 Polaris with an MBRP Quiet Series silencer this past weekend I’m very optimistic about the future of this product.

The Quiet Series silencer is a complete no-brainer to install on a Polaris AXYS 850 and a little more work on a Ski-Doo G4 850 or 600R. The stainless steel exhaust is beautifully made and comes highly polished and with everything needed for the install.

The net HP gain is not heroic , but is a legit one horsepower. However, the Quiet Series scores big points in weight reduction – it’s a full six pounds lighter than stock.

Here’s the beef. The Quiet Series silencer is just that – much quieter than any aftermarket silencer we’ve ever tested. At idle, through engagement and at trail speeds there is no, zero, zip obtrusive crackly or annoying resonance. None.

When you crack the loud handle out on the lake there is a definite difference in the exhaust note from stock.

Think of it this way. Corvettes come with legal-quiet stock exhaust systems. Despite this, Corvettes have a sweet, throaty, imposing tone all of their own. That’s the best way to describe the MBRP Quiet Series Exhaust silencer.

The time has arrived, my sno-mo-accessory-crazed Buds, to live in the now and get an MBRP Quiet Series silencer. For sure – you’ll make more friends and contribute to protecting our sport’s future.
