​King Quad 400 (2008-2020) HMF Performance Series

The Suzuki King Quad 400 is available as a Slip-On System in the Performance Series.  The Performance Series Slip-On system picks up roughly 10-15% more horse power and torque throughout the power curve.  The HMF Slip-On exhaust system weighs substantially less than the stock muffler, so you'll notice an overall weight drop.  The Performance exhaust will increase sound levels approximately 4-6 decibels above the stock muffler.

Equal Power: The Performance Series distributes power evenly throughout the entire RPM range.

2-10 dB Increase: Depending on the model, you can expect a 2-10 dB increase over stock.

Unrestricted Core: The Performance Series uses a 2 1/8" non-restrictive core for maximum flow.

Less Weight: The exhaust shell is made of T6061 Aluminum that weighs substantially less than stock.

The Insides: The Performance Series Exhaust system has an unrestricted core surrounded by high performance glass wool packing.
