The Big Bear 400 is available as a Slip-On in the Performance Series. The slip-on exhaust system picks up 10-15% more horse power and torque throughout the power curve, and weighs substantially less that the stock exhaust. The Performance exhaust is typically 4-6 decibels louder than the stock exhaust, but the HMF Quiet Core insert can lower that 2-4 dB.
Fits: (00-12) Big Bear 400, YFM40FV, FR, 4WD
