The Honda TRX 400EX exhaust picks up 10-15% more horse power and torque throughout the power curve. The Full System adds another 5-10% more horse power while the MX system increases performance for high speed racing. The mufflers will be roughly 4-6dB louder than the stock exhaust, but the Competition Inserts and HMF Quiet Core can reduce that 2-6dB.
