Pro Circuit 0132645A T-6 Stainless Slip-On Exhaust Muffler YZ450F

The Pro Circuit T-6 Stainless Slip-On Silencer (0132645A) is a performance exhaust muffler engineered for Yamaha YZ450F riders who want a durable, bolt-on upgrade over the stock muffler without replacing the entire exhaust system. Designed to install directly onto the stock head pipe, this slip-on silencer delivers a noticeable performance improvement at an accessible price point.

Built with a stainless steel end-cap and an aluminum canister, the T-6 Stainless offers the durability needed to handle the rigors of off-road and closed-course riding. Pro Circuit's precision TIG welding and machined aluminum muffler bracket ensure a solid, rattle-free fit. The asymmetrical muffler configuration increases packing volume for optimized sound attenuation and performance.

A removable USFS-approved spark arrestor is included, making it simple to transition between trail riding and closed-course racing without swapping mufflers. Note: this silencer does not meet FIM sound requirements for professional racing.

Key Features:

• Bolt-on slip-on design — installs on the stock head pipe
• Stainless steel end-cap for corrosion resistance and durability
• Lightweight aluminum canister construction
• Machined aluminum muffler bracket for increased strength
• Asymmetrical muffler configuration for increased packing volume
• Removable USFS-approved spark arrestor included

The Pro Circuit T-6 Stainless Slip-On is an ideal choice for amateur and recreational YZ450F riders seeking real performance gains and professional-grade construction on a budget.
