Introduction

FAQs

Check your owner's manual; many manufacturers allow aftermarket mufflers that match OEM specs.

Quality mufflers can lower sound output by 5-10 decibels depending on engine size.

Many residential mufflers include built-in spark arrestors for fire safety compliance.

Remove the old muffler, apply high-temp sealant to threads, and torque the new unit to spec.

Automotive units often lack the correct inlet size and heat rating for generator exhaust.
