- Construction: Heavy-gauge stainless steel throughout

The straight-through Monster muffler virtually eliminates backpressure from the catalytic converter back, delivering more power and efficiency while producing an authoritative yet civil exhaust note. The mandrel-bent construction maintains consistent diameter throughout for optimal flow, while the heavy-gauge stainless steel ensures long-lasting durability against corrosion and trail abuse.
