Product Description

The aFe 49-91014 Atlas Performance Muffler is a universal-fit, aluminized steel muffler engineered to enhance exhaust flow and sound quality on custom or large-bore exhaust systems. With a straight-through perforated core and heat-resistant packing, this muffler reduces backpressure while producing a deep, throaty exhaust note during acceleration and a smooth, refined sound at idle - making it ideal for performance builds, custom exhaust setups, and upgraded cat-back systems.

Its universal compatibility means it can be used on many vehicles with a 4" diameter exhaust pipe, making it a versatile choice for enthusiasts upgrading their exhaust for better sound and throttle response. Installation is straightforward with clamp-on connections - no welding required - though fitment should be verified for your specific vehicle and existing exhaust layout before purchase.
