The AT3030L is a 3" i.d. inlet, 3" i.d. outlet with a built in Resonator. The AT3030L was designed for high-output gas engines. The original AeroTurbine® resonated design, the AT4040L, was first resonated muffler design for the general public. The demand for a Truck and SUV muffler followed quickly. The result is the AT3030L Resonated muffler. The AT3030L is the hottest new product on the Truck and SUV performance exhaust market today.

The AT3030L is the most versatile Resonated model exhaust we carry. The length and inlet/outlet diameters were designed to be compatible with 90% of the gas truck and SUV vehicles on the market. Even the standard 2 1/2" and 2 1/4" exhaust pipe systems can easily be bumped up to 3" on the inlet with a new 3" exit pipe being installed on the outlet for maximum performance. The AT3030L will give the performance and quieter sound that every Truck or SUV owner should expect from their vehicle.

The AT3030L is completely stainless steel inside and out. A built in Resonator before our patented Air Foil is packed with high temperature ceramic packing. The hand-polished stainless steel AT3030L will give you the look and feel that you want and the performance you deserve.
