Need to quieten down a high-performance exhaust without sacrificing flow? AES Racing Mufflers are Australian-made, high-flow performance mufflers designed for high-powered street, drag and motorsport applications. Featuring a straight-through stainless steel design, AES mufflers help significantly reduce exhaust noise while maintaining the flow required by high-performance engines. They are an excellent choice for turbocharged, rotary and high-horsepower applications where a conventional restrictive muffler isn't suitable. Available in multiple bore sizes and body lengths to suit custom performance exhaust systems. Why Choose an AES Racing Muffler? Australian made High-flow straight-through design Designed for performance and high-horsepower applications Helps reduce exhaust noise without excessive restriction Stainless steel construction Suitable for turbo, naturally aspirated and rotary applications Multiple bore sizes and body lengths available Ideal for street, drag, track and motorsport applications Popular Applications AES Racing Mufflers are suitable for a huge range of custom performance exhaust systems and are particularly popular for: Mazda RX-7, RX-3, RX-4 and other rotary applications 13B and 20B rotary engines Nissan SR20, RB25, RB26 and VR38 Toyota 1JZ and 2JZ Barra turbo applications High-horsepower turbocharged engines Street and drag cars Custom 2", 2.5", 3", 3.5" and 4" exhaust systems Model Bore Size Body Diameter Body Length M1 4" 7" 500mm M1a 4" 8" 500mm M2 4" 7" 400mm M2a 4" 8" 400mm M3 3.5" 7" 500mm M3a 3.5" 8" 500mm M4 3.5" 7" 400mm M4a 3.5" 8" 400mm M5 3" 7" 500mm M5a 3" 8" 500mm M6 3" 7" 400mm M7 2.5" 7" 500mm M8 2.5" 7" 400mm Will an AES Muffler Restrict My Exhaust? AES Racing Mufflers are designed specifically for performance applications where exhaust flow is important. Their straight-through design allows exhaust gas to flow through the muffler while the surrounding packing helps absorb exhaust noise. This makes them particularly suited to large-diameter and high-flow exhaust systems where reducing noise without creating unnecessary restriction is the priority. AES Mufflers for Rotary Engines Rotary engines can be notoriously difficult to keep quiet, particularly with large-diameter exhaust systems, bridgeports and high-powered turbo combinations. AES Racing Mufflers are a popular choice for rotary exhaust systems because they provide substantial sound control while retaining a high-flow straight-through design. For very loud applications, an AES Muffler can also be paired with an AES Resonator to provide additional noise and drone reduction. Choosing Your AES Muffler Size Match the bore size to your exhaust diameter. Where installation space allows, the larger and longer muffler body provides more internal volume for sound control. For applications where maximum noise reduction is the priority, choose the largest body diameter and length that will physically fit the vehicle.
