Large round pigtail with two small square tailpipes

A large round pigtail with two small square tailpipes is a custom exhaust configuration where a single large round pipe splits into two smaller square outlets, combining aesthetic appeal with performance functionality.OverviewThis type of exhaust setup is commonly used in custom or performance vehicles. The main large round pigtail serves as the primary exhaust conduit, while the two smaller square tailpipes act as the visible outlets. This design allows for a unique visual style, often enhancing the rear appearance of the car, and can also influence the sound and flow characteristics of the exhaust system .Tailpipe Shapes and MaterialsTailpipes come in various shapes including round, oval, square, and slash-cut. Round pipes are typically used for the main exhaust line due to their efficient flow, while square or rectangular outlets are often chosen for styling purposes . These components are usually made from 304 stainless steel for durability and corrosion resistance, though mild steel or aluminized steel options are also available .Custom FabricationCustom exhaust manufacturers, such as Jetex, offer tail-trims and adaptors that allow a single pipe to split into multiple outlets. Clamp-on or weldable tail-trims can be used to join pipes that do not naturally fit together, making it possible to create a large round pigtail feeding two small square tailpipes . This setup can be tailored for road or track use, balancing aesthetics, sound, and performance.Performance and Aesthetic BenefitsVisual impact: The combination of round and square shapes creates a distinctive rear-end look.Sound tuning: Splitting the exhaust can slightly alter the exhaust note, giving a more aggressive tone.Flow efficiency: Properly designed splits maintain exhaust flow while accommodating multiple outlets.Sourcing OptionsYou can find components for this configuration from custom exhaust suppliers like Jetex, Weldracingparts, or stainless steel tailpipe specialists. They offer dual outlet tips, pigtail adaptors, and various tailpipe shapes suitable for creating this type of exhaust . This configuration is ideal for enthusiasts looking to combine performance with a unique, high-end appearance on their vehicle.
