Premium Construction

The entire system is constructed of 304 stainless steel and meticulously TIG welded for outstanding appearance and durability.

• Mid-pipe: 3" stainless steel tubing with high-quality cast flange machined to accept factory donut gasket for leak-free installation. Flex section adds compliance to the system.
• Y-pipe: Features an all-new cast split section that divides 3" tube into twin 2.5" tubes, improving durability and longevity over welded splits. High-quality cast flanges resist distortion.
