Kooks 04 Pontiac GTO LS1 5.7L 3in x 2 1/2in OEM Cat SS Exhaust Conn. Pipes

Crafted from T304 aircraft-quality stainless steel, these 3-inch by 2-1/2-inch catted OEM connection pipes from Kooks Headers are built to integrate with your 2004 Pontiac GTO's exhaust system. They are designed to work with the factory catalytic converters, helping to maintain emissions compliance while improving exhaust flow over stock components. Kooks has been a leader in high-performance exhaust for over 50 years, with a reputation built on championships and records across various racing organizations.

These connection pipes are dyno and race-tested to help achieve maximum power gains for your LS1 5.7L engine. They are handcrafted in the USA, reflecting a commitment to quality and durability. While these pipes feature standard race cats, they are not intended for use in forced induction applications. This ensures optimal performance and longevity when used as intended with naturally aspirated setups.

When installing these pipes, ensure they are properly connected to your existing exhaust system. Kooks Headers backs their products with a limited lifetime warranty to the original purchaser, offering peace of mind with your investment.
