JBA 05-09 Jeep Liberty 3.7L V6 1-1/2in Primary Raw 409SS Cat4Ward Header

The 3/8-inch thick machined flanges on these JBA headers are a solid starting point for improving your 2005-2009 Jeep Liberty's exhaust flow. These shorty headers are designed to be a significant upgrade over the stock exhaust manifolds, helping your 3.7L V6 engine breathe easier and gain more power. The less restrictive design means your engine can expel exhaust gases more efficiently, which can lead to better overall performance and potentially improved fuel economy.

Constructed from durable 409 stainless steel tubing, these headers are built to handle the demands of daily driving, towing, and even some spirited use. JBA uses a proprietary Firecone collector design, a technology proven on the race track, to help maximize power and torque gains in the RPM range you'll use most often. The tubing is mandrel bent to maintain consistent diameter throughout, ensuring smooth exhaust flow. You'll also find extra thick collector domes for added durability. This kit includes factory-style emission connections and all the necessary high-quality hardware for a professional installation that aims for a leak-free seal.

When installing these headers, it's a good idea to have a new gasket set on hand, as reusing old ones can sometimes lead to leaks. Refer to the manufacturer's installation instructions for the most accurate guidance on the process.
