JBA 09-20 Chrysler 5.7L HEMI 1-3/4in Primary Silver Ctd Cat4Ward Header

If you're looking to get more out of your 5.7L HEMI engine in your 2009-2022 Chrysler 300, upgrading the exhaust manifolds to a set of JBA Cat4Ward headers is a solid move. These headers are designed to be significantly less restrictive than the factory manifolds, which can help your engine breathe better, leading to improved power and efficiency where you need it most – during daily driving and towing.

JBA builds these headers from durable stainless steel tubing, and they feature 3/8-inch thick machined flanges with oversized exhaust ports to ensure a strong seal and good flow. The proprietary Firecone collector design is a key part of how these headers make power, using race-proven technology to maximize torque gains. You'll also find that they include factory-style emission connections, making it easier to hook up your stock catalytic converters for a cleaner exhaust system. The mandrel-bent tubing helps maintain consistent diameter throughout, further aiding exhaust flow.

When you're installing these, you'll appreciate that they come with high-quality hardware, which is crucial for a professional, no-leak installation. The extra-thick collector domes are also a notable detail that contributes to the overall well-built nature of these headers. If you're aiming to unlock more performance from your HEMI, these JBA headers are a well-considered upgrade.
