JBA 05-14 Chrysler 6.1/6.4L HEMI 1 7/8in Primary Raw 409SS Cat4Ward Header

If you're looking to get more power and better breathing out of your 2005-2014 Chrysler 300 with a 6.1L or 6.4L HEMI engine, these JBA Cat4Ward headers are a solid choice. They replace the restrictive stock exhaust manifolds with a design that lets your engine exhale more freely, which can lead to improved power and efficiency across the board. These headers are built from 409 stainless steel, a well-built material that holds up well to the heat and stress of daily driving and more spirited use.

JBA uses a proprietary Firecone collector design, which they say is proven on the track to help maximize power and torque gains where you'll notice them most – in the typical RPM range you use for driving. The primary tubes are 1 7/8 inches in diameter, and the flanges are a stout 3/8 inch thick with oversized exhaust ports to ensure a good seal and smooth flow. They also include factory-style connections for your emissions equipment, making it easier to keep your vehicle street legal, and come with high-quality hardware to help ensure a professional, leak-free installation.

When installing these headers, you'll want to have a good set of wrenches and sockets handy, and it's always a good idea to refer to the manufacturer's installation instructions for specific details. Because these are a performance exhaust component, you can expect a deeper, more aggressive exhaust note from your HEMI engine.
