Construction & Design

Kooks utilizes top-tier T304 aircraft-grade stainless steel to manufacture these connection pipes, ensuring exceptional strength and resistance to rust and corrosion even under extreme operating conditions. Each pipe is meticulously handcrafted in the USA, reflecting over five decades of expertise in high-performance exhaust fabrication.

The design features OEM outlet sizing for a direct bolt-on fit, minimizing installation complexity and preserving the factory exhaust routing. Integrated catalytic converters balance emissions compliance with performance, while the built-in exhaust pressure sensor maintains proper engine management and diagnostics. This thoughtful engineering ensures enhanced exhaust flow without sacrificing system integrity or reliability.

Performance & Sound

When paired with Kooks Headers, these catted connection pipes contribute to a freer-flowing exhaust system that improves throttle response and overall engine efficiency. The inclusion of standard race catalytic converters allows for emissions compliance without the restrictive effects of traditional cats, resulting in a more aggressive and refined exhaust tone that complements the muscular character of the SRT8 lineup.

Drivers can expect a powerful yet balanced exhaust note that enhances the driving experience on both street and track.

Installation & Fitment

These connection pipes are engineered for a direct fit on 2011–2014 Dodge Challenger SRT8, Dodge Charger SRT8, and Chrysler 300 SRT8 models equipped with the 6.4L 392 HEMI engine. Installation requires the use of Kooks Headers, as these pipes are designed to mate precisely with those components for optimal performance and fitment.

The installation process involves standard exhaust system modifications and sensor connections. An EPS block-off plug is included for applications where the exhaust pressure sensor is not utilized. Professional installation is recommended to ensure proper fitment, sensor calibration, and maximum performance benefits.

What's Included

• One pair of 3" x 2-3/4" catted stainless steel connection pipes
