Kooks Universal 1 3/4 x 3in SS Coll w/9-10in Long Body. Plus 2in for Slip

This Kooks 1-3/4 inch inlet by 3 inch outlet slip-on collector is crafted from 304 stainless steel, a strong material that holds up well to exhaust heat. It features a 4-into-1 design, meaning it takes four primary exhaust tubes and merges them into one outlet. This design is often chosen for its potential to improve exhaust scavenging, which can lead to better engine performance.

What sets this collector apart is Kooks' patented scavenging spike inside the collector. This internal spike is designed to help direct exhaust flow, promoting a smoother merge and potentially increasing exhaust velocity. The inlet has a 1-3/4 inch inside diameter, intended to slip over 1-3/4 inch primary tubes. For secure installation, it includes two A/B style tabs that attach to the primaries.

This collector is manufactured in the USA by Kooks Headers and Exhaust, a company with a long history in performance exhaust systems. It's built to be a durable component for custom exhaust builds where merging multiple primary tubes into a single outlet is needed.
