Description
Schoenfeld’s tri-Y design optimizes exhaust scavenging for dirt late models, delivering measurable gains in mid-range torque and throttle response when tuned properly. The stepped 1-7/8″ to 2″ primary tubes balance backpressure and flow characteristics across the RPM band, while the 3-1/2″ collector provides efficient gas velocity control. This is a bolt-on kit engineered specifically for Small Block Chevy circle track applications—no custom fabrication required.
