The GReddy Supreme SP cat-back exhaust is specifically tailored for the 2017-2020 Honda Civic Si Coupe. This system is designed to improve exhaust scavenging, which is critical for the turbocharged 1.5L engine found in the 10th Gen Civic. By increasing the diameter and reducing the number of bends, the Supreme SP allows for a more efficient path for exhaust gases, resulting in improved throttle response and a more engaging driving experience.
The Supreme SP series is the pinnacle of GReddy's street-focused exhaust technology. It offers a perfect balance between performance gains and everyday usability. The system is designed to look as good as it performs, featuring a polished finish that complements the aggressive lines of the Civic Si Coupe. Whether you are looking to add a bit more character to your engine note or seeking measurable performance improvements, this exhaust system delivers on all fronts. Trust in the quality and engineering of GReddy to take your vehicle to the next level. Find this and more at GGCRACING.
