The 27won downpipe for the Civic Si and Base Model 1.5T Turbo Engines L15B. This downpipe is a quality crafted piece which is built for enhanced efficiency and airflow, allowing a more efficient exit of exhaust gases, giving an increase in horsepower and torque. This downpipe comes with a high-flow catalytic converter, which is a 200 cell unit, this however still requires off-road or sanctioned racing events only. 27won has put in great work on all their products to emerge as a quality company who creates quality products. This downpipe is a great mixture of price to performance value and fitment and install are top notch. The inlet and outlet flanges are crafted using investment casting techniques with T304 stainless steel, ensuring high-quality construction. To guarantee long-lasting and resilient performance, the stainless steel piping and brackets are meticulously TIG welded with precision, resulting in a durable downpipe. The unrestricted downpipe delivers a noticeable increase of 7 wheel horsepower (wHP) across the 3200rpm to 5400rpm range, requiring no adjustments to the tuning. The 27WON Street-Catted setup offers impressive power gains on its own. However, when paired with custom tuning, the downpipe truly excels, showcasing its full potential and performance. 27won also offers a frontpipe that we highly suggest adding to your order so you have a complete system.
