Show original supplier description
Maximize the performance of your 2021+ Kia K5 2.5T with the Maintec Performance Downpipe. Engineered specifically for the 2.5L turbocharged platform, this high-flow downpipe is designed to significantly improve exhaust flow. This results in noticeable gains in horsepower, a reduction in turbo lag for quicker spool and improved throttle response, and a more aggressive, sportier exhaust note. The downpipe features a true bolt-on design, making it a direct replacement for the factory component without requiring any modifications. It is 100% handmade in Korea using high-grade 304 stainless steel, ensuring maximum durability and superior corrosion resistance. Key benefits include an approximate 10-20 HP increase and a deeper, sportier tone under acceleration. Customers can choose between a Catless (Decatted) Downpipe for maximum airflow and performance gains, or a 200-Cell High-Flow Catalytic Converter (Shark Racing) version for a balance between performance and reduced emissions. It is important to note that both catted and catless versions may trigger a Check Engine Light (CEL). ECU tuning is recommended to eliminate the CEL and fully optimize performance. This product is not available for shipment to California due to emissions regulations.
