2.5T Downpipe

Maximize the performance of your 2021+ Kia K5 2.5T with the Maintec Performance Downpipe. Engineered specifically for the 2.5L turbocharged platform, this downpipe significantly enhances exhaust flow, resulting in noticeable gains in horsepower, quicker turbo spool, and a more aggressive exhaust note. Key features include an approximate 10–20 HP increase, reduced turbo lag for improved throttle response, and a deeper, sportier exhaust sound. Constructed from 100% handmade, high-grade 304 stainless steel in Korea, it ensures maximum durability and corrosion resistance. The true bolt-on design allows for a direct replacement of the factory downpipe without requiring modifications. This downpipe is available in two options: a catless (decatted) version for maximum airflow and performance, or a 200-cell high-flow catalytic converter version for balanced performance with reduced emissions. Fitment is confirmed for 2021+ Kia K5 2.5T turbocharged models only. Important notes regarding installation and emissions: The catted version may still trigger a Check Engine Light (CEL), while the catless version is guaranteed to trigger a CEL. ECU tuning is recommended to eliminate CELs and fully optimize performance. Please be aware that this product is not available for shipment to California due to emissions regulations.
