Show original supplier description
The LP Custom Fab 2021+ Mazda 3 2.5L Turbo 3.5” High Flow Catted Downpipe is engineered to enhance the performance of your turbocharged Mazda vehicle. This downpipe features a 3.5-inch tube diameter, a high-flow GESI catalytic converter, and is constructed from durable 304 stainless steel. Constructed with precision, this downpipe boasts TIG welding for robust joints and a water jet-cut flange for a perfect seal. LP Custom Fab also notes that while tuning is not strictly required, it is recommended for optimal performance gains. This downpipe is explicitly intended for off-road/motorsport use only. It offers a weight reduction compared to the OEM component, with the LP Custom Fab version weighing approximately 11.05 lbs versus the OEM's 16.84 lbs. Compatibility extends to several Mazda turbocharged models: Mazda 3 2.5 Turbo (2021+), Mazda CX-30 Turbo (2021+), Mazda CX-50 Turbo (2022+), and Mazda CX-5 Turbo (2019+). Installation services are available at their shop; contact sales@lpcustomfab.com for details.
