IRL B58 Gen 3 MaxFlow EPA Compliant 400 Cell Downpipe

Engineered for performance without compromising refinement, the IRL B58 Gen 3 MaxFlow EPA Compliant 400 Cell Downpipe is designed to improve exhaust flow, enhance turbo response, and deliver a cleaner, more refined exhaust tone while maintaining emissions compliance.

Featuring a high flow 400 cell EPA compliant catalytic converter, this downpipe is engineered to reduce exhaust restriction while retaining the functionality of a catalytic converter. The result is a performance focused upgrade for enthusiasts who want improved flow and sound without the excessive rasp, odor, and compromises commonly associated with catless downpipes.

Developed with IRL’s performance first philosophy, the MaxFlow downpipe prioritizes real world performance, fitment, and everyday drivability. Its high flow design provides a balanced solution for street driven vehicles and modified B58 platforms, making it an ideal upgrade for owners looking to maximize their setup without sacrificing refinement.
