Downpipes - Decats - OPF GPF Bypass

Downpipes, decat pipes and DPF deletes, also known Cat or OPF Bypass , remove the catalytic converter or particulate filter while keeping the same shape and mounting points as the OE part.
Made from 304 stainless steel, they also retain lambda sensor and differential pressure locations for proper installation. On turbo engines, fitting a decat or DPF delete requires an ECU remap to prevent error codes.
Installing these parts is commonly referred to as decatting or DPF removal. They free up engine performance, improve throttle response and deliver a sportier sound. Suitable for tuned cars, performance projects and sports vehicles.

Important: downpipes, decats and DPF deletes are not legal for road use or technical inspection.
