This video will show you the process of removing the DPF from the exhaust whilst leaving the CAT intact.
If you do not wish to knock out your DPF, or wish to keep the DPF intact and put away to a safe place we have DPF Delete Pipes (we call them Race Pipes) available for Mazda, Nissan, Mitsubishi and VAG Golf
