I am new to this forum. I purchased a 2011 Jetta Sportwagen TDI. I had some minor modifications done to it as it is limited. I did purchase the BANKS Exhaust System for the Jetta Sportwagen and also replaced the air filter with a K&N. Noticeable torque, response and power. My question is... Since the introduction of the DPF and all the regeneration requirements, would the new banks hi flow exhaust cause premature clogging of the DPF?
