I understand there are aftermarket options for this part claiming better air flow with less bends and polished pipes.
Not sure if that would help anything on 6.0 powerstroke since engine has so many bends in the airflow already.
This pipe has few small ones for better clearance and it doesn't look as bad as those aftermarket companies are claiming.
5 stars, it's pretty heavy piece of pipe with good finish and perfect clearance.
Thank you BC Diesel for supplying original parts with best pricing around.
