I wondered why the heck high-performance EGR coolers were being sold for diesel pickups.
That's a NASTY fine catalyst/filter. Plus the swirl fins in the exhaust, and one can't help but to think the gains in ditchig this crap must be HUGE compared to a larger exhaust and deleted cat on a traditional diesel of the 90s. In both power and fuel economy.
