The EVO runs rich from the factory, and many of the aftermarket exhaust
systems do not stick out far enough to prevent soot and heat damage from
occurring.
This carbon fiber heat shield set will help preserve your rear diffuser and
looks fantastic!
Made from billet aluminum, this recirculating diverter valve dumps the charge-air back into the air intake system keeping external noise to a minimum. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably. $259.95
