These High Flow Precats from RV6 are a direct bolt-in replacement for the stock units. To make this truly plug-and-play, a provision is added for the EGR tube. They are made to work with stock or any aftermarket J-pipe - the best results are achieved when combined with an RV6 Long Tube J-pipe.
The Precats are made of larger tubing and feature higher flowing cats.
RV6 exhaust components are built to the highest standards. CAD & CMM modeling are used to ensure the parts fit to a light tolerance. This includes the design of a thick, smooth-flowing cast transition. The entire system, including tubing, cats, flanges, and transition is 304 stainless steel. The system is TIG welded by master welders, not before being backpurged to remove impurities and eliminate potential failure points.
