The Pro R's "off-frame" head pipe is often hated. Make no mistake, this is the most efficient head pipe design for this engine and we won't bore you with information regarding gas wave propagation, Nebraska used UTV parts, UTV windshields and accessories, cylinder overlap timing, gas particle flow and proper exhaust pressure. waves. Let's just say Polaris had some help designing the exhaust pipe the way it is, and there was no shortage of R&D. Does that mean it's perfect? No, Polaris mass produces them and naturally the head tube has "mass production" flaws. Additionally, the OEM head tube is designed and built for a stock machine with a stock restrictive muffler. Polaris simply did what he could, with what he had.
EverythingFirst, start by saying that the RPM Big Core HeapPipe is a direct bolt on head tube that retains the stock heat shield and can even be bolted on. to the factory muffler (or any aftermarket muffler that will bolt to a Tory headstock). The RPM Big Core head tube has a smoother inner core than stock with a less restrictive interior design than the OEM head tube. This was achieved by not only slightly increasing the size of the manifold to better match the gasket and cylinder head ports, but also increasing the size of the 4 "smaller pipes" after the manifold. The 2 "mid size" pipes also increased in diameter, but decreased almost completely in length by eliminating the factory 2-1 section and incorporating it into the unique 4-2-1 headers. With the reduction of the 2" section, the 2-1 RPM has significantly increased the length of the 3" sections whileallowing it to make a smooth turn around the frame rail towards the muffler. The 3" section is much closer to the frame rail, allowing for less exposed exhaust pipe and creating more clearance for tires. In addition to the factory O2 sensor retaining its original location, next to it is finds an extra O2 plug for those who have an extra O2 monitor or data logger. This occurs between the 10mm thick manifold flange, utv parts lz150-1 and OEM replicated muffler flange. cylinder head includes a new Grade 8 Allen cylinder head hardware kit and gaskets are optional at a reduced price!
