We won't bore you with the hardcore engineering math regarding gas wave propagation, cylinder overlap timing, and pressure waves—let's just say Polaris did their homework. But is it perfect? No. It suffers from typical mass-production flaws and was bottlenecked to match a restrictive stock muffler. Polaris did what they could with what they had. We did it better.\u003c\/p\u003e\n\u003cp\u003eEnter the \u003cb\u003eRPM Big Core Head Pipe\u003c\/b\u003e. Designed as a direct bolt-on upgrade, this pipe retains your stock heat shield and bolts right up to the factory muffler (or any aftermarket muffler designed for the OEM head pipe).\u003c\/p\u003e\n\u003cp\u003eWe completely overhauled the flow dynamics to create a smoother, far less restrictive interior than the OEM pipe. We slightly increased the manifold size to perfectly port-match the gasket and cylinder head ports, and stepped up the diameter of the four primary pipes. The two secondary pipes are also larger in diameter but significantly shorter—we eliminated the restrictive factory 2-1 section and incorporated it into our unique 4-2-1 collectors.\u003c\/p\u003e\n\u003cp\u003eBy shortening that 2\" section, we were able to drastically increase the length of the 3\" section, creating a much smoother bend around the frame rail toward the muffler. This tucks the 3\" section much tighter to the frame, significantly reducing exposed exhaust pipe and giving you crucial extra tire clearance.\u003c\/p\u003e\n\u003cp\u003eBuilt tough between a beefy 10mm thick header flange and an OEM-replicated muffler flange, this pipe is ready for anything. We retained the factory O2 sensor location and added a secondary O2 bung for riders running an aftermarket monitor or data logger. Every head pipe includes a fresh set of grade 8 allen head hardware, with optional gaskets available at a discounted price.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey
