In thin air, low internal backpressure can cause power fade, bogging, and slow throttle response; a stinger insert restores expansion chamber pressure to keep the engine in its power band. For drag racing, a tighter stinger heats the expansion chamber faster, cutting rev-stand warmup time. Two calibrations: one for the Patriot 850 and one for the high-revving 9R. The inserts drop into the Bikeman pipe for quick swaps and are precision-machined from high-temperature steel to resist warping and necking. Choose 01-328-H for elevations above 6,000 ft or for racing on a Patriot 850, or 01-328-9R for a 9R. Fits only the Bikeman Fatt Azz pipe (SKU 01-328); will not fit a factory Polaris expansion pipe.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e Polaris: Patriot 850 NA Long Track, Patriot 850 NA Short Track, AXYS 850.\u003c\/p\u003e\u003cp\u003e\u003cem\u003ePart # 01-328-9R, 01-328-H.\u003c\/em\u003e\u003c\/p\u003e\u003cp\u003eNot sure what fits your sled?
