When you have upgraded your 85cc engine to a big bore configuration, you need an exhaust that can handle the increased displacement. The FMF Big Bore Factory Fatty Pipe is specifically tuned to extract the maximum potential from modified 85cc engines, providing the necessary backpressure and flow characteristics to support increased power output.
The Big Bore Factory Fatty is the perfect complement to your engine modifications. By refining the expansion chamber geometry, FMF ensures that your big bore kit performs exactly as intended, preventing the power loss often associated with using a stock pipe on a modified engine. The raw steel finish offers a classic, race-inspired look that is synonymous with FMF quality. This pipe is built to be durable yet lightweight, ensuring it can handle the intense demands of competitive racing. If you are serious about winning and have invested in a big bore kit, don't settle for anything less than an exhaust system designed to support that power. Trust GGCRACING to provide the high-performance components your bike deserves.
