| NOISE RESTRICTORS / POWER CONES Due to popular demand for these muffler cones for the noisey 4 stroke bangers i am now producing these to suit all mufflers. these cones have been tested and proven by some local dirt bike racers to not just be alot quieter than the stock muffler db,s [ noise levels ] but also no power loss. the design of these cones still allows for minimal back pressure with a flow through tunnel, example of fitting this cone whilst the engine is running = loud to quiet. if any of you guys are interested in one of these noise pollution breakers give me a pm with your exact internal i.d muffler outlet measurements.
