Ripple Rock Racers new RRR/Hindle SS Exhaust Systems are developed to produce maximum horsepower and maximum torque with our 4-2-1 Design. The system is designed to give full access to oil filter, oil drain and centerstand. Our systems are fully spring mounted as per the best race systems for quick installation and removal. Our super thin wall stainless steel construction is strong, extremely durable, rust free and super light. The complete system with muffler weighs only 10 lbs. These vintage exhausts come as complete systems with a choice of 12” or 16” Megaphone Mufflers. Either size muffler can be had with a classic tip or the slash/cut reverse cone tip at $699. The systems are also available as “headers only” which is complete less muffler at $550. The megaphone mufflers are tuned to work with our headers and provide a deep rich sound, the 12 inch is a bit louder than the 16” but either is fine for street use anywhere. Note – To help decide which muffler you would prefer look at the RRR/Hindle Megaphone Mufflers section on my website as these are muffler choices and tips (end caps) I supply with each system.
Test bike was a stock 1980 CB750F, no jetting changes were made just the stock exhaust was traded for the RRR/Hindle. We made approx 8 more horsepower and 4 ft/lbs torque over the stock system.
