This race designed system is made entirely from Stainless Steel. It is fully spring mounted in sections for quick installation and removal. The system offers full access to the oil filter and oil drain. Hindle’s unique 4-2-1 design allows for maximum horsepower and maximum torque. This RRR/Hindle system was dyno tested and produced 41.74 hp and 31.5 ft lbs torque at the back wheel. The dyno run was on a stock 1978 CB550 (fitted with pods, main jet upped from 100-105) and equates to 6 more horsepower than the bike produced when new (tested by Cycle World, produced 34-36 depending on model and year of test)! We only had time for one run but if jetting was finessed, still more power and torque is there for the taking.

The Stainless Steel design makes for a super light, strong and extremely durable exhaust system which will not rust. The RRR/Hindle Vintage Racing Exhaust System can be ordered as a complete system with a Stainless Steel Megaphone Muffler for $774.90 or can be ordered as Headers Only ($624.95). The Stainless Steel Megaphone Mufflers come in two lengths, 12 inch or 16 inch, and are supplied with either a “Classic” tip (pictured on bike in 12″ length) or a “reverse cone slash cut Megaphone” tip (end cap). In either case the cost is $250. The Stainless Steel Megaphone Muffler has a straight through perforated baffle core design wrapped with SS wool and ceramic cloth to insure long lasting performance. This straight through design lets the engine breathe yet is “relatively” quiet when trolling about town.

When the throttle is opened, the system produces a rich mellow sound as it screams toward redline, truly fantastic! The 16 inch Megaphone is a little quieter than the 12 inch Megaphone. The 12 inch is…a…robust in volume!! Note – to help decide on muffler length and tip, look at my separate section “Hindle Megaphone Mufflers” on page 1. These are the muffler choices supplied with each system Center stand must be removed to fit the system but the mounts can stay.
