The RRR/Hindle system is a true race developed unit made completely from Stainless Steel and fully purge welded. The system is designed to offer full access to the oil filter, oil drain and centerstand and rear passenger pegs are retained. Our Stainless Steel is very light, similar to Titanium but much less expensive and because it is made in stainless steel, it will not rust and has an extremely long life expectancy. This race style performance system is designed to install and come apart very quickly for any maintenance needs. The whole unit is spring mounted from the headers back so it can come apart in sections for maintenance. The 4-2-1 design offers maximum torque and maximum horsepower and the spring mounting system allows the owner to custom fit the unit to their bike at the midpipe section by either swiveling it in or out to bring the muffler in tighter to the bike’s frame. The RRR/Hindle system ships with a choice of two Stainless Steel Megaphone muffler lengths, a 12″ or 16″ (extra $10) and come fitted with either the “Classic Tip” or the “Reverse cone slash cut Megaphone Tip”. A model specific muffler hanger is also supplied which adapts the system to all the F and K models. The actual muffler mount is located at the bottom/back of the muffler to keep the clean lines of the unit. NOTE – to help decide on muffler choice look at my separate section “Hindle Megaphone Mufflers” on page 2 as these are the muffler choices and tips (end caps) I supply with each system.
The stock RRR/Hindle system has a nice mellow sound but it’s not objectionable and thus perfect for heavily populated areas, or coming home really late at night! When you get on the power and make the bike rev, then the free flowing nature of the Megaphone Muffler really comes on song and the sound is gorgeous!! Both Megaphone Mufflers will use the same mounting point and thus are completely interchangeable. With the “Shorty” or 12″ muffler length, the sound is…ah…stirring! We also offer a noise suppressor that cuts the sound by an additional 4-5db.
This system fits all the Honda CB750 models from 1969-78

My modified CB750K6 has long muffler classic tip.
The fitment is tight and fits very well.
Important to mount in correct order, no abuse with hammer needed. It slides right on.
I had to re-jet completely since the engine finally could breath as it is modified to do.
This exhaust the best 4-1 my bike has had.
Amazing how silent it is when riding in legal speeds handling throttle with care.
Looking into the muffler it is a huge hole all in! Not strange it can breath and sing when twisting.
That will show, or be heard when using the throttle! Amazing deep sound that wake the devil in the rider!
The pipes are ultra light!
Good with stainless steel. I ran cyl 3 a little bit lean, bluish pipe. I used very fine used grinding paper followed up with chrome polish. It look like new again.
After a ride or 2, all 4 had the same beautiful golden color again.
Pipe surface easy to maintain, I guess steel wool can ve used too if bluish due to carbs wrongly jetted. Finer grit paper for scratches.
Highly recommended pipe!
Kemp at Ripple Rock Racers is very helpful and service minded!
It was a joy to order this exhaust
