All engines decel pop , it's just that the sound is contained within the pipes and dissipated by the baffles . One of the reasons the R3 pipes are so huge ! I get fully where your coming from having the pop tuned out , usually a 5% increase in fuelling at closed throttle , this for one helps cool the headers and in turn cuts down the pop . I am fairly certain tho , that your plugs will show a bias to the rich end of the scale . Not a bad thing , but as Norm points out , not optimal . This had been mentioned before, but short open pipes are also prone to reversion , a much louder flashier type of decel pop . Once again , this is reduced by the adding of fuel and the cooling of the inside of the headers preventing the now oxygen rich fuel mixture detonating from the heat of the headers . Personally , I like the pop and even more so the bright blue flashes that accompany it . I do find it can also be controlled by riding technique if in a sound sensitive area . But on the whole , I like to let her crackle and bang . It's hooligan and yes , I should have grown out of that by now !..Me too...i like it better when theres no banging going on.
We split a muffler open on an old petrol powered Austin truck one morning. I was about 19 years old and delivering meat to the butchers early in the morning. A girl was walking a dog on the footpath. There was three of us clowns on the bench seat in the old truck and i turned the key off while the driver pumped the gas pedal...of course when i turned the key on again...KABOOOOM!!!....the girl and the dog came off the ground i swear!!
The muffler split right along the join and we got our bums kicked!
I figure decel pop isnt good for the exhaust system.
