No. The flapper valve has nothing at all to do with back pressure.Whill it be less powerfull at lower revs?
The flapper valve is only to control noise from the exhaust systemWhill it be less powerfull at lower revs?
Ani difference in noice or feel?Just did it, but I used a servo eliminator. I heard you can just unhook the cable from the flapper and it won't throw a check light. At least that's what I've read on the 1199 forum.
well I must say I am sold on this ... better sound and it feels smoother at lower revs. might have to get the duc.ee gizmo as worried about called end dangling around.Well it only took a few minutes to do and is a bit fiddly but long pliers is the way to go. No error messages / lights on dash at start-up and will go for a spin later. Only worry is the cable end just hanging there ..... it may catch on something .... will take a look to see if solution.
Find the cable / circular connector on the exhaust pipework on the chain side just above silencer .... turn the connector clockwise with hand and at the same time take the cable through the gap with a pair of long nosed pliers. Simples.How do u do this mod? any youtube vids? what tools I need?
I want loud exhaust.. so everyone can see me ..LOL that way I have less chance of getting hit by a car..LOL
