flapper

Does a slip-on delete the cats and flapper?

For those of you who put on aftermarket exhaust (full systems) on and removed the flapper valve on the V4 how much torque did you lose in the low and mid range? If you did not Dyno it please let me know how your Butt Dyno felt. Im debating on the full system for the V4 but i don't want to lose...

Disconnecting Exhaust Motor Valve Hi all, is it possible to simply unplug the exhaust valve connector on the V4 without it throwing a check engine light? I did this on my previous Panigales and never had an issue, but have read mixed reviews here. I'm not trying to mechanically disconnect...

I know this topic has been discussed on here, I mentioned to my dealer it's been said that disconnecting the cable from the servo may reduce heat build up? He says no it will make no difference? And it may throw a code? Guys what's the consensus to removing the cable from the valve ? I see the...

Well here is the story. Im looking to put a slip on kit and remove the flapper assembly. Im not really finding any definitive info on whether or not that combination absolutely needs an UPMAP installed. its just the oem header pipe and a different can, not sure why upmap is needed. Never had to...

Gents, I've been having symptoms on my bike for about 2 weeks of being extremely down on power, cylinders cutting in and out, low noise, rough idle etc... Thought it was bad gas, but drained the tank and replaced with fresh fuel to no avail. After some googling, I thought the symptoms might...

There is always a lot of interest in the flapper valve so I thought I would post a couple photos so people can see what it actually looks like. These photos have been posted before but it is sometimes hard to search to find them. One shot the valve is open in the spring loaded default...

do either. that spring isn't strong enough to hold the butterfly open at full power. I was *planning* to do it but didn't get around to it. that just wasted an hour on the dyno :(

you, Sir, are wrong : """Located before the rear mufflers is a butterfly valve. It's probably used for the Engine Brake Control at the minimum and maybe for the traction control too.""" 2nd to last pic on the page. Ducati 1199 Panigale Close-Up From a Nerd's Point of View there's a...

Guys, Looks like the exhaust flapper valve is stuck in the closed position. I've not done any mods. I'd like to disconnect but it looks like the cable won't retract into the tube. Where is the other end? Can anyone show me how I might be able to fix this myself?

I searched and read a bunch of posts but have found conflicting answers. Does anyone know for sure if the entire flapper motor system can be removed without a CEL? I ask because I put a racebody on and ditched the servo but also had a bunch of stuff apart, and now I have a CEL. I would consider...

has anyone here actually done a self-install on the termi's and left the flapper valve in place? The ebay vid shows it being removed both internally and externally, I think that the 2012 flap stays open when you disconnect the cable but have not had the exhaust off to check. If so theoretically...

I reconnect the flapper valve when taking the bike to the dealer for service work and last time when I did it I could not remember which hole to put the cable end into. This is the correct position in the photo so just thought i would share here on the tech section for anyone else that ever...

Has anyone noticed the flapper valve is open at start up (when it should be shut to help noise tests) and then at around 3200rpm it shuts when cruising or going down hill and only opens after you open the throttle some way which causes it to suddenly open and lurch forward! not good and is a...
