Spent the evening reading with interest about the exhaust flapper valve fitted to one of my twin tail pipes - is it a no-brainer to disconnect and plug the vacuum line for better sound low down, or does the sound of it opening around 2500 rpm make for a better experience ? Or does it screw up low rpm fuelling ?
Thoughts please people !

Disconnect it and try it to see if you like the different sound. ;)
 
Thanks for your thoughts people, can't imagine it would unsettle the fueling at low rpm so will have a tinker over the weekend. Does seem rather pc to fit it in the first place !
 
Took a while to locate the control solenoid, anyway it's behind the left hand rear quarter cover inside the boot. Here's a pic to show location and mod - as you leave the pipe in place on the butterfly looks slightly neater.

I don't think people go to that extent, they just remove and plug vacuum hose.
 
Yep Wilko, agree they will. I wanted to trace the location of the solenoid so made sense to mod there when it was located. Hopefully the image may help others locate the solenoid if required.
 
my 1997 doesn't have it. And if you heard mine you would definitely disconnect
