Default Flapper off...........
Finally got around to cutting out the exhaust flapper and how I wish I'd of gotten to this sooner, really don't like the spring tension. But now it's off and over all the truck runs smoother...………..

I have heard of folks doing that as well as welding them open; I've also gathered that there is a round outer **** as opposed to the square one that I have...……..

hey, off topic but if your location is accurate we should meet up!

Otherwise, glad you cut that thing out. Im interested to hear if MPG changes with the more flow. Does she feel any different up top?
