Re: Exhaust quick disconnects
Back in my 280Z day I saw a setup where the guy put in a T..... the straight through portion (for minimum restriction) was the open pipe for the track, and the side (the base of the "T" if you will) bent around and through the muffler. The plug for street use was a bunch of rubber washers (a stack maybe 2" long and a diameter that just fit inside the pipe) with a metal washer at each end, and a bolt through all. He put it in, and tightened the nut, compressing the stack so it expanded to fill the pipe..... just like an expanding boat transom plug. Since the plug was several feet behind the T, it never got hot enough when closed to hurt the rubber. Simple and cheap.
But if we LEGALIZE it, we can't take your HOUSE!
