Exhaust is too loud

Oct 28, 2010 update on DEATHTRAP's 1981 Toyota COROLLA

The sprint car muffler help quiet the exhaust down some,but it is not enough. I came up with the idea to add on a poser muffler for stealth mode and open up a dump somehow. First step is to make the dump. I think it turned out pretty good. I used the blade out of an old throttle body. Drilled some holes in the pipe and installed the blade on the shaft from the throttle body and welded a tab on one side to control it. I cut a grove in the shaft on the other side to help hold it in place.
