switch blade exhaust house

Looks like something that should be on an infomercial at 1am right after the Slap Chop, "you're gonna love my nuts" LOL With the 9cm housing on the 351, its already quick spooling. I dont see the need for this part. If you want to mess with it, drill the waste gate holes out larger to help drive pressure.
 
This thing works very well. Gwoody on here has first hand experience with it.
