Would really like to see how the Monster shorty compares!I was not involved in any of the dyno runs. I sent all the pipes to a third party to avoid any problems. The Dasa pipe has made the most HP so far out of all the pipes we have run. I have 2 pipes left to test ...... the n-motion and the barker. I should have the barker pipe in 2 - 3 weeks. As soon as the barker arrives i will send the n-motion and the barker out to be tested. So if you are looking to buy a pipe now the Dasa is the way to go no doubt. It was pretty clear that the Dasa was going to make big HP. The Dasa pipe has alot of features designed into it to make HP. Dasa really does their homework when it comes to designing a pipe.
