Well it will give you some more power nothing to major tho. You should also get the after market manifold redcat sells for more flow. It sounds a little better in my opinion not really louder just a different sound. As far as the pipe poping out from the manifold try snuging the zip ties with plyiers you can get them alot tighter with pliers than your fingers and try putting the pipe as close to the manifold as possible. Theres also different pipe couplers that are longer and fit alot tighter that would work better.
