HI i have gone from a 3 inch kakimoto cat back (extremely loud) to a 2.5 inch h&s after burner centre section non res and tsl group n back box sounds nice but i have lost a lot of power but noticed it blowing where the down pipe joins centre decat i have ordered the new donut gasket just wondering if the blowing would cause my power loss which is quite alot thanks very much
