Okay got the tubi street installed late yesterday. It was nice and i test drove it around top down all seemed fine although i am thinking i should have gone with a louder system. We will see how i feel in a couple of weeks. I wanted to add some miles to break in the cats and while driving this am with top up i hear a swooooisg sound between 3200 and 4100 rpm only. This sound does not happen if i rev the engine to and over that point while in neutral. Could something have been missed during the install? Before i panic or take it in i thought i would ask the experts. Thank you in advance
