Well after working on trying to get off the stock exhaust i just did not have the tool or the space to break the seal on the bolts for the hangers so i ended up taking it somewhere to have it installed Saturday morning. After the install i got in my car and reved it a little and it sounded great, still does but after a day of driving it around i am starting to get a hiss sound on decel around 2500 rpms not to mention there is a rattle that sounds like a bb bouncing around which could be something loose from the install. Has anyone around had this hiss with there exhaust that could lend a little help on how to fix, it seems to be getting worse. I will try and post a sound clip so you can see what i am talking about.
here is a vido of the sound
