If you can unbolt the muffler, do so and shake it.

I did that but not rattle or anything... I dont care how loud it is outside the car cause it actually sounds pretty sick, its just how loud it got inside the cabin... i might just add an extra resanator to keep the tone down inside the cabin...

as for baffels thats exactly what one my my friends thats a tech said... If I can figure it out I think this is a sign to finally man up and get a FI exhaust haha

I have the top speed true dual and I haven't put more than 3000 miles on it and both resonators were destroyed inside. I had my local shop replace them with a 3 inch single. Top speed is garbage their customer service is garbage and their parts are garbage. if I were you I would look into unbolting the mufflers and looking inside them and the mid resonator as well.

I would check if it is resting on the cross member close to the y-pipe. At first mine was not touching, then as the hangers streched over time it started to rest on the cross member and the exhaust got several times louder, especially inside the cabin as the viration is transmitted into the frame.

that was checked for when it was on the lift, I think im going to cut out the old resanotor and replace it with a magaflow 12' res... its just way to loud inside the cabin and the low bass coming from the exhaust is to much for a daily driver.

When you can get a full CBE for $400... You have a problem... They sound ok at best on day one, then they start rattling and giving weird sounds...

The cheapest I'd go is with a Megan exhaust, I have had/installed their 370Z exhaust on a totally different car (Infiniti FX50S), and damn the quality is good and it's still running strong with 8k miles...

Than again, OP, if you like it that loud (which by looking at the video didn't seem THAT loud,) enjoy it

Couldn't have said it better myself.
