My 89 180SX makes some kind of rattle noise at 2,500rpm's. Strange because it only does it at exactly 2,500rpm's, any lower or higher rpm and the noise is gone. The noise seems to be coming from the hatch rear near where the glass and the roof joins. My guess is that it has something to do with the frequency from the exhaust but I have no clue. I have recently XS dual N1 exhaust but it is installed securely in the places so I really have no clue. Any ideas?

^Both.

As long as I rev it up around 2500, the rattle noise would come out from the back of hatch. Any ideas?
