Berks HFC with nismo- rasp/rattle extremely loud -

To me it sounds like a broken restrictor plate inside the muffler. If it was something more upstream like a gasket it wouldnt rattle like that it seems lighter.

Op can you post up a start up and light revs when the piping is hot?

After removing all heat shields and checking all bolts the guy at the shop said the same thing - it has to be the nismo muffler - a chamber inside is messed up and only hear it at low load- but when under the car on the lift I hear all the noise coming from the middle of the car near the xpipe- *no touching of crossmember either.. So I took his advice ordered the topspeed axleback and I'm most likely going to add 2 packed 12 inch resonators.. Fingers crossed I can get rid of this embarrassing honda civic/tin can sound.. Today I almost parked my car it's so embarrassing..
