I will take a guess that you need stiffer exhaust hangers (either NISMO or polyurethane aftermarket) or you need an extra hanger above the W-brace near the middle of the car that is for side impact.

Get the car on a lift or go underneath if you can fit (Rhino ramps), and bang on your exhaust while cold and see if it's hitting anything. Work your way from the cats down to the rear section exhaust.

This occurs in the NISMO exhaust due to the extra weight of the G35 extension and sometimes it happens on the HKS mid-pipe due to not a 100% perfect bend over the W-brace.

I put on a stiffer hanger and no extra hangers and it solved the problem.

Then again, it could be something else, but worth a shot.
 
Who installed it? Take it back and tell them theres rattles....probably need a slight adjustment, maybe its touching something.

Just got mine installed. Sounds great. It has a deeper and slightly louder exhaust note on acceleration, but not obnoxious. Not much louder than stock at idle or at cruising speed, but definitely deeper. No droning on the highway. There is a noticeable increase in throttle response at low to mid RPM ranges. Here's a before and after comparison on Youtube:

Does anyone know if the Invidia will work around a full GT-Spec brace set-up? Also Bklynjohn718 asked if the Invidia offered up better performance than the Nismo, any comparative input on this?
