Im getting a borla catback on my car and bought a couple rolls of Gt Mat Ultra for my trunk to reduce possible drone noise. I was also thinking about spraying down some Dei boom mat spray and then place the mats. Has anyone done this or should the mats in the trunk be good enough.

You'll want to cover the rear deck, top and bottom.

Or just buy some Solos

Keep in mind, adding all that sound deadening material is heavy and will add quite a bit of weight to the vehicle.

^Not if you use the light weight stuff

Your probably right. I have only ever worked with Dynamat, and a box of that stuff is quite heavy.
