Huffer I ask for your audio based wisdom
now that I have a little guy I feel like the interior of my car is a little too loud mainly from the exhaust, and I really don't feel like redoing the exhaust ( currently OBX EL header -> "Busted" Hiflow cat -> obx resonator -> 18" resonator -> vibrant axle-back with 2.25" custom stainless piping ) I've noticed that when I had my trunk STUFFED with groceries and the wife in the back seat (with the baby) the car seemed quieter but from other trips, if i just have passengers in the back seat the car sounds louder.
I know my ears aren't a replacement for a good dB meter but is there anything dynomat and some good closed cell foam could do for me?
if i were to go this route where and how much of the stuff should I apply?
and If the projected cost is going to go over ~750 I'll just a new exhaust from the heads back...
suggestions?
