just when ya think your done!!! well i put exhaust on the truck and it was dyno max turbos , outside they sound great but inside the cab there to loud, is this a sign of old age?

well i had a new rubber mat in it but had to pull the seat to put a new sending unit in it, so while i have it out i went ahead and ordered new carpet, i sprayed undercoating on the floor pans also. question is do yall think this will cut down alot on the exhaust or should i spend the extra$$ and get the sound deadner? thanks for any input, im dying to drive this thing and everytime i belive its done something else pops up or breaks etc etc,, of course yall know the story

and im waiting on all 4 new drums should be here by weeks end hopefully
