Exhaust help please!

First of all hey to everyone on here im new and just purchased a 06 TRD double cab 4.0L from a older man here in town and now i need some help. I know there may be another thread on here i tried to search for one but could not find it, but i really need some help deciding on what to do. I am looking at getting a new exhaust for it but i really do not want to spend a lot of money on and a deep nice sound is very important to me i cannot stand any "rice" nose to it at all. So i am looking at using mt stock pipes and putting a Flowmaster 40 on it. Any ideas? Experience? Suggestions? I am open to anything thankyou all for your help.

 

thanks for the fast response does anyone know what it will sound like if i do keep the stock pipes and just put a new flowmaster 40 in there?
