I don't know about Banks specifically. But, I did just install a 4" down pipe to a 5" straight pipe to the rear last weekend. I think it sounds great! But, the people being passed when it is between 2000 and 2500 might not like it! It get's a little loud in that range but for the most part sounds really throaty. About like a gas pick-up with Flowmasters on it. I love it!
