First off I have the B&B dual quad 4.5 inch tip exhaust on my 02' WS6 Trans Am! And the sound is perfect not to loud on the drone while crusing and on the gas but as soon as you drop the hammer it comes alive! Now I think the owner before me put flowmaster mufflers and custom mufler shop pipes and it is way to loud and raspy for my taste. I think I will go with the B&B dual exit out the rear exhaust on the SS How do the people that have the rear exit like it so far?
