I have a friend who has a 289 Shelby Cobra with straight side pipes. You can hear that thing forever. He has lost a significant amount of his hearing because of the loud noise. Granted it is louder in his Cobra than it would be in your truck, but there would still be enough noise to do harm to your hearing. I am 72 and I have lost quite a bit of my hearing and believe me when I tell you to do everything you can to protect your hearing. It has to last you a life time.
I love a good sounding exhaust and have had them on most of my cars from the very first one, a 1947 Ford coupe. As much as I love custom exhausts I do not like loud exhaust systems. The bikers with their straight pipes have gotten themselves legislated out of a lot of areas.
Do a nice mellow system and then you can be happy and so can your neighbors. By the way, I have never had a straight exhaust system on any of my cars, trucks or motorcycles.
