Years ago, I put a 440 into my '68 Valiant and had fenderwell headers. I learned a lot from that project, and it was loud. Did I say it was loud?! The joy of being really loud will wear off quickly as your brain rattles, so plan on what it will take to get nice mellow mufflers with the exhaust fully out the back. You will still have a nice throaty tone without being raspy. Have fun!
