My folks had a 72 GP Model J they bought new. It had such a distinct sound. A little rumble and tone, but not too loud. My dad put a NAPA system on it one weekend and when he started it, he hung his head in disappointment because it was so quiet. Six months later he went to the Pontiac dealer and bought a complete OEM system. This was my mom's daily driver, and she was much happier, as was my dad. And me of course. I am looking at putting a new exhaust system on my 72 and just wondered if anyone had suggestions for mufflers that replicate that sound. My engine is the original 400 and is all stock.
