Re: What muffler

I put dual 2" thrush glasspacks with no crossover behind the 4.8 in my '67. I have the tailpipes turned out just in front of the rear wheels. Has just a little rumble at idle and accelerating, and gets pretty loud under WOT, but they don't drone or fight conversation at highway speeds. Plus it still sounds like a nice old truck, I can't tell you how many times i have been asked if it is the original 283 or 327 when I pull in and park somewhere. The looks on people's faces are priceless when I tell them that its a 4.8 V-8 out of an '02 silverado and pop the hood to prove it.
