I have a 67, with a 400. I Have 2 1/4 inch exhaust all the way back. It is dual exhaust, but the mufflers are old glasspacks. They sound mean and nasty. Although they drone like a bitch and are obnoxiously loud. Is there anything that I could swap in there cheap?? Anybody have any suggestions?

If it's any help, I have a set of Raptor 2 1/4" turbo mufflers on my mild 455 75 bird without any crossover. They are reasonably quiet and were pretty cheap. Durable too, I've had them for about 7 years.

Hi,
I had one of my mufflers rot out and I had it replaced with a Walker 2.25" inlet and outlet. Sounds like stock. Mike

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
