I got the flowmaster 80 on my car......She sounds great.....IMO. The stocker muffler is welded on the pipe, so you will have to cut it out.....It'* easy.

You're kidding, right?
Any F-body Crossflow muffler with the right inlet and outlet diameters will be fine.
You shouldn't lose any low end when gutting a cat, or putting a high flow one in..
Yeah it'* loud. I fired mine up @ 2AM with just a Cat and pipe.
It doesn't really sound bad, but it'* LOUD. I found my pix of a double glass pack setup, i'll get them up when I'm at home.

Gutting a cat is a bad idea to begin with for several other reasons. Keep the components, but replace them with higher-flow designs.
I have an 87 but i didn't want to start a new post. The 80 series will fit just the same on mine right? Jegs has it for like 90 bucks shipped. Not a bad deal. When you remove the old muffler does the new one slip in to the old inlet and can be clamped or does it have to be welded all around?
