A flow master 50 series or a 40 serious depending on how loud you want. If you want the flowmaster chamber sound.

Most muffler shops will be able to advise you. There is still the old glass pack, they worked for decades. Boring I know it's more fun to say Borla.

Any straight through type muffler (magnaflow,dynomax ultraflow,Borla Pro xs) will give you more sound and better flow. Even the Flowmaster FX is an affordable straight through muffler. Longer case =quieter and shorter case = louder.

If you're looking for a mild sound, a Borla ProXS is a good option. I had them on my C10 for the first version of the exhaust
