I don't know what exhaust to get for my 67 pontiac firebird?

[Lucas G]

the engine is a 400 ram air. i have 4 tube hedman headers on it. it has the x-pipe from the exhaust kit i got not to long ago that i want to keep. by the way never buy exhaust systems from Pypes, they sound bad. i'm thinking of the flowmaster super 44 mufflers or the flowmaster 50 series. i also am thinking about magnaflow but i don't know which to get. i want a raw aggressive sound both in idle and accelerating.

so you are really asking what muffler to get since you already have an exhaust system? The flowmaster site explains the difference between their mufflers. Cannt tell you how they compare to magnaflow

The muffler websites should have sound clips.
