Exhaust recommendation

[eagleguy]

I may have posted this question before or someone may have asked similar but here it goes. I have a 70 SS with a 396 and I believe Headman headers. I currently have a gentleman or sleeper exhaust and am looking to go a bit more aggressive while still being able to talk to the misses. My current exhaust is standard steel with some off brand mufflers that is actually in good shape. If I am going to do the swap and spend the $ I want the best bang for the buck. Am I better just having an exhaust shop make me something custom or should I get a SS system like Magnaflow?
