What is the best type of after market exhaust

[DirtDog]

I have an 06 Pontiac Grand Prix GXP with the 5.3L V8 N/A. I have been doing some work on it like cold air intake new spark plugs tranny filter change and all and im wanting to put a new exhaust onto the car for a better sound. The stock exhaust sounds good when idling or accelerating but not so much when going at a constant speed and all. I have never done any exhausts before on my other Pontiac and not for sure what kind is better and sounds better. Magnaflow or flowmaster or what brand would yall in the grand prix community think is best from experience.

Magnaflow seems to be the cat back of choice for a GXP.

ur gonna have a drone, so not much u can do on it, as for exhaust slp and borla are pretty solid, and magnaflow will also sound pretty decent on it since its a v8

I've always liked Borla or Magnaflow on a v8.
