I agree with Mille Racer, Acer. Glasspacks are really constrictive above 3,000rpm. Magnaflow are my preference, engineered for extraction, but Flowmasters are good too. I know, a nice V8 exhaust rumble is great, I love it too. I guess we all do. The crossover pipe w/good quality mufflers works. I little more money, but you can get the sound you want and enhance performance. What about saving a few more bucks, get some good headers and full flow cats to go with the duals?

Here is one chart I found. Every forum you go on has a different best flow muffler. Get what you want. I look at flow charts and then check sound clips.
I think you want to figure on 2.2 CFM per Horsepower. So 300 HP would need to flow around 660CFM

Acer, I hope you have not put glasspacks on your truck yet. Mille Racer makes some good points. I really don't think they're a good solution, at all. Ask some experienced mechanics, ask here, but glasspacks are restrictive, especially bad after around 3,000rpm. I like the Magnaflow product, flowmasters are great but I like a quiet rumble and the Magnaflow stainless steel is really a long lasting solution. My $.02.
