    Default 6.0L What Exhaust To Get?

    Hello, I just recently bought a new truck, it a 2003 2500HD with the 6.0L Vortec engine. Right now its got OBX Long tube headers with high flow cats running true duals thought about 2" or 3" pipe up to a set of 5" stacks through the bed. This is the loudest truck I have ever heard. I am wanting to remove the stacks and get duals out the back at a 45 degree in the corner. What exhaust system should i get? I do not want to spend too much and I have been looking at the Flowmaster Super 44, 40 series and 50 series but i don't know what to get. Also i am probably going to want an X pipe to go with it. If you could help me out and let me know what would sound good with what i got, that would be great. Thanks

    The 6.0 Vortec is a great engine, love mine. Ever thought about a custom exhaust so you get exactly what you want? Off topic but was that hood on the truck when you bought it or did you do the installation? I've been looking for a cowl induction/ram-air hood for my '03 2500HD but haven't been able to find many for under $500.

    The Truck came with the hood on the truck when i bought it. He said it is a Cervini Ram air hood. I think it looks really good but seems pretty expensive $600. Here is the website I found https://www.cervinis.com/product.asp...1&id=1205#1173

    Yeah, the price is outrageous for a piece of metal with a little flair.
