hass1500

Thats the one im going to go with im going to order it from complete exhaust should be by the end of next week, ill post up a review after I get it I may not have asked the right question yesterday to my friend because when I looked on the completeexhaust website, both the 2505 & 2506 are dual in/dual out. I just looked on my 09, and a "direct replacement" would be single in/single out. I plan on going to dual exhaust so I'll stop back in next week and ask exactly which muffler he plans on using? Maybe he redoes the pipe from the cats to the muffler so it is dual in, I don't know.

I talked to my friend at the shop today and he mentioned he installs more of the 2506 kind for that added sound. I have not heard one yet, but he stated it wasn't obnoxious, just louder when you step on the gas.

I was about to ask the same question. I talked to a friend of mine that owns a 4-wheel drive shop that said the only muffler he will install on a 6.0 is a flo pro because of the resedence in the cab the other mufflers will cause. He said there are 3 variations depending on how loud you want. Sounds like flo pro will be the way to go?

I think that is about the sound I am looking for. A friend of mine owns a 4-wheel drive shop so I'll probably have him install a custom system, but I think I'm leaning towards the flowmasters. I don't want to sound like the headers to glass packs, no tail pipes I had on my 70 chevy, but I don't want to spend a few hundred dollars to sound like stock either. Thanks for everyone's input.

I was thinking cat-back, but what is the benefit/cons of going true duals?

This is the first 2500 HD I have every owned and would really like to put dual exhaust on it, but was wondering what the best exhaust for the money would be? BTW it has the 6.0L. I really like the way it sounds now, not extremly loud, but you can definately hear it. I would like to pair this up with a cold air intake, but not sure if doing either of these will void any warranties?
