Hey guys. So I recently bought a 23 gmc duramax 6.6. I work it to the bone. It’s a very quiet truck. Looking for some options to really open it up. What are some of the first things I should do to it to be able to achieve a louder overall sound and maybe a flutter eventually. I already put 60k miles on it towing. I would really like a deep sound with that whistle. I’m new to duramax so go easy on me.

You will be opening up a can of worms doing that. And it’s not as easy as you think. The days of just throwing an exhaust on are long gone.

I plan on doing a lot of things to it. The whole exhaust system is one thing, from what I read a tune is pretty mandatory also
