Louder Duramax

[Sle7enn]

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.

Basically you legally can’t.

And we can’t talk about how to do it illegally.

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.

Unbolt the manifolds. Or drill holes in them

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

Talking about deleting in public forums is equivalent to trying to hire a hitman for your wife. I don’t recommend it

Depends on how much of a bitch she is
