I have a '09 G6 GXP (LY7 -- 3.6L V6).
Is there some way to make the exhaust sound more 'robust'? I'd like it to have a nice rumble (louder and deeper sound).
I'm guessing a different muffler -- which one?
Or, I've read that I could remove the resonator (and replace with pipe).
I recently bought a '09 Pontiac GXP. It has GM's LY7 engine (3.6 L) for my daily-driver.
I would like to customize the exhaust; it's lame, and I'm hoping to give it a more robust sound.
Also, I'm planning on customizing the audio system.
