That would be my suggestion to increase sound.
That's the X pipe I have but run it with AWE track. Had the Xtreme mufflers on it but it was too quiet for me. My car is a non npp car so I have no valves. Single tips out the back. Looking to do a header system soon and I'll sell at least the X pipe.

The biggest bottle neck in the 6th gen Camaro exhaust is just in front of the primary cat pipes where it necks down under 2". So if you are going to go through all the trouble of messing with the exhaust you might as well gain some power too while you are at it. Note this will require a tune.

Hey King, have you actually seen the Bullet pieces? I have found them through search a while back but it looked kinda scammy
Any experience?

Yeah dude your options are basically...
Finding an X pipe that still gets rid of the secondary honeycomb.
Finding a primary honeycomb sayonara.
Doing those 2 things separate or combining the 2.
Or the header route which there's a few ways to do that also.
Does your head hurt yet?
Also, it's a hit or miss going with anything but ARH, Kooks or Stainless works. So you'll be spending some loot if you wanna cover your bases.

If I knew when I'd have my Corsa double X off the car I could sell it to you if that's what you wanted but not sure what I'm doing exactly yet
