Modify OEM exhaust C6 - remove something?
My buddy told me about a post here talking about cutting a square into the main muffler body, removing a component, welding your entrance hole up and having a decent sounding exhaust. If this sounds familiar to anyone, can you point me in the right direction. I searched for key words, but could not find it - cheers!

If you have the link for the z06 exhaust mod, please direct, I'll search on those key words. If a connector pipe is not already "perforated" my drill and I can fix that! I am not afraid to experiment with the stock exhaust. If I mess it up, I would have replaced it anyway! Thanks guys and gals!

I know, seen pictures but why do you care, nohting you can do to change the sound (like the Z06) unless you want to do a complete rebuild and then you still have no bi-mode feature. They are scrap to most so get a set and cut them open

On the stock C6 muffler, open the muffler body bottom just behind the tail pipe tips. Drill or cut openings in the pipe body in the rear most muffler chamber. Reseal outer shell. This allows a direct path to the outlet pipe. The more material removed from the inner pipe, the louder the muffler will become.

If you look at the picture in post 11, the pipe area where C6 is written, that is the pipe to drill or perforate. That chamber receives un-muffled exhaust from the inlet pipe. When you drill or perforate the pipe to the tips, the exhaust that has not yet made the trip through the muffler has a path to the outside world,[the tips] . I have done this to my 06 , sounds better than stock, just slightly louder than a " touring" .
