Anyone take out exhaust packing?

I'd like a little more sound without buying a new pipe. Can you take out packing or anything for some more sound of the mean 600? Or does that mess with the fuel air mixture/backpressure?

The stock can is welded together. Even if you did cut it open and weld it back together, you would want to jet it to get more fuel to match the increased air flow. I wouldn't recommed modding the stock pipe

Thank you sir. That's what I needed to know.
