The ecm will not care what you do with the exhaust as there are no sensors in the exhaust system. The ecm only cares about the incoming airflow to the engine.
This will make it louder but may or may not hurt performance. The other manufacturers of them expensive exhaust systems have tuned them to have the needed back pressure on the system while increasing top end performance.

I first gutted the muffler (way loud, can't hear yourself think), reinstalled the baffles and drilled a 1/2" hole through both, now a little louder than stock, sane.

I guess you wouldn't understand what it is like having a sled trail go through your neighborhood when guys run a loud can on their exhaust at 3am. There IS a reason this is policed.

I never tried it with the Baffles completely removed. But I too just drilled holes through each baffle using a 3/4" hole saw bit. Sounds a bit louder on the stand, time will tell on the trail....

Buddy gutted his this way and ya it was loud, had a real snap to it. He got rid of it and went back to stock, he said it drove him crazy. My excell was quieter to ride then his gutted Muffler. I think drilling holes in the pipes is a better idea. But hey you say you want to do it then you say you have already done it and its not loud. You ask, people answer, you argue! So I'm at a loss!
