[IDEA] Stock Exhaust Modification

My uncle works for a car exhaust business in my area, and i asked him about making my stock exhaust quieter. He looked at my exhaust and had a curious idea that, on paper, seems worth a try.

Currently, the holes in the exhaust are flat at 90 degree angles. He suggested that if i get a drill and drill each hole bigger, and at angles, the exhaust fumes will be baffled significantly more and will travel through the baffle a lot easier.

I would have tried this already however i realised i would need to cut into my muffler and then reweld it, which i am not too keen on doing.

See attached picture for an illustrated idea.
