It will make the exhaust come out those holes instead of the the tail pipe. Just take your vehicle to a muffler shop and have them remove your muffler and put pipe in it's place. No restriction means more flow which means higher performance, unless your talking about a 2-stroke then don't f with it.
NO...if you want to drill holes in your exhaust just to make it louder your only going to get a small grinding sound..not much of a difference..just makes ur exhaust sound like its about to fall off...BUT if you just simply buy a Glasspack for like 30 bucks and have it put on for like 40, or put it on yourself...then sound will not be a problem, youll have a nice grumble sound...as for performance exhausts..your paying for the internal part of the muffler system like the fiberglass and all the intricate crap.
start with your head A muffler with holes in it would sound like a muffler with holes in it, terrible. Drilling holes in the muffler would increase the chance of getting exhaust fumes in the vehicle which is a bad thing.
Pre-splitting holes are charged, whereas line-drilling holes are not. Pre-splitting holes contain less explosive than the rest of the holes in the blast area.The blast holes directly adjacent to the line-drilling holes are charged to about 50% of that of the rest of the blast area.The diameter of the holes in pre-splitting tend to be much larger than those in line-drilling. Pre-splitting holes diameter ranges from 50mm - 100mm for civil engineering purposes while larger holes are used (some larger than 300 mm) for mining.Line-drilling holes usually have a diameter less than 75mm.Pre-splitting spacing is about 10-20 times the hole diameter.Line-drilling holes are spaced about 2-4 times the diameter of the hole.The holes in line-drilling are spaced much closer together than those of pre-splitting.

Drilling holes in a straight line
Your duck is probably drilling. Drilling is when they use their bill to make holes on the ground. They drill to get food, but they usually only drill is they have water.
In early drilling of holes in glass garlic was used.
Drilling machines are designed for drilling holes using a range of drill bit types. Drilling machines are normally stand alone machines and are not portable.
