i have an OEM sport design muffler and was wondering what would happen if i cut a small portion of the cannister and take out whatever is inside the cannister and weld it back up. has anyone done this before? i'm not sure what kinda sound it will make, but i'm pretty sure it will gain some horsepower since there will be no more restriction, right? i just came up with this idea because i don't have the money for a nice exhaust system and i really like how OEM sport design muffler look like. what do you guys think? let me know if this is a bad idea before i waste my nice looking muffler.
