Is it bad?

Dude, I get your point, this is a car forum.
You should see what I do when I get bored other times, which includes, but not limited to:
Shooting small game(squirls,chipmunks,birds)
Blowing shit up
Lighting things on fire with obscene amounts of gasoline
doing burnouts in or on what ever is in my garage.
getting on my front loader and building sweet jumps for my mini bike.
ect.

And, to defend my self, I had my car jacked up becasue I was powerwashing the mud and salt/sand that is caked underneath my car.
So I just decided to grab a 14mm and take off the 4 bolts and lower the mufflers off.

I’m not sure exactly what it is,but when i’m WOT in boost the car sounds like a god danm jet.
