Question Dual vs Single

This may be a stupid question, but here goes...
Will the dB level of sound (noise) coming from a single exhaust be distributed evenly (cut in half) if it were converted to a dual exhaust? Or will the noise level be the same?

Tough to say, it depends on so many factors... if you're eliminating the resonator, the size of the pipe, the properties of the mufflers, etc etc.

Factory cat (no resonator) is intact. 2-1/4 pipe going into a glass pack muffler on one side about 4 linear feet from cat (pretty loud). This is a dune buggy and it looks a little lopsided, (did I mention loud?). I was going to put a Y after the cat and run the left side pipe under and over to the other side with another muffler.

No, you will still produce the same amount of db, it just won't resonate as far if my memory serves me correctly since you will be reducing the restriction and dispersing the sound wave.
