Unbolting the muffler.

What kind of gains can be realized by unbolting the muffler from the cat back? I'm talking about for both N/A and Turbo engines. I know this is a popular "power mod" for both mullet boys and rice boys. Just wondering if it actually does anything, or is it mainly for sound. TIA

No gains...just sound (for near stock NA cars)

On the dyno with a ITR muffler on my car, i gained 3whp throughout most of the powerband. Good for the track, but you wont even notice it in everyday driving.
