Just my 2cents worth of advice =P

The application has to be right, such as the volume of exhaust gas that the engine is outputting( modified engine? )

So not just where having more resonators but other factors affect the sound volume.

A Right size pipe also makes a significant difference as well.

Having a fuller and better flowing exhaust matching to the engine output would also reduce the noise level.

Stock: two cats and one resonator
Midpipe: two resonators only

Just clarifying what is actually under there.

Midpipe opens up the exhaust stream, so there will be a little more volume with it. Most everybody who's tried it liked it a lot. If you get one, make sure you get the anti-fouler with it so you don't get CELs.
