Hey, all.

I just read a huge thread on vmag on pv mufflers, catbacks, etc., and I'm coming away with more questions than answers.

Maybe some basics would help me and any other lurking previously-non-gear-heads.

The term "catback" seems almost generic - what is it? What's it do? What is the catback that the PV muffler isn't? Just pipes?

Why would a muffler need time to break in? What changes... it's all steel, isn't it?

There have been changes in the PV in the last two years, though I don't know what... have any of the issues brought up here been addressed?

What's the resonator thingey for?

Is there a reason to get a bigger tip (other than, "what guy doesn't like to look down and see a bigger tip?")? If so, what does that tip actually do (other than visually)?

The "wheezinator" that people removed had to be put in for some reason to begin with - performance companies don't sit around and figure out ways to make their products annoy customers - so does anyone know what it was originally intended to do? Some have indicated performance reasons?

Thanks,
