So from what I've been reading it seems like a few of you have baffles on your exhaust setups? I can't find anymore info about this so someone care to shed some light?

I looks like you're installing a switch that someone makes your exhaust louder/quieter?

How?

What involved/needed? How much does this cost?

Do you need the Corsa exhaust?

I'm going to an XLR from a Maserati so I've been hard to impress when it comes to exhaust note. Although I do love the sound of American muscle. Sometimes I wish my car was really loud with a deep growl, other times I wish it could be stealth. These baffles sound like a pretty cool concept so I'd like to learn more!
