They are pretty quiet, my intake is louder than the exhaust most of the time. When you get on it though you can certainly tell it's there. So if you are looking for attention this would not be the route to go.

The exhausts are being sold by Alan over at http://www.alternativemotoring.com/ you can search for Alternative on this board and see his for sale ad. Actually, go here

I got my exhaust and header from them, they are easy to deal with.
