i am buying one of those for my 2007 GT500 Shelby.
with a factory 1000 watt stereo system i am sure i can make my car sound old school. it will be funny to see the looks on people faces when i go to a cruise
I have GM chambered exhaust on my LS6 car with headers and nothing sounds better.at the ends of the chambered exhausts INLET and OUTLET there is a factory reducer/washer plate that restricts the flow of the exhaust.when you look indside they kind of look like big metal washers welded on.
you can drill them open with a large drill bit to get better exhaust flow and more power. just dont gun it when your around cops as they are very loud.
i love the sound as it is very unique and nothing sounds better than chambered exhaust with headers but my neighbours hate me

Look closely at the attached photo,you can see my chambered exhaust looking nasty !!
