I have 2x VAREX canons which were fitted to my 300zx. You can switch from a loud open rumble to a quiet stock sound with the flick of a switch from the inside of your car, perfect for late at night when you don't want to wake the neighbours. They have been sitting around for a while and have gathered dust, but as seen in 1 picture I cleaned an area of 1 to show they still will come up nice with a bit of love
