disc of silence?!? how have i never heard about this
my car is waaaaay too quiet for me. how far in the pipe is it, and how do i get it out?
It came on some Dual /Dual systems from the factory. It is a disc in the drivers side tail pipe that has a little hole in it to allow smoke to come out so it looks like both pipes flow but it essentially blocks the drivers tail pipe to reduce noise.If you have it, It is located at the muffler outlet where it mets the begining of the drivers side tailpipe. To test and see if you have one, have someone rev the engine while you are back there and feel if both pipes flow equally. Like I said before at idle you will see smoke from the tip but thats just for show, you need to rev and feel if the pressure is equal between tailpipes.The second test is measure the length of the tailpipe from the muffler the run a piece of wire or coat hanger down it and see if it stops. Unless somehow you can unclamp that tail pipe , you will have to take it to a muffler shop and have cut off the tailpipe ,remove the disc then weld the tailpipe back on. Good luck,hope you don't have it.

magnaflow exhausts dont have this do they? because i noticed my driverside pipe is much quieter at idle and less is flowing from it
No, Magnaflow is a straight-through muffler with a kind of diverter inside. Under low flow conditions, most of the exhaust flows through the one pipe, and when flow increases, more is diverted to the other pipe.

I just ordered a Heartthrob cat back for 99 with longtubes and Y pipe. I will let you how it sounds. I know their HVS mufflers remove the drone and sound good.
