I never had a dual quiet pack, but I suffered thru a number of singles until I gave up on them. They all seem to suffer from the same 2 problems: Their connections to the lower heat exchangers keep coming loose, because the tubing is a bit too large, and they always hit the underside of the body where they exit. As Bob already mentioned, they eliminate the rear heat exchangers, which means less heat, but that is seldom a problem for most of us. The bigger problem is the hoses that bypass the air to the lower heat exchangers. Those always manage to wear thru or fall off within a year. The OE mufflers really can't be beat for durability and quality, but they ARE a bear to install. Good ones even incorporate equal length header pipes, but they don't all have this feature. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
