It's important to keep some air flowing thru the heat exchangers. All the aftermarket systems I've seen include some hoses which sort of perform this function, but most of them are poor quality and fail or fall off quickly. It's worth putting some thought into a good solution. I used aftermarket exhausts for many years before going back to the OE style. The OE mufflers are a lot of trouble to install, but they fit and work better. No matter what you do, don't throw away the rear heat exchangers that you removed along with your old muffler. Those are expensive to replace and you just might change your mind someday. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
