1/4" holes at the back plate of muffler...

This is what Chicago Tribune's Auto Mechanic section recommended. At the backplate of the main muffler, about 1" or so from the botton, make several 1/4" holes. When I did, I found there were already a few holes on my newly replaced Muffler (OEM, believe Napa's), so I added a few more holes there. As far as I'm concerned, however, major corrosion occurs on Exhaust pipes, flanges, bolts, attacked from road salt (at least in the snow belt), and when mufflers die, we have to replace most of the exhaust system (except CAT).
BTW, what do you mean "smoke" and where do you see coming from? If it comes from front end, there is a different story -- as you know, water condensation around the radiator and this happens when radiator fins are covered with vapor during night and when radiator warms up, it evaporates producing a lot of white vapor, which is sometimes mistaken as smoke. You say when the radiator fan starts the smoke disappers. This makes me ask this question. Cheers! DIY '93 900S 80K.
