FlySig Posted July 9, 2011 Posted July 9, 2011 Good morning all, new member here from Salt Lake City, Utah. I'm trying to repair a drilled out exhaust on a 1988 Route 66 250, now called the Virago 250. A previous owner drilled numerous holes in the rear of both mufflers, and now it is just too loud. There are too many holes and overlapping holes to put screws in. I'm thinking some kind of filler with a metal patch screwed on. This is a DIY project with the goal of being cheap. I am not a welder. Used pipes can be found for around $100, a last ditch option if necessary. Anybody have any experience or good ideas?
slice Posted July 9, 2011 Posted July 9, 2011 Hi Flysig, It would be nice if you said Hi in the new members section otherwise people will get grumpy with you and ignore your request for help, it's usually people who want advise and then we never hear from them again! As to your problem why don't you try an exhaust bandage, usually comes in various lengths and can be screwed into place before it sets, you will have to use an electric heat gun if you want it to work properly as they can take hours to dry otherwise. Just wrap it around the exhaust (sorry) muffler, it won't be pretty but it will be cheap.
Moderator Airhead Posted July 9, 2011 Moderator Posted July 9, 2011 yeah I would cut a suitable disc from metal and screw it on the back with exhaust paste between that and the exhaust http://cgi.ebay.co.uk/Holts-Gun-Gum-Paste-EXHAUST-REPAIR-200g-/160350398928

First I put some muffler goo over the holes. I think it is a high temp silicone. Then I put some wire mesh on top of that and coated that with some more goo. Then a metal disk cut from a thick tin can screwed over the top. There were so many holes already in the pipes that it was difficult to get the screws to really grip, but at least a couple seem to be pretty firm. It took several hours of fiddling around with it yesterday. This morning it will go back together and I'll take it for a ride to the grocery store to see how it holds up to pressure.
