whynot Posted July 18, 2018 Share Posted July 18, 2018 so on my 99 legacy wagon, I put the exhaust together after working on the engine. I have a big leak at the exhaust donut. I have replaced it 2X and can not figure out what is wrong. The posts I see make it loo easy. Some you tube video says to put high temp rtv? any tips for when I take a shot at it again next week. Thanks Quote Link to comment Share on other sites More sharing options...

msmithmmx Posted July 18, 2018 Share Posted July 18, 2018 Which side did you put the springs bolts on? 1 Quote Link to comment Share on other sites More sharing options...
montana tom Posted July 18, 2018 Share Posted July 18, 2018 Yup Bennie; All the US issue cars have a fiber doughnut between the resonator pipe and the muffler pipe. Uses 2 spring loaded bolts to allow flex. Quote Link to comment Share on other sites More sharing options...
whynot Posted July 18, 2018 Author Share Posted July 18, 2018 (edited) I am trying to remember, I think the springs are on the side to the rear of the car, the beveled side, not the stub that holds the donut. I will check toinght Edited July 18, 2018 by whynot spell Quote Link to comment Share on other sites More sharing options...
lmdew Posted July 19, 2018 Share Posted July 19, 2018 You have to get all of the old stuff out. I use my 5 & 1 Paint tool and then a rasp to clean out the old stuff. It's a bit of a pain on your back but that's what it takes. The shoulder bolt will pull tight against the front flange. Spring is on the back side of the rear flange.

el_freddo Posted July 19, 2018 Share Posted July 19, 2018 Ah that flange gasket. I've never heard it called a doughnut before... make sure it's orientated correctly when out fit it too. Cheers Bennie Quote Link to comment Share on other sites More sharing options...
