Replacing Muffler
I have a 98 that the pipe broke off near the mounting flange on the left side. I guess this is common?? How difficult is it to replace? What all do I need to do? I bought a pair of mufflers at a swap meet that were like new. Is their anything i can do to prevent this from happening again. Thanks

8 years out of a muffler system sounds pretty good but I am guessing it broke at the weld. If you kept that area clean or even painted it then it should hold up longer. These systems are so cheap to buy used though because people buy new catback systems and sell or junk the stockers. I have one in my attic that is only 4 months old in case I want to go back to completely stock. If I ever sell the car I will probably take the catback off and put the stoker back on.

) were the two different times the pipes broke at the weld. (cheap crap
) Whatever G.M. replaced them with are much better and stronger. I agree with the previous post that you can buy used replacements cheap enough but inspect the welds to observe any stress cracks or porosity. If you're lucky to get warranty replacement ones you will be in good shape but I don't know how to tell the difference.
