I am redoing my exhaust, replacing my broken dynomax with a flowmaster catback. My question if I reuse the same old pipe, between the h-pipe to the muffler, is the joint between the h-pipe and this muffler pipe likely to leak? If so is there some kind of gasket I can put in it? The pipe still fits over the end of the hpipe fairly snugly, but not with a whole lot of overlap.

Also, while I have my car on jackstands, I am considering trying to fix my oil leak at the rear main seal. How difficult is this to fix and about how many hours would be expected for the first time attempting this? I have a Haynes manual and a fair assortment of tools.


Thank for any help.
