Replaced both exhaust doughnuts (7/16/21) 1994 Southwind Storm 28ft 454 TBI w/4L80E (no air pump/s)
Passenger side one blew while in southern Ca. back on the 11th July (my planned start day to return home). Replaced both but was unable to replace the springs and nuts. Roll forward...after returning to Renton, Wa. the passenger side one was nearly gone again. I noticed the nuts were bottoming out prior to applying tension via the springs to the flange-pipe allowing for a leak.
Pulled the pipe down on both sides again and replaced the springs and nuts. Also applied lots of copper seize on everything. Once done I started the engine a few times to heat cycle everything and re-check. All nice and quiet now.
Used Fel-Pro doughnuts.
Also have on order an EGR (electric driven) and a trans filter (will change the trans fluid).
