You know me, can't pass up a cheap deal. For about $80 delivered I got these Dynomax over-axle pipes and the installs on youtube looked so straight forward. Since I was going to have the car way up on jack stands to do my brake upgrade the stage was all set. Don't be a dufas like me and my husband! Lesson learned no matter how high on jack stands you get the car you can't maneuver the pipes over the axle (without cutting and welding). Now I'm going to get an appointment at the base auto hobby shop to put this thing up on a rack. I have 75K on this so I may do the auto tranny pan drop and do new ATF fluid while up there too. Any good advice from recent ATF swap experts is appreciated. You can see on this driver's side angle why the "cat back" is better than the axle back systems.
