Front Flex Exhaust Pipe Replacement, Toyota Corolla 1997 1.6L Engine(前柔性尾气管的更换)
Remove the two bolts at the tail end of the pipe (拆下排气管尾部的二个螺栓)
所需工具：
- Steel Wire Bushes to remove the rust around the bolts & nuts as much as possible
- PB Blaster, penetrating oil. WD-40 is NOT penetrating oil.
- Bolt Remover, left and general socket ratchet. A bolt remover is a special grip- tite socket tool, to remove severely rounded, rusted, and damaged bolts and nuts. Please note the thickness of the two tools. The space you can maneuver the tools is quite limit. The general socket ratchet doesn't work in my case.
This is a very tough job. You can image the difficulty when you see the rusty, rounded off bolt and nut as shown below.
