Hey all, my flex pipe has been leaking for quite sometime but Tuesday it decided to fail completely. Using a discount code at Advanced Auto Parts I was able to pick up the flex pipe and seals all for only $64.69. It beat RockAuto's price by close to $10 and I didn't have to wait for shipping.
I soaked all 4 bolts in WD-40 for 3 nights in a row. Each night I'd come out and spray the bolts down before going to bed. This worked out well as I didn't break a single bolt, which was my main concern.
You will need:
NOTE: The front nut looks to be welded to the flange, so I did not replace it or the bolt as they were in good enough condition.
- WD-40 or PB Blaster
- Walker Flex Pipe - Part 53421
- Walker Exhaust Gasket - Part 31374
- Walker Exhaust Gasket - Part 31332
- 14MM or 9/16 Socket & Wrench
- 14MM or 9/16 Box End Wrench
- Optional But Recommended : Toyota # 90080-17187 (NUT for Rear Flex Pipe Connection)
- Optional But Recommended : Toyota # 91512-81035 (BOLT for Rear Flex Pipe Connection)
Here's the old Flex Pipe, you can see where it broke:
First attack the rear bolts (14mm or 9/16), they are the most difficult to access. I had the most difficulty with the driver side rear bolt (the one with the socket on it):
Then go the front bolts (14mm or 9/16):
Here's the old nut on the rear flex pipe connection, there was just no way I was going to re-use this:
Comparing the old Flex Pipe to new Flex Pipe, ensuring proper fitment. As you can see they are exactly alike:
Gasket 31374 goes on the rear side, it's easiest to put the gasket onto this pipe first and then install it into place. I installed the rear side first, and then moved to the front:
Gasket 31332 goes on the front side, easiest to place it on the exhaust flange and then place the flex pipe onto it during installation:
Start the car up and check for leaks!
