Exhaust - Muffler replacement.

When I purchased my XB I found that the check engine light was on.  As a standard practice I take my snap on Ethos scan tool with me when looking at used cars.   I found that it had P0420 for a Catalyst below efficiency code.   The car has over 200k miles so I expected that the catalyst would be bad.

I purchased the catalyst, resonator and the muffler so as to be sure to replace everything in one swoop.   with this high of mileage I might as well do it now rather than piece by piece.   

The first item I replaced was the Muffler.  I purchased a Walker 54602 Quiet-Flow Stainless Steel Muffler Assembly from Amazon.com.  It was pretty quick delivery and only took a couple days.

It fit very well.  The rubber hanger are in the right location as the factory ones.   The assembly is the correct size and fit into the same spot without issues.   The coupling to the factory exhaust system was spot on.   I reused the old factory clamp and gasket for now because I will be replacing the complete exhaust system one my replacement oxygen sensor arrives.

Couples to the factory pipes without issues. 

Muffler fits into the factory location without issue

Exhaust hangers are in the right locations.

I noticed that the muffler tip does not reach to the back of the bumper opening.   So a muffler tip will be needed.  Otherwise the exhaust fumes will just gather under the bottom and swirl with the turbulence and possibly come back into the passenger compartment with the windows down I would think.

Muffler tip not long enough.

Be sure to use a lubricating oil on the rubber exhaust hangers to be able to slip them off the factory barbs.   It is pretty tough to get off without it.   The flare on the tips are pretty big.

I preparation for the exhaust replacement I sprayed Kroil on all the exhaust nuts and bolt to get the rust soft, then I broke the bolts loose and re-tightend them.   Now Im ready to go once everything is here.



Tools used to replace the muffler.  Lubricating oil, Pry bar. 12mm socket, 3/8 drive ratchet.

Tow hitch install

So I like to mountain bike ride at various locations.  On my last car I installed a tow hitch.
I searched Craigslist.org and Amazon.com

I found a junk yard here in Arizona with a scion that was wrecked.   Its a pretty friendly yard and you can pull your own parts or ask them to pull them for you for a charge of course.

I went to see how many parts I could find for my xb.  I needed 2 rear seat head rests, the drivers side fender inner liner for sure.  Optional items I was looking for was a tow hitch and catalytic converter.   

I found 2 good seat heat rest, the inner liner, and luckily the junk yard car had a tow hitch.  For 50 bucks I couldn't beat it.  So I went back to my car and brought my tools.  Well I brought my electric 1/2 in impact gun.  But forgot all my sockets.  Luckily I had my adjustable wrench and was able to use it to break the bolts loose and bring the hitch home.  It is a CURT Trailer Hitch   I brought it home and installed it to my XB that night.   

1. I removed the stock tie down hangers at the rear end. 
2. I had to remove the rubber exhaust hangers to lower the muffler down to gain access to install the hitch.  
3. I then raised and installed the hitch using the bolts supplied with it from the junk yard.  
4. I then re-installed the muffler to the rubber hangers.   
5. Basically, that all it takes to install the hitch.   

Bolted to the frame in place of the rear tie down hangers.

Time to install - approx 45 min.   On my back in the driveway, with the wheels on the ground.  Could be down faster if you put the back end on jack stands.

Tools used - 14mm socket for the hanger bolts, 17 mm impact socket for the hitch replacement bolts, lubricant, pry bar, impact gun.
