I guess, technically, real Tercels do not have just mufflers. But, in 2012, my health had slipped to the point where I thought that I needed to find a local auto repair shop that would responsibly and conscientiously care for my Tercel. It was obvious that my Tercel would need a new muffler to pass state inspection, that year. Past experience taught me that old exhaust system parts could be a challenge to remove, if one did not have a torch.
Some years prior, the genuine Toyota mid-pipe/muffler combination that I had installed years earlier needed to be replaced. Whether it was because genuine Toyota pipes were no longer available or too expensive, the auto shop that I was using then put on a Walker mid-pipe and a separate Walker muffler. So, in 2012, it was just the muffler, with a single clamp, that needed to be replaced (so much for the Walker lifetime warranty).
Having moved to a new area, traveling to my previous auto shop seemed way too far. Because of my health concerns, I decided to give the local auto shop that my wife took her car to a try - they seemed reasonably fair - or so I thought.
I arrived at the shop with my Tercel, at the appointed time. There were windows in the wall, between the waiting area and the shop and the mechanic pulled my Tercel into the bay closest to the window-wall.
After getting my Tercel lifted, I watched the mechanic remove the muffler clamp then gently wiggle and wind the muffler off of the pipe. That took all of 15 to 20 seconds. Then the mechanic disappeared - apparently the food truck had arrived around back and it wasn't even lunchtime, yet.
I waited and waited and waited and kept wondering why it was taking so long to slide on a new muffler, clamp it, then give me back my car. I must have waited an hour for this simple process that should not have taken more than a couple of minutes.
Finally, the guy finished the job and got my car off of the lift and I thought I would just pay the bill and go home - that was until I learned that they charged me $192.88 (US)

Before deciding to take my Tercel to this shop, I learned that the NAPA store would sell me a new Walker muffler for $49 (US) - the exact same NAPA store and the exact same muffler used by this shop. I expected the shop to make 'some' profit on this but they charged me $84.46 (US) just for the muffler, $20 (US) for the clamp, and $77.50 (US) for labor (plus sales tax). It was amazing that I did not seize up right there on the spot.

To get my car back, I had to pay the bill. Then I went to the NAPA store and had the counter guy write down the retail price of the muffler on their business card. I took that back to the shop owner/manager but he would not concede that I had been ripped-off. It turned out that they charged me the "shop" or "job" rate for removing and replacing a genuine Toyota pipe/muffler combination, not for the simple muffler replacement that they actually did.
As I said early, I had previous installed a genuine Toyota mid-pipe/muffler combination on my Tercel 4WD - and it was a bear-and-a-half. I not only had to unbolt the rear shocks but had to use a mountain of blocks under the rear bumper to jack the car high enough for the rear axle to drop down enough to wrestle the pipe over the axle. Whew! What a project! Ain't working on the ground fun.

Had the shop mechanic actually installed a genuine Toyota pipe/muffler, I may have considered the cost reasonable. But, wowzer, I was feeling rather burned by these guys. Even as poor as my health was, at that time, I should have just done the muffler replacement myself and been done in less than half an hour.
After some exchanges, the shop owner did eventually give me a full refund but, after this incident, my wife never took her car back to them, either.
One lesson for me: do repairs on my Tercel myself, unless I absolutely, positively am unable to do so.
