Chasis Stiffening Plate and Muffler?

[Freedom]

I just ordered my Pri yesterday. So I can't just go out to the driveway and LOOK to get an answer on this.

From the photos, it seems this plate needs to be removed each time you have a muffler change?

On my other cars, I've always gone to Midas for mufflers; and they last me perhaps 2 years and I need a new one.

I saw a few threads about the stiffening plate, who likes it, what it does etc. But I didn't find anything re it's interaction with muffler changes.

Just wondering if anyone has an experience with this?

Why would you require a muffler change every two years?, and any muffler guy should be able to do his work without any problem with the plate installed.

Since the Prius muffler is made of high quality stainless steel, very few have needed to be replaced. Some catalytic converters have failed in early Prii, but that's a separate issue.

Besides, the stiffening plate is just bolted on and can be removed in 5 minutes.

This is a complete non-issue. I'm not sure I've even heard of anyone needing their muffler replaced on the Prius to tell you the truth and certainly not every 2 years.
Anyway, there's a stiffening plate there anyway from Toyota, the replacement stiffening plate is just more rigid. Either would need to be removed and either will come off quite easily.

You had an American car you needed to frequently change the muffler on.
This is a Toyota. My last Toyota was a 1990 Camry, had 290,000km on it and the original mufflers when I sold it last year. Most likely still has the same mufflers today.
Love the stainless steel.

Nope, Honda. Only ever owned a Honda; until now.

I didn't realize this is a replacement; I thought it was a new add on piece. That helps, to know that.

So does that plate have to be done BEFORE putting on the skid plate?

Nope, either order is fine, they don't overlap.

The direct answer to your question is:
Either part (plate or muffler) can be easily removed/replaced independently of each other.

The stiffening plate is not near the muffler and the muffler coupling is 2ft behind the muffler and easily reached.

In fact, both can be removed while you are laying on the ground, no need to raise the car.
Just so you know.

Check, I think Honda must make some cars in the USA?
I just thought I would try and guess.

If you are a bit chubby with short arms like me you might need to jack the car and block it up, just a little to reach the plate or muffler.

I have never needed to replace the muffler on any car I owned. (I only owned 1 before my pri but it was near 100K miles and 8 yrs old)
