Rusted out muffler? (1 Viewer)

[CruisinNoob]

I've got a '99 Land Cruiser that is by no means in mint condition, but it runs well enough and is a reliable winter vehicle. Lately it's been running rather loud. It's been throwing a cat code for a few years but otherwise been fine. Recently it started having misfires so got new plugs, a new coil, and new fuel injectors. No more misfire codes and it seems back to snuff, but loud still and doesn't always start immediately. Cat code still comes on sometimes but usually stays off if I reset it. Had the transmission looked into but it came back clean.

Was chatting with an acquaintance about the value of the car, he asked me about rust so I decided to take a closer look. The body is alright, has a few surface level spots I'm going to sand and touch up, but no rot.

Underneath there's varying levels of rust I need to do something about. And then I noticed an important looking component that's really rusted through by rear passenger side tire.

I think I found the problem. I heard hooves and looked for a zebra, but it was a horse...

This is my muffler, isn't it?

It used to be...

 

[CruisinNoob]

Do I need to weld the new one in? Or can I just bolt it in place?

 

[CruisinNoob]

False alarm, it's just the paint.

Another rusted out component, and a previous owner surprise, there's a heart drawn on it.

 

[CruisinNoob]

Not sure I like the looks of this wiring, either.

Noobie searched and noobie found. New muffler... - https://forum.ih8mud.com/threads/new-muffler.1249442/

Guess it's back to rock auto for a new muffler.

Check www.partsouq.com, enter your VIN and you should be able to find the muffler you need. Provided it is still available, I would spend the money on a new OEM muffler versus an aftermarket. I picked up one last year and it bolted right in. Just my $0.02.

I wouldn't worry about the wire loom, unless the actual insulation is cracked. You can replace the split loom or wrap it. It's just there to protect the wire insulation from abrasion.

The actual wires are looking a little brittle, I have to take a closer look and make sure they're not bare.

More Information for WALKER KIT2787358

I was thinking of picking up this walker kit and just replacing the whole back end so I didn't have to deal with having to seal two rusty ends to the new muffler. The new oem one (1998-2007 Toyota Land Cruiser Pipe Sub Assembly Exhau 17403-50151 | Toyota Parts Center - https://parts.olathetoyota.com/oem-parts/toyota-pipe-sub-assembly-exhau-1740350151?c=Zz1leGhhdXN0LXN5c3RlbSZzPWV4aGF1c3QtY29tcG9uZW50cyZsPTkmbj1Bc3NlbWJsaWVzIFBhZ2UmYT10b3lvdGEmbz1sYW5kLWNydWlzZXImeT0xOTk5JnQ9YmFzZSZlPTQtN2wtdjgtZ2Fz) costs quite a bit more and the walker one is stainless and cheaper. Not sure if it will have good longevity, though.

The oem from parsouq is a bit cheaper than the other listing I had. Good find. I've seen good and bad comments about the walker muffler so now I'm wondering if not having to deal with the rusty resonance pipe connection is worth a shorter lived muffler.

I'd have a good look at the rest of the exhaust system before ordering just a muffler.

I'll give it a better look when I get time to crawl back under. I put some rust reformer on the underside last night to try to delay the inevitable. Found a spot of rot under rear driver mudflap. So much for my unrotted body.

I'm hoping to continue putting off replacing the catalytic converters indefinitely. A can of cat clean usually goes in and the codes reset and she's golden. The whole exhaust is covered in rust including them and they didn't get any rustoleum since I was told not to paint any exhaust components for safety reasons.

I just put new tires, plugs, a new coil pack, new fuel injectors, new washer hoses, new fuel filter, new oil and filter, plus tools and other odds and ends needed to complete the jobs so may just go with the walker set and let future me worry about going oem. It's getting expensive doing all this maintenance at once so I might just bypass the muffler with a length of pipe and install a new one at a later time.

Would it hurt anything to just leave it like this for a while longer? I know some people remove their mufflers on purpose and while it's currently running loud for my tastes it's far from the most obnoxious rig on the roads around here.

The muffler is going to have to go on the back burner. It's been giving me trouble starting lately so I had the guys at O Reilly's hook it up to their tester and the alternator is going. Again. We had it replaced a few years ago but I guess the guy did a bad job or used a crappy part. Dang, I really want to believe Toyotas last forever but it seems like my truck is having all these problems at once.

Mine is a '99 with 225k

Cat code still comes on sometimes but usually stays off if I reset it.

While I can understand the frustration, it seems kinda harsh, for a 23 year old vehicle, with 225k miles, that appears to live (or lived) in the "rust belt", with some possible "deferred maintenance", and a likely rebuilt alternator, from an unknown source...

Yeah, it's in need of some major TLC and I'm hoping it isn't too little, too late. I'm going to give the battery terminals a good cleaning and if that doesn't help, check the wiring on the alternator.

I think the old alternator failing may be related to it having been run several years with the wrong battery, I think dad just swapped in something that was laying around. When I put the new battery in a few years ago guy at parts shop said the old one was larger and possibly pulled from a piece of farm equipment. It did last like 5 years, but the wiring and electronics may not be happy about it...

Resetting the cat code is pretty standard for these trucks from what I've read in these forums. It doesn't smell at all and gets cat clean which seems to keep it away for a while. If cat goes bad I think I'd get symptoms and not just a P0430?

0455 could be gas cap or vacuum line somewhere (though I'd do a search on here). P0430 (and it's twin 0420) are pretty common, there are a few big threads on them - looks like you read them. I had 0420 and 30 and put O2 sensor spacers on and it works - still passes emissions (but I don't think VA does a sniffer test, just checks for CELs). Beyond that start small and work your way up. Don't throw cats at it unless it's the last resort. Good luck

This truck is a neglected hand me down salvage title due to some body damage it got in the past, so maybe I started trying to fix it up too late. It has outlived many Chevy's, Fords, and others, but the more I learn about it as I do research to try to fix it, the more I want to hold onto it and keep it running instead of trading it in. I'm just not sure where the line is for lost cause. I don't know if previous owner(s) were nice to it but it hasn't been on a strict maintenance schedule since coming into my family's possession so some of the fluids may very well be oem.

I don't think a new muffler and alternator are asking too much for a Toyota, even as old as this one, but I'm not sure if it'll keep holding up since it has been neglected.
