Hey all,

Look for some recommendations for replacing my muffler and tail pipe on my 99 v6 Cali emissions 4Runner.

Living in Maine kills these every two years.

Thanks

I can't think of any way to combat corrosion in a state that uses salt-based de-icing (and has strict inspections). Something other than 409 grade 'stainless' steel might help? I don't know. Seems like a consumable in the salt belt. Prices seem to have gone way up - I was taking a look at the Magnaflow cat-back system I got through a t4r.org group buy a couple years ago and they are $300 over what I paid. Dang.

You'll need something stainless. It wont be cheap.

I don't think high temp paint will work here, otherwise we'd see painted exhaust components from factory

The cheapest solution I have found have been the northern stainless cat back exhaust from Ebay. The are stainless but they will still slowly rust. As lots of grades of stainless steel does rust ( I know that doesn't make sense to me either but those grades do exist)

This is for a 2002 but they have the exhaust for all the 3rd gen years. Will these last forever...No.. They will last mostly 4 years or so as we are testing but they are alot cheaper then walkers and they work plus for the price. They are a good option.

I installed a Walker SS muffler with lifetime warranty and it lasted about (wait for it)....two years. Walker would not deal with me - said I had to work through the retailer. I had purchased from Amazon and they told me to contact Walker. I finally got a warranty replacement from Amazon but they told me that was like a once in a lifetime gift.

So, what do you do? They rust out at the welds. Last time I bought one for a family members Camry, I coated all the welds with high temp engine paint before install. 3-4 coats plus. It seems to be holding up after 2 years but doesn't see many miles. The Toyota mufflers last a very long time but are very expensive. If you go aftermarket and you have a warranty, figure out exactly how you will get it replaced under warranty - you will need it.

My walkers lasted 4 years. I just gave up and searched other options that are cheaper.

The OEM exhaust where high grade semi stainless. They always last the longest but since toyota lifetime warranties them. You have to pay an insane amount for them. So that really isnt an option either anymore. Unless you want to shell out 3 to 4K for the oem exhaust up to the header..:/

This is stainless steel.

I'm thinking about one of these for my 99

That's what I have and it's an idiot-proof install, more so if you can unbolt your OEM exhaust flange bolts easily. It comes with both CA and Federal pipes. So far it looks good after a couple years but hasn't seen a lot of water and no salt. Make sure to tighten any connector bolts downstream of the sensor or you might throw a P420 CEL like I did, but it's an easy fix. The group buy price we got on this forum when it was released made it quite a bit cheaper, but that's water under the bridge. Apparently it was designed by a 3rd Gen guy who works at MF. Made in the USA. Another forum member determined that different grades of stainless were used and opted to have his cerocoated or something similar. Check out his crazy build at that link.

Major plus if made in the USA. Everything I ever tried rotted off...

Anyone tried the Northeastern stainless steel cat back advertised on eBay? Probably made in China but has a limited lifetime warranty and is pretty cheap at $220. Still have the original muffler but it can't last forever, and the OEM from Toyota is close to $800 with all the extras.

A few of us are using it and so far are happy. It’s quiet…..

Yes they are made in China, Sadly they last longer then walkers. I wouldn't be surprised if OEM would be more then $800 now. Granted they would lifetime warranty it.

I run those Northern Stainless.

Why not just go with the Toyota OEM Exhaust, I just replaced mine from the down pipe to the tail pipe with OEM for this reason on both my 1999 4R and 2010 Taco. I didn't realize the OEM 4R muffler came with a rubber damper to eliminate resonation, pretty nice piece. All the parts are still available from Toyota. We use liquid Calcium Chloride for about 7 months up here in the North so aftermarket won't last more than 3-4 years, unless you go with Magnaflow or Borla, both of which are about the same price as OEM with added noise, and not sure they include the downpipe with cat and O2 flange, plus you can actually get the O2 off in a few years using OEM as the studs don't seem to rust like aftermarket.

What's the old saying, buy once cry once.

I just replaced my muffler with a Mangaflow. I am going to wrap the pipe sections of the exhaust line, then coat it with sealant (exhaust specific)

If I wanted to remove the entire system from the exhaust manifold or cat I can only imagine the struggle those bolts would represent

Thank you everyone. I’m hoping to get through the winter with what I have.

I’m not keen on dumping more than 300 into it because I still have to budget for some body rust repairs as well.

Thank you again, and happy New Year!
