Muffler replacement options? (3 Viewers)

[gregnash]

I had the shop order me a Magnaflow 12288
Sounds more throaty at idle and low revs. Slightly louder in general, but really unnoticeable. No drone at freeway speeds, but then again the tires (Falken WildPeaks) might be drowning out the muffler

Wished you asked earlier, I was at Moon Rocks two weekends ago.

All good dude and I run the same tires as you. I don't find them to be overly loud so would be nice to hear the truck a little more than anything else. Only time I really hear the muffler/engine is when I really hammer it. This was why I loved my old THRUSH Welded muffler on my FJ60.... gave an ever so slight rumble/grumble at idle and nice throaty sound around town and on the freeway but nothing that was obnoxious or overly loud or the like. Have been debating on if I want to order one and have the local shop install for me. Don't really have the time to do myself at the moment, let alone the space.

This is how mine looks like underneath the chassis.
The way you described the THRUSH muffler is very similar to the Magnaflow 12288, I can barely hear the muffler when WOT, more engine noise than muffler. You'll barely notice it with the windows up.

Other than the fact that the Thrush is like $60 max compared to the $100+ of the Magnaflow but I know people that love them regardless.

I spent 50 bucks and had them just weld a pipe in place and run the resonator only.

What does it sound like?

What does it sound like?

It’s not silent like stock but just sounds like you have a “performance “ exhaust on it. It’s kinda fun but on long drives my wife gets a little annoyed. The muffler shop was actually surprised how it sounded. I like it plus it covers up the small tick in the manifold that we’ve all grown to love.

Noticed my muffler is starting to slightly leak at the seam. Debating between my options. Can just deal with it, maybe try some muffler cement along the seam, or do the right thing and replace with OEM.

Seems like pricing from Partsouq shipped is still less than anywhere in the US. Is this the best option?

This is certainly not a new topic, but I thought I'd share what I learned on my muffler replacement today.

First of all, I bought this muffler from Amazon:

It came with the necessary gaskets for the flanges, as well as the output clamp

I bought these bolts: (you'll need 2 packages for 4 bolts)

Now if you've read any of the other muffler install posts, you'll see absolute nonsense re: soaking bolts in PB Blaster or whatever for a week prior to your uninstall.

Installed mine a few months ago, no difference from OEM imo. Just grind off the internal nib for the mating to output, makes it much easier, Reuse the OEM clamp. Done.

Mike, Just get the Northeastern one referenced above.
My recommendation every time this comes up. It is good quality,fits perfectly, and is silent.

Awesome thanks for sharing that thread, I'll do my homework

Really, even from the UAE? That sucks

Thanks for another vote for that Northeasten option, good to know others are running it with success....

Well I don't know.... For now I've concluded that every single part on this vehicle is OEM ( except rear coils ) so If I am going to replace it I will just save up my doll-hairs and get OEM when possible.....

On the flipside, $9 bucks and a tube of JB weld muffler cement seems to be my current solution..... I know its not glamorous nor is this OEM lol but the leak is very small and is like just a long the seam... Cleaned up the rust, pushed some of this goop along the crack and will let it harden. Worst case, it doesn't work and I'm back where I started, seems worth it for now.

Also thought it was interesting to see " Futaba " stamped on my Toyota muffler. Far as I know Futaba makes transmitters and receivers for the RC world.
