WHAT HAVE YOU DONE TO YOUR 3RD GEN TUNDRA TODAY?

Awesome, thanks! I will do that just for extra safety. I might even email Holley/Flowmaster and ask them as well.

 

yeah ask them cause who thought that was a great idea to put a big heat source next to a rubber item. biggest concern is if you do stop/go traffic with no air flow to cool that area off.

even then ive seen posts/video even having an exhaust near a hitch carrier setting coolers on fire or melting them pretty easily.

 

Meh.
From personal experience: wife had a 2005 4Runner with Borla dual exhaust for over 15 years.
That exhaust ran as close to the spare tire as yours does.

Nothing ever happened to the spare in those 15 years.

 

I fixed that for ya. Getting lucky and never needing the spare is probably not something I would lean on for 30 bucks worth of materials for insurance. Heat and tires don’t mix.

Did you have to have your truck flashed/remove the air dam?

Was install tough? Been wanting to book that RC winch bumper just a little on the fence about install...yours is the first one I've seen in the wild

 

I thought about putting the spare in the bed once I get my tonneau put on.

No? Bad idea?

Or just remove a 60lb spare entirely and replace it with good luck.

I also bought that exhaust wrap that @TundraTT suggested.

 

Wanna play a Tundras.com scientist for a day for us and perform a semi-scientific test?
(try to control env variables the best you can (same day/time/wind/etc))

Test 1:
Warm up your truck, and keep the RPMs at about 3000. Measure the temp of the tire in a spot closest to the exhaust pipe, then measure the temp of the exhaust pipe itself there.
Test 2:
Wrap your exhaust pipe in heat shield/wrap of choice, then repeat test 1.

I'm genuinely curious @ results.
To someone else above: I don't doubt the impact of heat from the exhaust pipe being this close on rubber of the tire, and don't dispute its damaging effect.
W/o any at all tests and numbers, all we can say is that "yup, if you run your spate tire stationary right next to a 'hot' exhaust pipe it may melt(?) or fail prematurely due to excessive heat.

 

Took it for a 20-minute drive. 69 degrees outside (giggity).

Pics are exhaust, tire, exhaust, tire. I also called Holley tech and they said the exhaust by the tire is too far back to get hot enough to do any damage, but he also sounded bored AF about my question and maybe life in general.

 

...that SOB went and actually did it!

You sir are a scholar and a gentleman.
Cool (or slightly warm) to see some numbers.
Now, add the cooling factor of wind rushing against the pipe/tire and removing generated heat while in motion, and we have what?
Well, nobody knows....but I, for one, would be OK with risking my life with a spare tire mounted that close to the exhaust pipe, based on what you see there.
Will it ever explode once in use due to the extended exposure to heat generated by that exhaust pipe? Who knows....and the potential risk is yours to ponder.

If you choose to run like this, dismount that spare tire say 5-7 years from now. Send it for rubber/spectral/x-ray/etc analisys, and post the results here.
Nobel prize of Tundras.com awaits you! I'm sure!

Thanks lol. What I think is cool is that you can buy this cat-back and basically put in any muffler you want. I almost put a Borla in it but didn’t want to possibly deal with drone again.

Since I already bought the exhaust wrap I’ll plan on just wrapping it. I can try this same test once it gets 90° out.

 

Side note:
Random sources online specify average operating temp of DOT tires anywhere from about 150-200 degrees (some lower, some (racing/etc) higher)

Consider this (and these are only my own musings):
In the average overall lifespan of that spare tire, if the average temp of the spot closest to the exhaust pipe does not exceed 200 degrees, I wonder if the effect isn't actually reversed from the concern at hand. Meaning: the tire spot closest to the exhaust pipe is actually "conditioned" much closer to normal tire operating temp, thus that particular section of the tire may in fact be in better condition as opposed to the rest of the tire.
Over time (years perhaps), the spare tire rubber will dry/etc out, being only subjected to external env changes. The spot by the exhaust pipe stays in "normal operating temp" much more and more frequently than the rest of it. This is assuming that the temp doesn't over too high, as to actually cause real damage to that spot only.
Ironically, the tire may fail not b/c of the "warm exhaust" spot, but anywhere except that particular spot.

We'll never know for sure (I have no clue if any real scientific testing of the sort has ever been performed), and if any thing ever happens, the echo chamber here (anywhere) will simply repeat the "common sense" response of "see, we told you so".....without actually knowing for certain.

I gotta feelin' I should lay off the sake for a bit, don't I?

 

Warm or cold sake?

Yeah who knows, I hope the R&D team over at Flowmaster didn’t overlook a glaringly obvious problem when they designed this dual exhaust. I assume they didn’t?

 

I’m not sure what’s happening but life’s too short so cheers!

 

That’s awesome work sir! I was thinking about the 3-400 degrees from the manifold/downpipe area. Never temp gunned a tailpipe before! That’s surprising results. I apologize if I made you buy a wrap. It’s something I would do for piece of mind anyways.

 

I think its because that tire is so far back. Its only a couple feet from the tailpipe.
I understood what @99ways2die was thinking, which I assume was, “lets get this as hot as possible to see what the temps could be in a worst case scenario”.

But I did a real-life scenario, I thought that even if it was stopped somewhere on a hot day, it wouldn’t be idling at 3k RPMs.

Again, I think the coolest thing is that flowmaster made a dual exhaust for the 3rd gen for under $1k. I say sell the flowmaster and put on any muffler you want. I really like the fact that my exhaust is unique and probably no one else has a dual exhaust and especially a Magnaflow dual exhaust.

 

Finished covering the glossy piano black plastic.

 

links?

 

looks nice! Were you able to take that part of the door panel off, or you just applied it while attached to the door?

 

The name and url gets blocked when I type it. I put a partial name you can google in an earlier post in this thread.

yes,it’s applied directly to the existing plastic. basically a vynil sticker.

 

I’ll take anything that stops the glare reflecting back in my eyes

 

I asked for a coupon for this forum. The seller is offering 10% with coupon save10.

 

honestly I just searched "2022 Tundra Heated Steering Wheel" every morning for about 6 weeks and this was the first listing I ever saw so I bought it.

 

Finally had my CBI covert bumper and winch installed. Also swapped out the mustache trim for color matched.

 

@DoMoToyota What light bar did you put in the grille? Any supports needed? Is that a OE grille or other supplier?

 

OEM grille, diode dynamics light bar and they sell it with a bracket for this application.

 

Installed RC sport fender flares over my SCS F5s to eliminate some poke

 

Well I traded my white 2021 sr5 for a 23 grey sr5

 

Haven’t regretted my switch so far- went from a white 21 SR5 Trail Edition to 22 Black Limited about 15-16 months ago

 

I assume there’s no front spoiler (air dam) interference.
