#541 of 874 exhaust extension
Nov 29, 2003 (9:59 pm)
I am considering a 4Runner V8 to replace my Nissan Pathfinder. I have a chrome 'exhaust finisher' on the end of the tailpipe, that is about 3" OD, and has some set screws to position it on the tailpipe. If you have an Infiniti dealer in your vicnity, it is off a QX4, after 2001, with the 3.5 litre engine. Both the Nissan and the Toyota have a straight exhaust out the rear, so it can extend the pipe, perhaps into the slipstream. It sells for about $45 Canadian, and might do the trick. I don't have the part number handy, but it is called an 'exhaust finisher'. Hope it may help!

Guys, i dont understand the need to sell vehicle and for few small problems. despite of sulfur smell and some other minor complaints its a gr8 truck. tourag, pathfinder and any other SUV dont even come close to the rugged looks and offroad capability this vehicle has. Do i feel bad about sulfur smell, yes i do but this is so rare of a problem and i am aware of it b/c i've become too concious about it. Was i dissapointed by Toyota, yes, to some extent. But this problem is fairly eliminated by using better gas. Did'nt u read the post that some oil companies are selling low sulfur content gas. i hav'nt tried those since my pb was sloved just by using SHELL 89 octane.
About that exhaust smell getting in cabin, it is also eliminated by changing it to fresh air with-in minutes.
Do we live in air tight world where no smell can enter our nose. Hav'nt u guys ever breathed in open air ever?.
Have you driven this vehicle for 5-10 k miles?. come on. take it easy...you should have done your study before buying a new vehicle, instead of selling it right away.

First of all, it doesn't matter whether it is recirc, or "fresh" air, so there goes that argument. I also ride a Harley, I sorta understand what outside emissions smell like. Waiting 5-10K miles came 8-13K miles ago for me (18K miles and still stinkin'). And finally, the MOST important point is, changing the gas eliminates the odor, NOT the fact that the vehicle is emitting its own emissions right back in the truck. As far as your suggestion about researching a vehicle, you are right on the money. I researched this thing to death before I bought it, that's why I made the choice. I hope other folks are doing the same thing so they can see that they are potentially throwing money away. I can assure if this discussion group existed at my time of purchase, I would have been much better off.
#544 of 874 > Another Satisfied 4Runner Owner With NO SULPUR ODORS
Nov 30, 2003 (7:52 pm)
This evening I was walking out of the local supermarket when I noticed a person loading groceries into their new 4Runner. I had to ask the questions, How do you like your 4Runner?, What size engine do you have?, What year is it?, When did you buy? and last I asked....ever get a sulfur odor?
>Best truck she ever owned, loved the vehicle.
>It is a 2003 V8 SR5 purchased in May 03.
>And she never has smelled an odor other then the first week when new. She drives with the back window down all the time and never has had a problem.
>She uses Mobil regular.
Her previous vehicle was the 1999 4Runner SR5. Until buying her 03, this 99 was her favorite, she really did not want to let it go.
After all my questions she realized who I was, she teaches with my wife, I was embarrassed that I did not recognize her, I was only doing my informal survey. Her husband has a new Tundra with the 4.7 L., I need to ask him the same questions.
I have now discussed this with four owners of new 4Runners and have driven five different 4Runners. Only one of the four people had some odor when first accelerating hard, then no problems after that. I noticed it on one of the five trucks I test drove, again after hard acceleration with the back window down, Maybe it is a combination of the gas used and how it is driven??
Or maybe 1 in 200 owners have a problem with the smell. ( just a guess!)
Yes I do have some concerns, I pick up my V8 Ltd this week. I will use premium (low sulpur gasoline) when possible and if I have the odor will have the Borla exhaust installed. I am convinced that this is the best mid size SUV and will not consider anything else. If I thought otherwise I would keep my 02 SR5 a few more years.
Interesting note: I was behind a Trailblazer last week and guess what.... it was emitting a sulpur smell much worse than the one 4Runner I had tested. Maybe the sulpur smell is the least of this Trailblazer owners concerns?

Hope your informal survey works to your advantage, I really do.
#546 of 874 Exhaust diversion
Nov 30, 2003 (11:02 pm)
derrickjones, your Midas guys must have been having an off day. I can understand their reluctance to extend the exhaust farther rearward (though the entire exhaust system on the 4Runner is so long that the tip on mine never seems to get very hot) but that seems like a less-than-optimal solution anyway. The air directly behind a blunt-ended vehicle like this one seems like a poor place to dump the exhaust.
I'm surprised that the Midas folks didn't suggest cutting about 5" off the pipe and welding on an elbow (or making a 45-90 deg. kink in the existing tube) to dump the exhaust out the side. That's also a better solution (in terms of ground clearance) than a downward extension. As far as I can tell, this is basically what the Borla systems do. No chance of burning anybody, better ground clearance, and it places the exhaust tip more into moving air and farther from the cabin vent outlets.
As far as the Touareg goes, I'd research that vehicle very carefully. The info I've seen so far places its reliability/durability right there with the rest of the VW line, and that is not very encouraging.
tacoviva, I only partly agree with your conclusions: "...if there was an easy fix, Toyota would've come up with it. As it stands, the only way to fix it is to sell it, or install a $1000 Borla." I think a good diversion to the side would qualify as an easy fix to one part of the problem, and would be the equivalent (for this purpose) of the Borla. It doesn't fix the fundamental problem of frequent smell production, though, and I agree with you there.
If this problem was more prevalent with the V6 instead of the V8 I'd suspect a cause from some of the V6's more recent technologies such as variable valve timing or fuel/air sensors instead of oxygen sensors (I won't bore the group with the explanation; ask if you're interested). But that isn't the case, and nothing I've seen explains why Toyota hasn't diverted the exhaust.
I'd test the diversion myself with plastic pipe. The exhaust tip is just over 2.55" OD and just under 2.5" ID. You could even use a standard sweep elbow from central vacuum tubing (about 2.25" OD at the shoulder), taped on the outside to make it bigger. You can divert the exhaust more than 8" to the side without any danger of contacting or burning anybody, and I think that would get it completely away from the cabin vents.

I'm on the same page with your highlander7. I plan on getting my 4Runner toward the end of April and too will try the low sulfur gas and if that doesn't work have the dual borla exhaust system installed. Let us know if you've had to go the dual borla route.

Incorrectly over-inflated price stated of $1,000 for the dual Borla. Must be buying it at Jack's Mark-up shop or Taco's embellishment center.
You can buy the Borla for $600.
