Hi People,

I have a fresh mystery at hand (without solving that other one about a disconnected hose in engine bay).

Yesterday when driving home, I noticed a squeaking noise (sort of like the springs of on old bed) coming from the rear left of the car every time I would turn. When walking away, I saw a dettached cable coming out from underneath the back of my car (R34 gtt). It seems to be a steel cable wrapped in what looks like a thermal/heat-proof material. The end seems to have some threading (suggesting that it may screw in somewhere, or something screws onto it). But I can't seem to see anything except a few holes in the underbody (nothing with threading) where it may attached to.

The first pic shows what it basically looks like. The second pic shows where it is attached (on the back left, inside the "support" for the rear bumper i guess). There isn't one on the other side (the place where it would go is plugged by a piece of rubber).

It's on the side of the exhaust...So I'm thining it might be a cable to support the exhaust? But I've never seen a exhaust supported by a cable.

-Is it possible the exhaust was making the squeaking noise when the car was turning?

-Is this cable to support something to do with the suspension etc? if so, why would it be attached to the the inside of the bumper support?

-Is it some sort of grounding wire?

The next time someone looks under their R34, please let me know what this is and what it connects to? Or if you want to be an absolute legend, take a pic on your phone :)

Its for the genuine exhaust. Low throttle one of the exhausts close/restrict, but once you start getting the revs up it opens up. It mentions it on the R33 factory manual - the r34 factory manual does not mention it..... *someone please correct me if I'm wrong.*

hi, yep i thought that too when i looked at it. although on the 33 its closer to the front of the car, but I do think that imho that is what it is. obviously the exhaust is not stock. and they didnt incorporate this.

My GTT has a big stainless steel bracket for the aftermarket muffler in the same spot. nothing else

it wouldnt be a handbrake thats not even close to it.

to test , with cool tailpipe, lay on the ground and wiggle the muffler, 90% sure its a broken off bracket on it. and it would squeak like a old truck on corners/take off. bumps etc.

unless its something added by the aliens ????

Hey all, thank you sooo much for your replies. This morning I was like "damn zero replies"...and now it's like "ch-ching! jackpot".

The fact that a few of you don't have it, puts my mind at ease...since it's not an absolutely necessary thing. Just out of curiosity..those of you who don't have it...do you have stock or aftermarket exhausts?

Since iseekool mentioned it's for the geuine/stock exhausts...mine's aftermarket, yet the cable is there. But I'm guessing it WAS getting used, since the dettached cable and squeaking happened at the same time. unless it's a coincidence?

I'll start looking more closely around the exhaust area, and see if I have any luck. If I can't attach it normally, I guess I could make some sort of metal harness for the exhaust to sit in (as long as that squeaking stops).

PS: i seekool...is that anything to do with the SPORT/SILENT exhaust switch? Whenever i press it, I can hear something moving...but don't notice anything sound-wise...I guess coz it was meant for the standard exhaust.

Once again, Thank you all veryy veryy veryy much :(

I just recently changed my exhaust and there was no such contraption on the stocker.

Kaching! Lol!

My bet would be that if you looked under the car at that thing while a mate pressed the exhaust switch it might move :blink:

It kinda looks similar to an actuator of sorts. And if it was for the factory muffler then it would open/close something inside.

My guess is, it is your Exhaust Temperature Sensor.

If you had a look, there should be a EXH Temp Warning embroidered on your sun visor on the driver side, in Japanese (That's probably why you didn't read it LOL!)

Again that's for the R32, on the R34 maybe different...

I know R32's had them and mine has been cut off, just a cable hanging cuz of my aftermarket exhaust when it came with the car.

But R32's had it near the Cat converter... That's why I can only guess for the R34.

Exhaust Temp Sensor is there to warn you, when the exhaust gets really hot, the temp light will come on.

How does an exhaust get hot? When the engine is running, giving it a good spirited run down the track, but were talking excessively high temps.

That's my guess.

I actually think your referring to a cat temp sensor, rather than an "exhaust temp" sensor.

Every car i have had has it, and its actually there more to tell you that your cat is f**ked/blocked.

Because the cat catches all the nasties, over time it clogs up and causes restrictions. And the restriction will obviously create alot more heat than normal because your forcing the same amount of exhaust through a more restricted area.

If the cat is in good working order, or not there at all (decat), you shouldnt ever see the temp light on the dash come on at all, even on the track.

Oh i see. Thanks guys. Eiher way...whether it's some sort of cable for pulling (silent/sports mode) for the standard exhaust....or a cat temp sensor as you have mentioned....I guess I should leave it on (as opposed to cutting it off) just incase I ever have to put the standard exhaust back on. But yeh, for now I've just just used a cable tie to hold it up and away from the road. Still don't kow what that squeaking is. maybe something wrong with the suspension. I don't know. Oh well. But I guess the cable mystery is over.... Now i'll have to try and solve that other thread I have....about the mysterious unconnected hose in the engine bay. Thanks for everything people. Very very appreciated =)

I see,

That makes sense, thanks for clearing that up :)

What I said in my post is what I was told, but your answer makes more sense.

Cool!

    • My take on gg2 48mm, 54mm, 58mm, and 62mm compressor map for same size compressor vs gg1 : All gg2 only outflow gg1 above 20 psi. As all g gen 2 surge line at lower left of comp map move to the right, all gg2 sacrifice spool vs same size gg1, surge line move to the right worst for 54mm gg2. So for same size compressor if you want best response, use gg1, if you want max hp at >20psi use gg2 but you will be laggier vs same size gg1. Max compressor efficiency drops to max 75% on all gg2 vs max 76%-80% of same size gg1. Iirc lower efficiency means hotter iat less dense air so lower hp at same operating point of comp map. Also curious why gg2 is mapped to lower max rpm vs same size gg1 (only 48mm size both gg1 gg2 mapped to same rpm) : 54mm gg1 165,000 rpm  vs  gg2 160,000 rpm. 58mm gg1 150,000 rpm vs gg2 140,000rpm. 62mm gg1 145,000 rpm vs gg2 140,000 rpm. If gg2 can safely spin to gg1 rpm then they can flow a bit more than as mapped. Good thing that all gg 2 interchange compressor and turbine housings with same size gg 1. So gg1 owners can buy gg2 chra only if planning to boost >20psi.
    • My stuff is all with Shannon's, granted, I don't really have imports I'm driving on the road, however, I've had multiple cars at the same time with them. Presently we have the Landcruiser on laid up cover, Sarah's Kluger on full cover, and the house insured. About 18 months ago Sarah wrote her Subaru Liberty GTB off, insured with Shannon's, and the payout, and buy back of the wreck was super quick. In 2020 we had the VF Commodore totalled in a major hailstorm. Storm was on the Saturday, I called on the Sunday and lodged it, vehicle was towed on Tuesday night, assessment team called on Wednesday to say it was a total loss and get payout details, money was in the bank on Thursday morning. Have had a few other claims both at fault, and not at fault, over the years, and never had an issue with them.   Funnily enough, they're also the cheapest insurer I find for things like Sarah's Kluger.   I will say I'm less impressed dealing with them lately around "the experience", as a lot of their staff that you deal with aren't car enthusiasts. Shannon's has a much more main stream feel ever since they decided to become "big corporate", laid a heap of staff off, and then hired a bunch of non enthusiasts. At the same time they've been making a push to be less "call us and we'll personally have someone who cares help" to "hey, this computer can do stuff for you" and are trying to get more square pegs to fit round holes. (That's just the vibe I get from them). Again, have had no issues with claims with them, but get a bit of a "less personal" feel from them.
    • A thing I wasn’t happy with with enthusiast was during the initial phone call they told me they’d insure it for 130k but needed photos.   I then sent them photos and they told me $80k as there were other cars either similar modifications available for around that price, I told them to send me the links to said cars so that I can buy them. i then sent the modification list with prices of the parts (no labor) and the price then came to 115k, which is still shy of the 130 that was agreed in the initial phone call 
    • Ask me a bit later this week before payday
    • I agree that delayed payment probably isn't the most suitable solution. It seems a solid complete transaction would be best. As I wouldn't be using this sale as a line of credit that would typically earn interest, we can probably arrange a much cleaner single transaction deal. I can do $92.52 today. Would you prefer EFT, or Cash on Pickup?  😛
