Same thing has happened again. This time whilst we were out and about at the cinema. Started the car again to hear the V8….buggers…..Think it’s time to sell and unfortunately another reminder as to why people can’t have nice things anymore.

Reviving this thread as it's relevant. We had our cats taken from an LS600hL recently. You could actually hear the V8 which was nice, although the gearbox let's down the sporty sounds! Lexus say they haven't heard of this car being targeted before it's usually the CT. Beware it's a growing issue. Be careful out there! Also £1800 plus vat plus gaskets for OEM replacement....we went down the sports cat route!

Some pics from the event in 2019.

Hi Fellow F'ers, Sportscars in the Park (linked) is back. Who else is thinking of attending? 752 cars currently registered! 🙂 Ill be bringing the F. Is anyone else from the OC joining? Would be good to meet up. Best, Ian

Wayne, do you have the stock or the RR tuned Intake fitted? Any preferences?

Only one set of magnaflow sports cats currently fitted, but you can have two. They are not fitted in the absolute stock locations, but pretty close and this is with all four sensors fitted. Note two sensors need a small extension and the car has also had the RR racing remap file.

Oddly, the whining noise only happens on rapid acceleration - when the wife is in the passenger or rear seats of the car.😋 It's certainly worth checking with the dealer as mentioned earlier. Good luck and let us know what it was.

That is with a sports cat, new manifold and custom(valved) exhaust from STG to make it quieter......still wakes the neighbors on a cold start! It's loud until it goes in gear! I still need to do a review on that system but its a 'PX3' Tesla style screen. It was easy to install but it has been a pain to get configured properly as my Chinese is minimal. Google lens, translate function helped!

Sorry chaps I PMed the videos instead! AFS light is due to my incompetence and the airbag light is temporary and not related to the install.. apologies for the sound quality. If anyone is near Greater Manchester, in the coming period you are welcome to swing by or we could do with a northern F meet up! VID_20210825_201834.mp4 VID_20210809_192711_02_01.mp4

Dear all, as you have probably guessed this has taken considerably longer than expected but I'm pleased to say I have been reunited with the car and my word what an improvement. Unfortunately it needs to go back when Shane gets more time to work on it (October/November) and after the little lambda sensor issue, it's sounding and smelling much healthier. Vids to follow.

I'll DM you Vaynah

Not sure if it helps but I was experiencing a similar issue (perished seals comming away on the 600). Took mine to the local dealer and was very surprised when they said they could just replace the glass and seal. If I recall correctly was just over £500 to replace, prior to lexus owners club discount! It's so much quieter since and a much newer and thicker seal is in place. Happy to take a snap of the part number used if it helps.

To close the loop on this one, it sold yesterday for just under £22K + fees etc.

Of course, it's a fair point. Does anyone have the time or can make the time to shop around and add their findings here? Worth the effort if some cash can be saved for a good quality, durable and well specified performance product. Once the test results are in and paid for, I'll share progress.
