I have never seen IS250 in UK that had carbon build-up issue, not sure why, but it seems to be only the issue in US. Yes DI in general has flaws (or I should say car with DI only). I have sneak peaked into my engine before and there was some carbon on intake valve stems, not pretty, but nothing tragic. I have done hydrogen clean on my car and it made absolutelly no difference, if anything one of the emission metrics was 0.1% higher. No change in response or how car drives.

So in short, unless you have issues - forget about it! Much more important would be timely oil changes, 10,000 miles is way too long, I would actually recommend 5,000-6,000 change intervals and never exceed 12 months between changes. I can explain in more detail, but that is kind of different topic... but it does help with carbon build-up slightly as well. Other piece of preventative maintenance you can look at would be "catch-cans"... but cleaning carbon in general is not that you would encounter often on these cars in UK.

Hello Linas. I am so glad to hear this information. No wonder I only keep hearing this issue from U.S. YouTubers  and car specialists. After knowing this I won’t be too worried about carbon build-up as long as change my engine oil on time per 5,000-6,000. Thank you for your response. Very helpful. 

Good day everyone. I know carbon build up is one of the main issue for IS 250 so I want to know how to address this problem. Anyone have any experience with it? I haven’t encounter any problem at the moment but just for future preference. I saw a video from YouTube that it can only be fixed with walnut blasters, is this correct? When should we start thinking of cleaning the carbon build up? Thank you for reading. Have a nice day.

I prefer the isF sound. The other one sounds like a pig with wind.

Just saying....🐖🍃🙃

OK . So here's a genuine Hayward Scott sound. I can vouch for it.

 

Hello there. I agree the IS F sound is much better in my own opinion. Very decent sound and very sporty.

My understanding is that currently it is at the discretion of the MOT station. My isf with a Hayward Scott exhaust is a bit loud but the MOT people at the last 3 places ( including Lexus ) said -  no problem it sounds lovely!

They also said that a straight thro' pipe would get an advisory to change it.

But...there is talk of legislation to add Decibel readings to determine a fail or not. We will see.

Apparently they already have dB meters at roadsides somewhere or other but I do not know if a warning or a fine follows.

Hello there. This is very informative. I don’t intend to be loud as that in the video I mean I like it but I don’t want to bother other people.

Just word of caution here - being final model year of the car, your car came with facelifted headlights and tail lights. I understand they may not be to your taste, but they are THE MOST EXPENSIVE lights bar non for this car model (well I guess IS-F rear tail-lights are more rare and expensive). As well being last revision of Xenons in front they are the best in terms of actually lighting-up the road and vision at night. 

So whatever you fit performance and price wise will be a downgrade. I understand you may want something different style and modernise the car and that is fine, just don't throw what you have away. At least £600 for pair of fronts and probably £300 for pair of rears. 

Apart of that you, in terms of quality everything will be downgrade, so I would not worry too much, choose the style you like, make sure they have correct markings (i.e. being certified and legal to use in UK) and that is about it. Vlands are standard option, Vland basically is generic name nowadays for aftermarket lights on Lexus, real Vlands are semi-decent (not as good as what you replacing, but not terrible), but there are loads of horrible quality Vland lookalikes. One other thing to note when ordering - you will need lights without AFS and with DLR, they are slightly different connectors (or internal wiring) and I believe lights for your car will be slightly more expensive. Majority of the lights you will find will be designed for older model trying to imitate face-lift lights you already have, so they have AFS connection but not DLR, I know that DLR compatible aftermarket lights exist, but you need to make sure you get right ones.

For exhaust, the cheapest mod and the one I recommend you to start with - just cur the resonator that comes after Y joint, that will generally make car louder, but should not drone. SS tends to be drone (just properties of the material), seems fine at first but very quickly get's old. If you still not satisfied with sound after cutting the resonator out, then replace rear section of exhaust with smaller silencers, but at this point you may want to put some sort of resonator back, even if it is just straight perforated pipe inside. Generally speaking IS250 does sound nice, but not exceptional, it is V6... it is possible to straight pipe them for maximum effect and they don't sound too horrible, but the question is how antisocial you want to go, or if you want to keep it civil. 

I have already answered your bumper question. 

Good day. Hello Linas. After reading your response it really made me think twice now to modify these lights. Your comments are very useful and informative at the same time. It’s good to hear from someone who have knowledge and experience in this car as of me I don’t have much. For the exhaust yes I will keep that in my mind what you said. I am really hesitant about it because I live in a quite residential area. 

Hello everyone. Looking for suggestions to this small scratch but noticeable in my is 250 bumper grey colour. Any paint correction that is best to apply to this? I attached photos. Thanks very much.

Hello Adones. I can't comment on the exhausts on ebay. Some are good but which depends on what they're made of. Stainless Steel produces a drone but a custom built one can be made not to drone.

Yes fabulous cars and I'm still heartbroken after writing mine off.

I truly understand that. Thank you for your advice. I’m a bit upset today when I checked my car somebody scratch my bumper. I tried to cover it with t-cut paintworks but it’s still noticeable.

On the contrary they’ve been absolutely fine and look great (was dropping a car off at the garage with my brother driving my car) 

Looks good on your black car. I have grey which I think smoke car won’t look fit. My car looks so classy haha. I think red is better

Hi Don I myself have VLAND Headlights and Smoked HC Motion Tail lights providing me with sequential indicators and quite outstanding modern lights. They're on the pricey side but going used or waiting for a deal on eBay is a good shout. 

On your own experience. Is the smoke tail lights not too dark at night?

Welcome to the LOC Adones hoping you find it educational and informative. With regards to headlights/ rear light modifications there isn't a great deal out there but there are a few and you could try custom-made stainless steel exhausts. 

Thank you for the warm welcome. I will check that for sure. Do we have laws to follow regarding using loud or not so-loud exhaust in the UK?

Oh thank you. Yeah I will go for the Vland headlights. I will defo check the Smoked HC MOTION tail lights I haven’t heard of it before. Was it easy to install and no issues?

Hello Adones and welcome to the best Lexus forum there is. Great choice of car you got. What made you want one?

It depends what you call expensive but at around the £500 mark some owners got Vland lights. There are cheaper ones nowadays. Just look on ebay. 

As for exhaust. Just what is it you want in a new exhaust? Tony Banks in Leeds is highly recommended for custom exhausts. In fact he's probably done so many he could make one blindfolded lol.

Thanks a lot for the warm welcome. I was looking for very reliable car that has looks. I want a combination of luxury and sports car.  Oh yeah I see Vland lights online I was just making sure they are good. This is very helpful I might go for this one then. What can you say about the exhaust sold in eBay? Could it be a problem? I will check Tony Banks for sure. 

Hello I’m new here. I just bought a used IS 250 model 2012. I would like to do some modifications for this car. Any suggestions for exhauster and headlights/ taillights that are good quality but not too expensive.? I live in the UK. Also any auto shop in London you recommend that does modifications for this car?
