Its worth paying the extra for genuine floor mats. Not only will they fit the car perfectly, but the carpet is of good quality so they will wear well and will compliment the vehicle rather than stand out like a cheap aftermarket floor mat. https://www.ebay.com.au/itm/LEXUS-FLOOR-MATS-IS250-IS350-IS300H-BLACK-CARPET-FROM-APRIL-2013-NEW-GENUINE/281347390313?fits=Model%3AIS|Make%3ALexus&epid=1343611776&hash=item41819c7b69:g:5JQAAOSw0hlZLM~z

Luckily the replacement motors are cheap: https://bestmufflers.com/bshop/index.php?id_product=5166&id_product_attribute=0&rewrite=xforce-varex-universal-sports-mufflers-replacement-motor-unit-vk03-&controller=product At $50-60 a pop, i dont mind having to replace a motor every few years. There's only a few bolts holding them on.

So the previous owner has removed a perfectly good OEM xenon kit, and fitted some rubbish ebay LED's? My god some people are idiots.

Hopefully a new electric motor will get it up and running again BLK ISF. The workings of the valve is pretty simple, so unless the butterfly valve is damaged (or the shaft is bent/broken) then i cant see what else could go wrong apart from the motor. I took advantage of the Sparesbox.com.au sale last night and bought the Varex Smart box unit (saved $100 with the sale). The sale finished last night so it was now or never.

If the previous owner has played around with the lights (and done a shocking job of it by the sounds of it) then its likely the car did not come with xenon lights from the factory (because if it did, you would not replace the xenons with sub quality LED's unless he was an idiot). You will need to post up a few photos showing the plug and general area at the back of the headlights for us to give more info, but it sounds like you will need to buy 2x new headlight bulbs (consult the owners manual to see what style of bulb is required). If you want to fit xenons, then i would recommend purchasing a set of good quality aftermarket xenons (includes bulbs, ballasts and wiring) from a company such as Morimoto or Phillips.

Also see here as a similar question to yours was asked a few years ago.

Here are a couple of options that should be closer to you. Lexus of Chatswood certainly does get a good wrap by people on here, but you are always going to be paying much higher prices at a dealership than you would with an independent mechanic - and in my experience, the work done by the independent mechanic is of a higher standard. https://hitechautosydney.com.au/lexus-mechanical-repairs-electrical-services/ http://www.omegaautomotive.com.au/lexus-service/ The good thing about IS250 and IS350 (and even the ISF) is that they are easy to work on, an do not require any special tools for general maintenance and servicing like most European cars. They also do not require any fancy spec of engine oil, so just a decent quality semi-synthetic of full synthetic 10w-30 oil is all it needs.

Good to hear you got yours sorted BLK ISF - that must have been a bit annoying, but good to hear xforce kept supplying motors and eventually replaced the muffler for you. For now, i just purchased the remote control setup with the wiring harness for the twin mufflers. If i like the sound of the mufflers then i will probably buy the bluetooth smart box as this gives a much greater level of control over the volume and how the mufflers operate (i thought it was a gimmick at first but ive seen a few videos and its actually quite a good idea). With the remote control setup, i was surprised to see that no matter how briefly you press the open/close button on the remote, the valve on the muffler moves its full rotation (completely open / completely closed). I figured it would not move as quickly as that and would allow you to have the valve part-open, but this is not the case. At least with the bluetooth smart box, you can select exactly how much you want the valve to be open, part throttle/full throttle operation, as well as that drone eliminator function, and the GPS function to close the valves as you enter your street is also handy.

Updating this thread in case someone else finds themselves in the same situation. I've had some custom rear mufflers (Dimensions: 10x4x14") fitted to my IS-F for around 5 months now - and although they did reduce the overall sound a bit (perhaps 15%) over the xforce mufflers that i previously had fitted (Dimensions: 8x5x13"), i still want to be able to shut the car up even further sometimes if its late at night, or if im giving a family member a lift, or if im just not wanting to hear the exhaust as much on a particular day. So after looking at Reaper, Adrenalin, Magnaflow, etc etc mufflers, as well as other mufflers Xforce offer, i decided to go with some Xforce Varex mufflers (which in hindsight i probably should have just done the first time around instead of getting the custom mufflers). I went with the VMK40-250 mufflers which are a larger bodied 10x6x15" muffler - so even when the valve is open these mufflers should be quieter than what i have now. And with the valve closed, i should be able to give a work colleague or a family member a lift without being embarrassed about how loud the exhaust is. I was a little concerned that these new Xforce mufflers would not physically fit under the car, given that they are quite a large body and also because the Varex motor is mounted on the side of the muffler (making it even wider), but on the weekend i removed the current mufflers and mock fitted the new Xforce mufflers and yes they will fit nicely in there - the only issue is that some of the pipework leading from the diff to the mufflers will need to be extended and the flanges need to be cut off and re welded. So ill get these new mufflers installed in the next few weeks and will update on how the look and sound. http://www.xforce.com.au/xforce-products/varex-for-a-with-a-varex-universal-oval-6-inchx10-inch-15-inch-body-length-25-inch-flanged-inlet-25-inch-single-wall-outlet-side-mounted-motor/productnr-VMK40-250/cid-/vid-

Babalouie you are famous: http://www.vwwatercooled.com.au/forums/f228/lexus-isf-v8-build-125526.html

Hi - you could try Lexmania in Sydney who dismantles and wrecks Lexus vehicles. https://www.facebook.com/LexmaniaAU/

Cool - certainly a rare car in Aust. Love how feature packed these Jap cars are - its fully loaded.

I think its even more of an improvement over stock considering you had the older style steering wheel to begin with (missing the blue leather at the bottom and the silver inserts around the control buttons either side). Personally i think the updated MY11+ steering wheel looks much nicer (more modern, more sporty and more at home in the ISF) than the older style wheel. Aftermarket wheel certainly does look nice, but as careful as i am i know i would scratch that carbon finish with keys/zipper/belt buckle etc when getting in our out of the car...it would only be a matter of time. The black carbon on the new wheel clashes (in my opinion) with the silver carbon on the centre console so do you have any plans to do something with the silver carbon?

Otherwise just buy this and pay it off over a few months: https://www.prospeedracing.com.au/products/invidia-lexus-is250-is350-13-diff-back-exhaust-stainless-ss-rolled-tips.html Or this (not as good quality as the Invidia but you do get a full exhaust system for the same money): https://www.carmodsaustralia.com.au/twin-2.5-stainless-steel-cat-back-exhaust-system

That sounds very expensive for what is a very simple job that would take them a very short time to do. My suggestion would be to use good quality mufflers like Magnaflow. A good size will be 9x5 inch body size but where you need to be careful is the length of the muffler as the Lexus can only accommodate around a 13-14inch long muffler (and some mufflers are longer than this and wont fit). It might be a wise idea to jump under the back of your car with a tape measure and just see what size your current mufflers are, then try to find something in a similar dimension but with a straight through design.

Not a IS350, but when i was looking for my ISF i looked at one which had its rear mufflers removed (muffler delete). It sounded good but was very loud and droney and not certainly something i wanted to have as my daily car. I can only assume it would be much the same with the IS350. Options are (if you do not want to buy a replacement cat back sports exhaust) to have the mid resonator removed or have the rear mufflers removed and replaced with high flowing mufflers. 1) Resonator removal is quite cheap (should be under $200) and will give the car exhaust sound more volume 2) Removal of stock rear mufflers and fitting aftermarket high flowing mufflers (around $300-600 depending on whether you get good quality mufflers or cheap ones and the tips you choose) and will give the exhaust both more volume and a deeper tone.

Just get Nulon or Penrite coolant from Supercheap/Repco. Not sure if these 1UZ's use green or pink/red coolant - but you can get either type readily these days. You should be able to easily find the coolant capacity either in your user manual or googling.

My ISF does the same thing - if the window is down partially and i hit a bump the window rattles.

I have had good experience with Remsa and the Bremtec Euroline pads so i wouldnt have any problem recommending either of those brands. I currently have the Bremtec's fitted to my ISF as well as my wifes Audi.

https://www.wavesdetailpro.com.au/pricing/ looks like they use good quality products and polishing machines. Otherwise if you go to Sydney you will have more to choose from but also no doubt you will pay more too: https://www.carcareproducts.com.au/ https://definitivecardetailing.com/

A bit of an anti-climax....rocked up at the dyno this morning and they tell me the computer is not working so we cannot dyno the car until a new computer is sourced and hooked up.

$40 just want it gone.

Ok thanks for that - good to see. That's a really nice increase for quite a basic (and relatively cheap) mod. As for mods, i've got: - RR Racing tune, - AFE panel filter and HPS silicone intake tube, - Manifold primary cats gutted and manifold flanges opened to 2.5" - 200 cel hi-flow cats welded into the xforce front pipes - Xforce exhaust with custom rear mufflers to make it a bit quieter. Im hoping for around 275kw this time as my last dyno run made 265kw witht he RR tune, intake mods and the xforce exhaust. So the changes ive made for this time are the manifold flanges, the hi flow cats and the custom rear mufflers.

Yes i have seen that thread previously and that's where i got the idea to open the flanges up on the manifolds. So i guess im hoping for a similar result (approx 10kw) but im hoping its not all just top end...it would be nice to get some more low/mid range out of this engine as its a bit lazy under 4,000rpm.

Nice one - good price for 6L.
