pedro1956 Posted March 5, 2013 Share Posted March 5, 2013 Just ordered my very first Lexus today, having come from owning performance Audi and BMWs I decided on a new Flame Blue ISF. There were none in stock in Australia in my preferred colour so I had to place a custom built order. Apparently the blue version is not that popular so there are minimal stocks which I thought was strange as most brochures and advertising use a blue model. Power was a little down on what I expected so I have ordered the local lexus fitted performance mods. These mods include a port and polish, new air intake and exhaust system with a claimed increase of 52kW without voiding the factory warranty. Has anyone had any experience, good or bad, of this kit?

Ezo Posted March 5, 2013 Share Posted March 5, 2013 I wouldn't have thought it included a port and polish, perhaps just exhaust and intake? How good it is and whether you like it will depend on the exhaust used and your tolerance for drone. Perhaps some more knowledgeable people can chime in for with more info. EDIT: Just realised it's a port match. Rolleyboy has had this done so can probably provide more info.

pedro1956 Posted March 5, 2013 Author Share Posted March 5, 2013 Lexus of Brisbane in the valley. Would value your comments on the mods, considering a $5K price tag are the changes noticeable or worthwhile? Does the exhaust note change and become a continual drone as mentioned above?

RecursiveLoop Posted March 5, 2013 Share Posted March 5, 2013 Firstly, congratulations on your purchase, and I am sure you will be a happy Lexus customer. A well-maintained ISF will give you many years of reliable, stress-free motoring coupled with Lexus' great customer service. This is the first Lexus I've owned, and I'm very impressed with their product and service. I don't know about the JoeZ, but my Borla catback got less drony after about 500kms as the carbon built up in the pipes. If you cannot stand the drone, someone from the US eliminated the drone on his JoeZ by putting back the stock mufflers, but doing so reduces the power gains made from the exhaust. I reckon a swappable system is the best, allowing you to put the stock mufflers on when you need it to be quiet and for long trips, but put the JoeZ mufflers back for a track day or a mountain run. I'm in the process of getting my exhaust guy to fabricate something like this for me: Someone in US first did it and he said it eliminates drone from his JoeZ setup completely. I bought my car off the sales manager at Maroochydore who had already done the port matching on the vehicle. A good exhaust, the HPS silicon tube, AFE dry filter and PPE headers and I reckon the car will be significantly quicker. Also, think about the tyres. The tyres from the factory are quite narrow (225mm front, 255mm rear), you'll probably get more grip with fatter tyres. After that, I think that's about it before you start to really get into warranty-questioning territory by using nitrous or even forced induction (which no one has successfully done in a stable manner). I would also invest in learning the drive the car. I've gotten a good 10 seconds off my lap times by proper driving techniques and learning how the car handles at the limit. A stock ISF will already outrun most cars on the road, with a good driver behind the wheel it becomes an awesome track weapon. Quote Link to comment Share on other sites More sharing options...
pedro1956 Posted March 6, 2013 Author Share Posted March 6, 2013 thank you for your comments. I would really like to listen to an exhaust system before I do this mod. Are there any forum members north of Brisbane or Sunshine Coast that I can contact? Quote Link to comment Share on other sites More sharing options...
Blacky Posted March 6, 2013 Share Posted March 6, 2013 Just make sure you get to keep the original exhaust. This way if you don't like the sound or you sell in the future, you always have the option to return to stock. Same goes for everything, except the match port job. No one can see this anyhow. 1 Quote Link to comment Share on other sites More sharing options...
Ezo Posted March 6, 2013 Share Posted March 6, 2013 I read that keeping the rear mufflers to eliminate droning from the JoeZ leaves the car with no power benefit. Would it be worth doing headers only in this case? That is if you don't want to have to swap them for different purposes. It seems the full Borla fairs better on drone than JoeZ - despite JoeZ himself fiercely defending his product with happy customer testimonials - fair enough too.

Brisman Posted March 6, 2013 Share Posted March 6, 2013 Come down on Sat, we have a Borla, ISS, Joe Z and stock ISF showing up, should be good. I have the package you mentioned in your OP, see you there. Quote Link to comment Share on other sites More sharing options...
pedro1956 Posted March 6, 2013 Author Share Posted March 6, 2013 I will try but sadly I won't be driving my ISF, it does not arrive until the middle of June. There were no Flame Blue versions in the country so have had to order one from the factory :-( I will be in a Sprint Blue Audi B8 S4 instead.

marth06 Posted April 4, 2013 Share Posted April 4, 2013 I fitted a Borla axle back. Good sound, no drone. I also changed intake to Joez intake and Toms air filter. no real power increase, just a bit more responsive, but sounds great, deep v8 sound without the full on ear drum piercing sound.

BULLIT Posted July 1, 2013 Share Posted July 1, 2013 Your getting headers, did you also order the JoeZ? Who's doing the install and what brand of headers did you go with? Quote Link to comment Share on other sites More sharing options...
RecursiveLoop Posted July 1, 2013 Share Posted July 1, 2013 Are you getting the headers installed by Lexus? When I asked them about it, the service manager said he didn't think the headers would fit our right hand drive cars (although the PPE ones I got are explicitly for right hand drive cars).

BULLIT Posted July 1, 2013 Share Posted July 1, 2013 Elgin I would be keen to catch up once you have headers installed. Your car is going to sound like a beast. Have you seen this clip with lots of different exhaust/header set ups. 1 Quote Link to comment Share on other sites More sharing options...
