Yeah, only one place that sells the JoeZ exhaust, and they seem to think $840 is okay for shipping. I also got a quote from them, and the exhaust is already expensive enough as it is for $1600, plus the carriage and duty... barmey! The Borla, with all taxes should be about £1050, all in.

Ordered from Vivid Racing, about $1365 inc shipping. Landed, including duty and vat, should be a little over a grand. I believe they sell the Meisterschaft systems also.

Sounds great Stu, very impressed.

Hello all, it's been a while... Made some enquiries and got a pretty good price on a Borla exhaust from the US. Hopefully should be receiving it within the next week or so, so looking forward to that. Borla do a couple of options, one which is axle back, which basically changes the rear boxes only, the other is a full system, which removes the secondary cats and is a dual system. I've gone for the latter I'll keep you posted... Cheers Neil

That just screams dodgy Neil! Lol. ;) Change your profile by the way. ;) Not looking anymore!! Glad you're enjoying it so far mate. Really are cracking motors. Loving mine. :) Cheers. Peter lol, it did occur to me that it might construed that way, but what the hell... ;) Yeah, not good! I've noticed a few lorry drivers busy texting etc On a different note, the previous owner left a note in the service book, describing how much he loved the car and that he hopes it goes to a good home. He also left an email address for the new owner to contact him, which I have done. Very nice chap who had it from new. He's in his late 60's but previously raced bikes and cars; he also tracked the ISF a couple of times a year at Goodwood or Silverstone. He's even offered for me to come down and meet him at Goodwood so he can take me out in his new car. All in all I'm very chuffed that the previous owner is a car enthusiast, as even though it's been tracked, I suspect he respected the car and new how to drive it properly.

The only time I can think of is when I'll be waiting outside somewhere for the wife and daughter. Which reminds me, must stash an emergency DVD in the car

Well I did a 100 mile round trip today, with a mix of motorway and city driving, and I averaged about 27mpg. I'll be interested to see how my work journey is. But any change is probably more down to a happier right foot :) I'm also loving the sound system, but I've not tried a DVD yet (though I'm not sure when I'll actually find a use for it). The satnav is somewhat frustrating, when trying to program it.

I got round to fitting the K&N this weekend, and my word it sounds so much better. I always found the standard intake to sound a little too synthetic, like a symposer. Now it has a hard edge to it, and it doesn't disappear when below 3500rpm. Also noticed that the standard airbox, when flap is open, draws air in from the corner of the engine bay, the same as the K&N, so arguments that the K&N will draw in warm air are totally pointless. Anyway, I'm exceedingly chuffed :)

Yup, a couple One car I have always wanted...one day I will. Must have been a sad day when you let that go. Definitely, though I was using it as my daily, and it was a bit temperamental, so it wasn't ideal. That and I was a wee bit young, so the cost of running it was breaking me a little. It ended up going to America, after similar interest from Australia. Thanks Peter, I'm just starting to enjoy it more now. Before I was a bit overwhelmed with all bloody functions, and programming the nav is still a pita, but I'm beginning to relax and enjoy it a bit more now. Though I wish it didn't have the MPG data, as I'm finding I'm watching that more than anything else! I will be fitting my K&N, that I've had sitting around for 6 months, this weekend. I was intending to get an exhaust, but what with everything going on I'm going to have to put it on the back burner for a while. In the meantime I can do some cheap personalisations, such as tinker with the geometry, maybe change the grille to a body coloured or gunmetal... will have to see. Yup, great minds ay? ;) Were you on MKiv Owners forum? I had mine around 2006/2007. My brother (MrHankyXmaspoo) and friend (JohnnyKnox) were on there too. Our cars below. Mine is the Silver, my bro's the blue, and my friend's the grey

Yup, a couple

Ha, I'm amazed we didn't cross paths then. We left at about 1:30ish Some of my car history highlights include: R33 GTR Vspec Supra TT 6spd Lancia Delta Integrale Evo 2 Gialla 1985 HJ60 Land Cruiser S2000 Integra Type R Civic Type R And I've still got my R32 GTST track car Looks like my work commute is going to be more like 24 mpg. It really doesn't like the slow traffic...

Well, today I finally bought one. I actually didn't think it was going to happen, what with current building work on my house, and the boiler and washing machine also packing up, denting my funds. But a bit of negotiating with Lexus Guildford, and the good wife, I bought this 09 Cadoxton slate, with 40k miles and one previous owner. To say I'm chuffed is a mild understatement Drove back today, the little one fast asleep in the back, effortlessly cruising along, with the poor wife trying to keep up in the Jazz :) I even managed 31.6 mpg average. Will try and take a few more pics at the weekend, and also fit the K&N.

Just get a couple of small, straight through, resonators for the centre, similar to the JoeZ system, one for each side. As they're straight through, they'd be negligible gas disruption. Pete, I had been wondering, did H&S do a 'H-Pipe' or a crossover at anypoint on your system? I couldn't make out from the video...

There's been many a scare, regarding new MOT legislation, over the years, and this is a new one for me. My immediate thoughts are how are they going to know how many cats are on a car from the factory? I don't believe this information is currently being logged; it may be something they put in place for future cars, but I seriously doubt they'd be able to do it retrospectively.

not sure if you read my post well but i dont think i said the C43 lost power infact it made 14bhp over stock but the dude was a bit confused as to why his low to mid performance was compromised slightly after the mods. i guess every car behaves differently after performance parts have been fitted. attached is a before (blue) and after (green) comparison of Joe Z + Intake against Lexus stock intake + exhaust curtosey of clublexus.com concentrating on only the blue and green upper lines we notice from about 2400rpm till about 3500rpm both the blue and green lines are somewhat close to each other through the rpm range with slightly minor gap between them. come 3700 they almost touch but soon after the green line opens the gap between the blue till about 4250rpm where the gap starts to close up again between the two but come around 4600rpm the green line starts to open its gap against the blue all the way till they both fall off at 6600rpm. conclusion from this dyno graph confirms although the intake + exhaust mod (green) did have the upper hand, the stock intake + exhaust (blue) was quite close to it all the way from 2400rpm till about 4600rpm which concludes intake exhaust mod comes alive at the last 2000rpm. which yeilded the dud around 26rwhp. was it a gain over stock yes it was but not a lot to be felt on the road/track once you work it out in terms of power to weight ratio but its still a gain. + the awesome sound which comes with it. Dyno.jpg http://www.clublexus.com/forums/is-f/406273-joez-exhaust-intake-dyno-26-rwhp-19-rwtq-sae-2.html Hi John, sorry my response wasn't aimed at you; apologies if it seemed that way. Thanks for posting this graph, just to highlight to others that a well made exhaust will make gains, over a compromised original equipment, mostly in the higher end of the rev range, where gas flow is at its greatest. This is a 26 rwhp gain, so approximately 33 bhp gain at the flywheel. That is nothing to be sniffed at, and quite definitely 'perceptable'. Plus it rounds it up to a very healthy 450bhp ;) Neil

Yup, should still pass the MOT as the primary cats are still in place. The secondary ones will mostly be there to cover for markets that are particularly strict on emissions, such as Japan and Los Angeles. As far as I'm aware, so please tell me if I'm wrong, there isn't any sensors located after the secondary cats, so no chance of a dash warning light being thrown up.

Yup, afraid so Stu. Link to a picture of a standard exhaust system vs an JoeZ At the very top are the exhaust manifolds with the primary cats attached. Then the downpipes leading to the secondary cats. After that the exhaust joins into a single pipe with the resonator in the middle. Then the exhaust splits again leading to the two giant back boxes.

Hey dude, glad to see you've got a dual setup, though it looks like the secondary cats are still in place, these can be seen on the right hand side of the screen at about 17 seconds. Still, you should see a small gain... As for saying it's going to lose power, that's the most ridiculous thing I've heard. Are you saying this from personal experience or just repeating the ye olde myth 'ooh, you'll lose back pressure and power'? Back pressure is not a good thing, an ideal exhaust would have none. What it does need is to maintain gas velocity, which then, like syphoning, draws exhaust gas out of the cylinder, allowing a greater air/fuel mixture to be burnt on the next cycle. Too large a diameter exhaust, on a normally aspirated engine, will reduce gas velocity and low end power, but we know the ideal size for exhausts these days. For example, a 2L-2.5L engine would ideally want a 2.25inch-2.5inch exhaust. The ISF is a 5L V8, so dual 2.25inch-2.5 inch exhausts are perfect. On a turbocharged car, it is almost a case of the larger diameter the better, as the exhaust wheel on the turbo requires the pressure difference to operate. Neil

On a couple of road tests I took, we used our Isofix base with Maxi Cosi Pebble. It fitted without any problems or issues.

I honestly don't know for sure, but I can't imagine them tooling up for a completely new tail light design.

Sorry, I didn't want to sound like a ***** about it. I admit, there is a big debate, in the US, on whether an induction kit gains anything when fitted to the ISF. However, one universally agreed upon thing, within the ISF community, tuning world, and motorsport, is that fitting a well designed, freer flowing exhaust will see power gains. With the ISF, small gains can be made with the changing just the back boxes alone, to a straight through type. Has anybody seen how complex the internals of the standard boxes are? It's crazy. Even more gains can be seen with a cat back system, and again with further gains from the removal of the secondary cats. After this the exhaust manifolds (headers if you're from the US) can be changed to tubular type which see pretty substantial gains of around 50hp. Now a sizable chunk of this 50 hp will be down to the primary cats being deleted also, something that's probably not worth doing due to MOT and legal reasons, but a lot have had high flow sports cats welded in and seen pretty hefty gains of around 30-40 hp. Realistically, with all this done there are ISF's with around 500hp. There'll be those who don't see the point and expense, that's fine, to each their own. But for me the prospect is exciting, not only for the awesome sound and performance, but also I can't leave things alone and just enjoy tinkering. You could give me an LFA, and I'd want to tweek it. That's who I am. Apologies for being a bit narky :P Neil

I've mentioned a couple of times now; it's not like a Japanese engineer walks into his boss and says "keieisha, I bring great dishonor and shame to our company. We have only been able to extract 417 hp from our engine design. I shall now go and perform seppuku." The manufacturer has a hp figure they want to meet, and especially not to go above, as this is actually detrimental to the program. The ISF is a very quiet car in standard form, particularly the exhaust. To achieve this noise reduction the exhaust gases go through multiple chambers and changes direction drastically, multiple times. This is not good for exhaust gas flow and power. But it doesn't matter as they only want to achieve 417 of our ponies. Same with cost of manufacture of the exhaust system. They can make cuts in cost at the expense of gas flow, again because their hp figures can be achieved whilst doing this. The new RC-F clearly shows that the ISF had been deliberately restricted. What is going to be pretty much the same 5l V8 now has around 470+ bhp. Magic? no... they probably changed the cam profiles a touch, fitted a freer flowing exhaust and cats, and tweeked the ECU.

I give up

Oh, by the way Stu, the more I listen to the outside clip, the more it sounds like a C63, which is perfect :D

Thanks for the offer Pete, fingers crossed I'll get my own soon. Roheel, did you have to obtain adjustable arms/bolts? Sorry, thread hijack
