Your system must be quite old? I think the gemini has been revised now and the Y pipe pieces don't have a flexi joint anymore. You might struggle to find a replacement because I don't think you can buy individual pieces separately and you can't use a normal aftermarket Y pipe (like stillen) because it's a true dual. Maybe you could get them cut out and a straight bit of pipe welded in?

Veilside V3 maybe? https://www.carbon-addiction.com/index.php/product/nissan-350z-veilside-v3-style-carbon-rear-spoiler/

Sure I'll have a look for it when I get a chance, although I've just moved house so god knows where it is

I've had them fitted about a year now and they went through an MOT absolutely fine in April. Can't remember the figures, @Adrian@TORQEN can probably give you more info on the cats themselves.

Fingers crossed! but if not then at least that's the perfect excuse for an Uprev

Hmm tricky, really unfortunate situation to be in. @cob1980 I totally feel for you, with any high end parts I'd also expect them to fit without any issues. Buying parts in advance because they're on sale is something I've done in the past too but storing them past the warranty expiry date is the risk you take I guess. It sounds like Adrian has done as much to help you as he can and the ball is out of his court now, hopefully Ark will sort this out for you as a gesture of good will but due to the fact they're now used I doubt it. I totally understand where you're coming from in the fact they've only been on for 30 mins and your mechanic thought they'd be alright but if there were fitment issues ideally you should have taken photos, refitted the old cats and contacted Ark. Sure this is a ballache because you've wasted your time, but from Ark's perspective now they only have your word to prove they've only been on the car for 1 day not 14 months. If they decide not to do anything about it I guess your options are to cut & re-weld them so they fit properly or sell them on and buy some alternate ones.

Gotta be worth a go grinding the heatshields off to see if that cures your issue. If it doesn't then sounds like the perfect opportunity to upgrade to some high flow cats I've got torqen ones (£419) and can't fault them.

Change out the headunit for one from this century?

If you're replacing the entire exhaust system (except headers) with aftermarket parts but only want a 25% increase in noise/no drone you might struggle, most will be significantly louder. If you're going FI then I wouldn't bother with HFCs (that will ultimately fail), I'd save up for some decent test pipes (resonated ones to kill the drone) and just find a "friendly" MOT tester. In terms of cat back systems I'd probably look into the miltek, it's known to be only slightly louder than oem with standard cats (more so with decats) but a much nicer tone.

You trying to start arguments coming on here and asking a question like that? Like Daisyduke has said, that's a massive question and you need to be a bit more specific on your requirements. Mainly what's your budget and how do you want it to sound? I went for the invidia gemini because it fits all my needs plus it's tried and tested by loads of guys on here so knew the quality, fitment etc would be spot on.

Do both fans work on both speeds when you apply 12v directly to them?

Now managed to source the fluid caps from Tarmacsportz, still after a dipstick cover

What a beautiful example GLWTS!

Nope won't fit unfortunately. There is one in the 370z parts for sale section though..

If you disconnect your battery your alarm won't work? Which if your car does get stolen I bet your insurance company wouldn't be happy about. Also what's to stop them from just popping the bonnet and putting the lead back on? If you're going to do it (I wouldn't) then at least remove the negative lead completely.

I use a CTEK MXS 5.0 and can't fault it

Cheers for the reccomendation @cob1980. After 12 years my zeds original battery finally gave up the other day, replaced it with one of these and like you say it fits perfectly My OCD wouldn't have been happy with the S5 if it doesn't fit in the tray properly

I'm finding this thread really interesting, loving all the work you're doing to the car straight away. It is making me want a mini to scratch that supercharger itch though, I'd love to supercharge the Zed but something tells me that'd be considerably more expensive

At the moment my zed is still on its OEM clutch /flywheel but I've got one of these stage 1 kits ready to go on later this year- https://www.tarmacsportz.co.uk/clutch-and-drivetrain/xtreme-clutch-nissan-350z-z33-vq35de-engine-clutches.html I know Xtreme are really popular and well rated, not sure about the 2 options you've linked. At a guess I'd say the flywheels are pretty similar but the clutch in the JWT kit is uprated hense why its more expensive. I'm sure @buster or @Tarmac@TarmacSportz will be able to give you more info. Also might be worth having a look on Torqen's site or speaking to @Adrian@TORQEN

Maybe they put a cheap nasty one in before like you say then, but yeah you won't go far wrong with exedy/luk. Single mass flywheels do increase performance (they're far lighter which allows the car to rev much more freely), they also tend to be cheaper and last much longer than a dual mass. The main trade off for all this is increased NVH (usually in the form of gearbox "chatter" at idle). On the other hand dual masses tend to be more expensive and wear out quickly (it's usually recommended you change it everytime you change the clutch) but they're far quiter. So really it all comes down to whether you could tolerate a bit of extra noise for the increased performance or not. Also most of the clutches in aftermarket kits are uprated, so they can handle more power and abuse but will make the pedal a bit harder, so it's worth thinking about whether this would be a benefit or hindrance to you.

That's what the cars came out the factory with so if you're after something comfortable for daily driving that'll do the job well. I take it you've looked into/aren't interested in any single mass flywheel options?

I agree everyone's gotta start somewhere, but you shouldn't be adjusting things on the car if you have no idea what you're doing, that could end badly. You should either research beforehand (pretty sure you can find anything worth knowing about Z's on here) or ask/take it to someone who knows what they're doing

Jheez this thread is worrying if it's for real In the future if anyone tells you to copperslip your discs to stop brake squeal please DON'T DO IT

It looks/sounds very clean but I agree with the guys that it's overpriced. Don't let the window issue put you off, that can probably just be fixed by resetting the motor. Also the headlights on every 350z are likely to be cloudy by now unless they've been restored (which is cheap & easy to do). Given that the wheels could do with a refurb to be perfect I'd say it's worth around 8k.

You're right it's not absolutely necessary but it's advisable, to save having to mess around with it again a few months down the line like you're now finding out
