So as seen on FB, my 19' Varrstoen's are ready to go back on :yahoo:

 

Gone from Falken FK452 255/35 & 275/35 to Continental Sport Contact 6 in 245/35 & 265/35. Small amount of stretch but to me that's no bad thing with big wheels and sidewalls on the CSC6 look unreal. Very motorsport with a clutter free design and BIG font for make, model and size. 

 

Even at slow speeds straight away the steering felt noticeably lighter and more direct. However compliant over bumps and doesn't tramline like the old 19's did. Hopefully at speeds these Conti's are quieter than the Falkens, which were very old.

 

After the tyre swap out, the wheels were cleaned followed by hand polish and sealant. Applying dressing to brand new tyres, is there a more satisfying feeling? :lol:

Cheers matey, it's was a good session and left at room temperature to cure for 3 days - not intentional as the weather has been rubbish recently to be swapping wheels and spacers over.

 

Kiwami sealant doing its thing and hopefully provides a couple months of protection.

Thank you Ben, the 350z does wear 19's well. In pictures the wheels look bigger than in real life somehow. I remember last year when I first put them on, they looked massive and over the next few days appeared smaller as I got use to the new look.

 

'19's for Show, 18's for Go' ;)

Car booked in for MOT this morning and worst still at a garage I've never had a car tested at before. Old place (of 13 years) earlier in the year chose not to renew their policy for testing - great!!

 

Fresh eyes over ol' girl and she passed without any advisories, I even asked the tester afterwards anything to keep an eye on for next year? Said 'nothing' and joked just tyres and brakes lol

 

After a very proud drive home, with the wife at work and kids at their favourite auntie - I set about treating the her :yahoo:

Ceramic coated and titanium heat wrapped Motordyne ART pipes, XYZ full merge collector with 200 cell Sports Cat. Thank you also to Tarmacsportz for the gasket and bolt kit :thumbs:

Nice work.  Has your car been Mapped, been told when i DeCat it will be needed, i know yours still has cat but just wondered as O2 sensor is before ur Cats now.  Have u had any EML or have the spacers ment you avoided this?

 

Also how did u find the titanium wrap? did you soak it before hand?

Sorry for the Million questions! :lol:

No worries Cal ask away, no not mapped hence the O2 spacers. Been over 2 weeks with a fair amount of driving and no eml as yet, fingers crossed it'll remain so. Yeah soaked the wrapped and damp installed which allows for better fitment and less shards. Heat cycled the ceramic and so far still looks great.

 

Also if anyone was interested, I used 15m of wrap to do the below :thumbs:

Option 18' RAYS decontaminated, protected and put away till winter. Still such a smart looking wheel when cleaned up, strong and super lightweight too.

 

Bilt Hamber Auto Foam 

Gtechniq W60 Iron & Fallout remover

Left to dwell and agitated faces/barrels.

Turtle Wax Hybrid sealant applied wet, rinsed and dried.

Given the discussion over in the other thread I'm curious to see how that single 200 cell cat treats you at your next MOT.

 

I'd always wondered if there was a way of adding another cat for those running HFC's but cant get through emissions. This looks like a great option, though i suspect running this + HFC's would probably not be any better than keep stock cats in terms of restrictions to gas flow.  

 

Then again I think a lot of us partial to expensive wastes of time :lol:

I'm theory if the car is running well and the cat material is of good enough quality, it shouldn't cause concern. Plenty of straight 6 cars have options for a single sports cats ie the below. I'll get the car tested and if whereby it won't pass, il swap out the system to OE spec. Few hours work on the drive once every 12 months is more than worth it for ART pipes.

The biggest problems could be:

 

1. Quality/how rich the content of platinum, rhodium, etc is on the honeycomb substrate.

2. Distance from the exhaust ports. Motordyne have measured header temps around 760 deg C and at the Y pipe intersection down to 450 ish I think it was. This will affect the efficiency because of low temperature, especially at idle when there's low load to heat up the cat to it's most effective temp.

 

 

I wouldn't look at the Japspeed product as something that will pass emissions test - I've seen report of exactly their sports cats being poop on emissions. On the BMW front - that may only replace one of two cat sections. Our own 350Z has 4 cats in total. They're just in 2 removable pipes - one substrate before the bend/lambda sensor and one after. On a R35 GT-R, they will pass a UK MOT with the second set of cats removed entirely, just leaving the first set up near the exhaust manifold. I guess they're high end units and 600 cell+

 

 

I think the benefit of the Motordyne unit is to cut down a bit on the carbon monoxide and the associated smell of it, rather than being effective enough to pass any EPA or UK MOT emissions test. When I bought that unit from the previous owner (also called David!) neither of us realised that it had a cat in it or that Motordyne sold it with the option of one. I would love to hear what yours sounds like with that single 200 cell cat though. Probably almost as loud as mine... :wacko:

Just done a quick google image search on a F30 335i - they have 2 distinct sets of cats - replaceable separately. Just like R35s

 

Be interesting for you to get an emissions test done by a friendly garage that's not going to order you off the road immediately. (like I have done)

^ yeah that's the plan at least to see what's what :thumbs: on the sound front, it sounds just about perfect. Low and deep with somehow a fuller richer sound, oddly less rasp than with the OE cats and JapSpeed y pipe.

4th year of ownership this week and still makes me excited at the thought of driving her, even more so now as I've made it my own from humble beginnings. Still blown away and feel lucky to own such a motor. Often (if it get out the front door early enough) take the long route to work effectively doubling the commute distance, just to drive it more. Definitely one of those cars that begs a turn round when walking away and excitement on approach after a day at work. Ownership remains wonderful and a little treat every time you fire up the big VQ. Its a satisfying feeling the car exceeds my level of skills on the road/track, so speed wise I'm very comfortable with what's under the hood. Thoroughly enjoy maintaining and modifying. Really enjoy the club meets and show gatherings, plus the forum is truly a great place to spend time.

Great photos, car looks stunning. 

 

I'm not brave enough to take any like this as I always wonder what the staff at these places would think of the nutter having a photo session on the forecourt :lol:. That and Tesco's doesn't quite have the same 'style' as the Shell garages ;)

I know what you mean, public places and all that. I took couple sneaky ones before filling up then after paying came out and thought 'thats a picture' the side on one. Bent down to take the picture and the automatic doors opened up. As it was an empty shop I knew without looking behind it was the cashier. Who then said 'nice car pal, I have an 88 bluebird' that he's just restored. Then showed me a picture on his phone and it did look class. 

 

I mentioned to him Caffeine and Machine as he hadn't heard about it, took a few more pictures and went on my way.
