I'm seriously considering getting my extractors ceramic coated in an effort to lower under bonnet temperatures. Is there anywhere in Sydney that anybody would recommend? And how much did it cost to get done?

I never ended up doing mine but was recommended competition coatings in Guildford by everyone I asked. I got a quote of $180 for the silver lower temp coating, $240 for the black super high temp turbo stuff. That was a couple years ago though so no idea if it's changed. Hi-Octane also sell ceramic coatings but I never ended up getting a quote.

So just for standard extractors the silver lower temp coating will do the job fine yeah? $180 is bloody cheap, is that inside and outside too?

I told the guy over the phone I raced the car and he said the black stuff was completely unnecessary unless your running a high-powered turbo car. It did include cleaning and coating the inside as well. Only reason I didn't end up doing it was I've got 2 turbo manifolds that are supposed to be on the car...a while ago . So I just replaced my exhaust wrap for $25 instead from Just-jap. I've had their phone number and that quote on a post-it note on my desk at work for 2 years now... the ceramic looks so lot better than the wrap.

Sweet I'll give them a call tomorrow and hopefully they'll still quote a same price

About 3 years ago, I had my "Liverpool Exhaust" headers done by "Pro-Coat" at Tumbi Umbi, $360 for silver inside and out then black on top. The black works best when applied as a light top coat. But the OEM O2 sensor now gets too hot and fails when I put my foot down. So I rely on the wideband mounted just before the cat with a cool little gas cooler-sampler from Innovative, I'm going to try on my OEM sensor if there is enough room.

Crap I didn't even think of the the O2 sensor, with the added heat flowing through the pipes, will this cause it to actually fail and send your fuel mixtures out of whack?
Also crawling underneath my car, I noticed my wideband sensor was unplugged, should I be plugging it back in?

I'm in the process of tig welding a set of extractors now to get rid of the terrible factory welding inside the tubes.

Once this is finished i will be sending them to Hi octane to get coated.

Was quotd 200 odd for silver, 230 odd for black. Black was only needed for turbo apps

Don't know if anyone has tried this, but there is a cheaper alternative with ceramic paint coatings. I've used it before on the length of the whole exhaust piping (exc mufflers)...put it down to guy-applying-misunderstanding-instructions. It "works" but did it really add any benefit? Can't say it did...but then again, tropical country...
