That does look the business ^^^ for interests sake, are they equal length? I am assuming that this equal length stuff is due to frequencies of the exhaust. Frequencies of gases flowing through pipes is based on length (from what I remember from engineering) if you have two different lengths with the ends of the pipes next to eachother you might have interference between the two outlets, maybe, which could be bad because... I am not sure...

Besides the weight and space issues (which can be overcome) I think a full twin 2.5"-3" would be fantastic in terms of performance... and sound. Definately something I am interested in and will consider when upgrading my turbos.

blk180 thats the same as mine.

How good is the note!

Yeah it is loud and low but well worth it think.

As far as I know these exhausts are tuned length, otherwise yes the frequencies can disrupt each other if not the same length and power is lost...think about tuned length 6 and V8 extractors, the most expensive are tuned length and give the nest results.

Hey Mat, have u had a chance to get pics of it on ur car yet??

I'm kind of looking into getting one made up at work, but cause of costs and time etc im not 100%

And also because its twin, for tuning purposes where does the wideband sensor sit?

Yeah its a very tight fit.

I previously had 2 x 2.5 into 3, 3inch cat, HKS super dragger catback, which was 3.2 off the back of the cat getting bigger to 3.7 before the rear muffler.

The current exhaust is twin 2.5 all the way through.

What happened between the old & new exhaust in regards to the cat?

Its likely thats where most of your gains came from as there are a few cars even running stock dumps and making over 300rwkw without a drama :cool:

Just gotta get rid of the ole pussy gato!

Yeah you can get the Apexi N1 Dual for 33 GTSt, I know access autoworks had them a while back...

There wouldnt really be much point in having a dual from the cat back on a single turbo engine would there?

Twins do look pretty cool though.

Well yes they look cool and they would probably save you some ride height, 3.5" vs the height of a 2.5" see what I'm getting at?

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
