What category of racing and where?

I'll come and watch.

Hope the poofteenth of a kW power you gain from removing the cat makes a difference.

spoken like someone who has never run a cat-out pipe, they make a noticeable difference to mid range and throttle response.

D1 Garage in SA can get them for you as well www.d1garage.com

Another option is get an exhaust shop to weld a pipe through an old cat, a mate got it done in SA for $40 - bashing the guts out doesnt tend to have the same results from what I have been told (by tilbrook auto and dyno in SA).

gazza, cats are pretty much a standard size on nissan.

Yep! It's basic physics I guess eh :) When exhaust gases are allowed to expand a few inches either way (in a bashed out cat) they slow down, then must also rapidly speed up to exit the cat again. Not very efficient, and definitely not as efficient as a straight pipe that maintains the diameter which keeps the gases flowing the same speed.

Pipes mine !!! hehe, Thanks gazza750, lol R34 It is actually going on an track spec r32 to replace a collapsed compliance cat so chill, also just for amusement, take a look at nz they dont have to run cats by law, they have done tests, a car in decent condition with a decent tune can still pass an emissions test, And, after around 60thousand kays, Cats are saturated and filter out nothing if not they add to the emissions, so there,

    • Haha, i kow right? Could have bought so many cars for the same amount of money (or less) but driving Unicorn gives you at least +1mln to style 😅. Like wise man said "life's to short to drink cheap wine and drive boring cars" 😉
    • 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  
    • Hey all  im wondering if you can help me please I have put a rb20 box in my r34 gtt as my auto packed up and a friend had a spare box I know it’s not ideal but it will get me up and running for now. we have done the conversation and everything is working great but my Speedo we got a s13 speed sensor but my Speedo reads double now and I bought a speed converter but still not having any luck.  so I thought I’ll reach out and pick your brains  any help would be appreciated please as I wanna drive my car again 
    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • 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 🍻
