I am planning to machine a piece of stainless to sit inside the cat perfectly then weld in. finishing buy smothing off with a die grinder.

I guess it would be what you call a really high flowing cat :P

Spend a few hundred now and get a decent cat, or pay $10,000 later on for punching the cat out, i know which one i'd be doing.

qft.

Get a good exhaust shop to make you up an exhaust from turbo back, better still get one to make one from cylinder head back - they will want to know things like cam timing and turbo specifics, and it will probably cost a fair whack - But you'll have the best performance you are going to get on the street.

Also remember how people think. If you're driving around a show pony that just screams "book me" (or "race me" - they are the same thing) you are always going to get more hassles from your local law enforcement department.

You can have a performance exhaust with a cat, you just have to go about it the right way - like most things in life.

I would suggest that all of you who have or planning to punch out your cat go to the movies and see "An Inconvenient Truth" starring Al Gore. Or at least watch the trailer on yahoo or something. Freaking stirring stuff. It took a movie for me to actually stand up and give a shit about global warming...

Am i gonna join greenpeace or joing amnesty international or something? Hell No. But I will do my part to help prolong the life of this small planet.

"An Inconvenient Truth" = typical propaganda

lets leave that alone...

as for cat punching, well i had a 2.5" gutted on my car and changed to a 3" high-flow and noticed no difference in power

i even have the gutted 2.5" cat sitting my garage (in brisbane) if anyone wants to take it off my hands for $25 :P

I'm glad to see your doing your part to help global warming by intentionally losing your liscence. Well Done!!!

I have all 12 points on my licence thanks :D

Oh, and I also have a high flow perfomance catalytic converted... and last time I heard I couldn't lose points off my drivers licence for punching cats in the face...

So ummm... what the? ...what's with the hostility... hippy :) :lol:

Sorry Wilch...got you confused with mass_iv. You guys have such similar avatars!!!! No Hostility here...to you or mass.

Unless ur runnin big power a 3" high flow will do fine IMO. i have a pipe runnin through my cat on mine, and it was noticibly different from changing, still has the 02 sensor on the top so it looks like its still a cat...

the sound is mad, and either way getting attention from the cops from that sound is the last thing i gotta worry about since it happens as soon as they see the car, let alone hear it or even see under hood...

lol very true, typical american rubbish..like they know whats any good for the world, do they think about pollution when they start blowing everything up with missiles and bombs...no lol

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go. 
    • The roof is wrapped
    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
