CR Sidepipes

[justbetter]

Guys,
Im gunna have to post here, i had a coppied version of ( work on the car when i've finished everone elses stuff, and then dreaming of future stuff for mine ) Mikes side pipes and they are not quiet enough to get the reg process. So the suggestion is to have a $hit house looking under body kit to get passed then throw on the live side pipes, i've tried a couple of versions now and run cats and mufler in the tube at the required length, and with out extending the length up like a truck stack some 1.8m high, doubt i can get any quieter.
Ah but i like it loud and have the 4 RTA slips to prove it with fines and mods last year costing over 4 k even now its quieter but not legal, sorry for the news. But have been busting for Mike to fire his magic motor up.

I think the days of trying to comply with noise regs on a modified car are over. There is a Classic Revival just completed in Sydney that had the legal system on at the last club meet. No one could believe how quiet it was. It sounded like a Corolla! To achieve the 100mm ground clearance the muffler was inside the rear wheel arch, and 15" x 7" wheels fitted.....

I am going to have manifolds made up to suit my live side pipes, but with a lower flange blanked off. For rego the side pipes will be blanked off and an underbody exhaust hooked up. At least this way the engineers certificate will show the side pipes fitted.

One of the reasons that I decided to build a Cobra is that if you are going to build a weekend car, it may as well be as grumpy, impractical, noisy, thirsty and have no roof.

Garrett,

my ears are still ringing from the test drive at Winton, and I think the mic on my video is shattered...... not quiet enough for rego.... geeze, not quiet enough for War Games

4 slips and 4k....


Not trying to be too pessimistic but I can see a potential problem if lots of people have loud side pipes or obvious mods for that matter. If some sh!thead from the RTA gets wind of all these loud, smelly & fast cobras then we could all be stuffed. Just ask 750HP (Craig)

It would be concerning if a few cobras got pulled up enough times to make somebody take a closer look at the cobra scene. All it takes is one RTA moron to come along to a meeting, take down a few number plates (or even just vet the RTA database) and bingo – audit notices are in the mail.

I’m all for having fun but I think when it comes to modding cobras, and lets face it, there are more than quite a few that are, I think we need to think globally instead of how deep our own pockets are.

I can think of no more obvious illegal mod than working sidepipes. There are more subtle ways to get HP.

Nassty, I hear what you're saying but if we are all encouraged to think on a global front wouldn't we be better off lobbying the powers that be to allow working SP's??? By this I mean if the HOT ROD fraternity can get their working side pipes plus a host of other "legal mods" OK'd, then why can't we.

It seems crazy as hot rods are all one offs. A modded cut and shut illegal derivitive of a once legal street car. None were ever homologenised in their respective HOT ROD form. In fact the truth be known they were illegal when these guys modded their cars 30 years ago!

My way of thinking is that at least Cobras were a real production run and all we're doing is trying to recreate what actually was???

This is off thread/topic I know, but I for one will be running working side pipes and will also prepared the results. I guess if you know what you create is illegal according to the ADR rules then you can't complain when you get pinged!

Nassty, sadly you're so right though... it only takes one inspector to create havoc for many!

Just my 2cents worth.

I agree with you too Spookypt re lobbying. That's been discussed many times. ATM though, changing the regs in the near future doesn't appear to be likely so we all have to make do with the current regs.

I'm not saying that modding is bad. All I'm saying is I think it would be better for cobras to be more subtle about their mods so as to not attract undue attention from the boys in blue. Loud doesn't necessarily equal fast. 400TT proved that at Shelby Fest 06. He was the quietest cobra there yet he was also the quickest.

Except for the blow-off valve, it was the noisest part. You could only hear it because the exhaust was silent. And it's all road legal, would be one of the few on that track that could say that. Even the turbo is approved. Also don't confuse me as the driver(my brother), I doubt I could pedal that Cobra that quick around the track. It scares me enough on the road.

Moves are happening up here in QLD already about getting changes made to the reg's. Les is involved in it. We've been basically backed into a corner by all the regulations in recent years and have little to lose, so are having our say.

From the drivers seat the blow off may be loud but from trackside it sounded like a gentle sneeze.

It's great that Les is looking into the issue! I'm sure he'll jump on this thread soon with some updates.

I have been reading everybodies comments about side pipes but can anybody tell me if you can actually get your car registered with working side pipes. It appears from most of the commemts that you have to register the vehicle with under body pipes, them install working pipes after reg.
