Meh,Oops, meant to say Toyota and co not just Toyota. But the number made was small enough that my comment isn't that unfair.

Uhh Spokes WTF :eh: ?? An exhaust change is not a 2 minute fix. Plus its not possible for rally cars on a rally, servicing is only done a couple of times a day at most. The cars cannot stop after every single stage and swap exhausts just to drive to the next stage, then swap them again. Not gonna happen.

A car doesn't need a v8 to have power or to be fast, plus being able to go fast in only a straight line is a crap way for a car to be. Cornering is far more interesting than being able to run a sub-7 quarter mile. Drag racing? No thanks, rallying and circuit racing are vastly better. Oh, and btw, the hot rod folks are just as big a bunch of prats as the so called "import" drivers (a ridiculous name for them, especially as American and Aussie V8s are imported, in fact all production cars are imports, apart from the few built by Toyota in NZ factories years ago), illegal burnouts and bad behaviour are not just a boy racer thing.

My main concern is all the utter b/s being thrown about here about banning modded exhausts. Stock exhausts only? Excuse me? People do put on new exhausts for reasons other than noise. What happens to motorsport vehicles? They have to run stock exhuasts? Rally cars get crushed because they are noisy? The response that the controlling bodies of the motorsports come up with a solution is preposterous. MANZ is not the organisation who decides on car noise limits, that is the Government. MANZ can require that competition cars are quieter than the Govt's limits, but can't allow them to be louder.
Subjective analysis is a terrible solution, get a grumpy dick on the day, and you are screwed, the law should be fair. Overly loud is a wholly subjective term


Mate I drive a 74 Ford escort, I do appreciate things that are not V8 Buddy. And my point was, alot of these big engines are really muffled to help stop being so loud whereas these other "prats" chuck these absolutely fagged out exhausts on there car to make them sound the big and loud, completely different ideas. Rods have nothing to prove. As for being boring running sub 7, your very hard to satisfy arent ya pal?
again most of these guys would rather cruise the back roads than drag, infact the boy racers drag more than the rodders

Your good at being wrong. I said tail pipe. Easy swap. Or on rods Ive seen lever operated dump pipes, does the same thing. On one of my old race cars I ran a supertrap that shut it up for street use.

Just because its a "Race car" does not mean it gets special treatment.

Real race cars would be on trailers anyway. :D

Werent u talking about having limits for exhaust sizes not db's
And what about street rallys.
There is some commuting involved

Still its more logical to enforce current laws than have the government piss around for a while thinking aboiut it

Spokes, I know that you said tail pipe. The point is on motorsport vehicles the idea is unworkable. They are fairly pointless on circuit cars, since they get trailered to events generally. Rally cars are my issue. Every rally has a touring stage after it on public roads to get to the next stage, the cars must drive on the public road, they cannot be trailered there, and WOF regulations apply as soon as they hit public roads, thus exhausts would need to be changed. Rally cars aren't going to stop and change their pipe after each stage, and they are the ones on the road. I don't see why race cars don't/shouldn't get special treatment.

Most boy racers simply cruise around, races aren't as common as they are made out to be. As for your appreciation of non-v8's, your first post sure talks some smack about non-v8s. Muffling their cars? Interesting that you bring that one up after extolling the noise of 1500hp v8s.... Everyone likes different noises, and exhausts can be just as good a sound as a big engine to some people.

I personally think those big drainpipe exhausts are ridiculous, and banning exhausts based on size is a better idea than banning based on noise level. I'm just concerned about getting comp cars legal. Don't make all exhaust laws factory size, make certain sizes illegal

Just saying your generalisation of V8 and drags is not quite right seeing as many dont drag often it at all. Anyhow my pint was origionally how its hard for them to make these restrictions because these guys ruin it. Far off topic.
As for saying how loud a 1500hp engine is, no matter how you muffle it that thing will always sound like a 747. Not a good comparison to a jappa ;)

Did they ever find that person who was spraying expanding foam up the exhausts?

If they dont want to comply then dont run them on the street. Easy really.

Being a Rally car does not make them special.

spokes i think your special, and want to stick your nose into everything, and cause an argument. btw dw Joshguy01 your rally cars will still be allowed because they don't run a big bore muffler on them but a reasonably standard 2.5" straight through exhaust so will not be banned on size, rally and race cars are noisy bc of the performance upgrades on them, they are purely a performance car not a show car, a proper comp car, is not a common everyday driver car as they are not designed to handle at low speeds or on rough tarmac roads,

most hot rods are good looking, well restored, old american cars with there v8's producing high powered, low down torque, but yet again still not an everyday driver car because of petrol prices, hot rods are good for cruising the highways at speed on gentle corners and not generally a race track, and yet again this style of car don't have big bores ether.

The size isn't massive on rally cars no, but it often isn't factory standard. And the point made by Spokes was about non-standard sizes, not just big bores.

hay josh (Im guessing) my point is they are not much bigger than the standard size, so should not be effected by size restrictions, and these upgrades still need to be certified by Motor Sport New Zealand for them to get a W.O.F.

A Spoon muffler on an Integra was 114 db, with silencer in, it was 105db.
Stock intake and outlet diameter too.

Im am special. But Im also right. This argument of "race cars" having special rights is an old one and flawed. About 18 years ago when car certs ( I was to a small part involved in this as it started out being club based) were being started to be designed this was the argument and its still wrong. They dont have a right to be any different than any other car thats on the road.
