New noise regime.

There is a light blue Series 1/2 RX-7 that used to always drive past. Loudest one of the lot. I have not heard it in recent weeks.

Hurrah!!

It a dog slow pile of dung anyway.

Yeah well, they're getting long in the tooth now and the worst offenders are the ones modded by cocks that think drilling a few holes in the exhaust makes them sound/perform better when in fact they're fucking the exhaust system and shortening the life of the engine. They're also the cocks who drive them in a stupid fashion, damaging the engine and risking wrecking the car.

Soon the only RX7s alive will be the ones in pristine factory stock or sensibly modded by skilled enthusiasts and well looked after, not driven by fuckwits.

The retards are to a degree "self limiting" and the number of wankers driving RX7s will diminish to nothing. Regrettably, all this means - since they're too stupid to realise it was their own fault the car blew up or crashed - is that they will go from an RX7 to whatever the latest small-cock mobile is and carry on making a nuisance.

2500 for Sporty's. Read the file.

It wouldn't open on my computer.
Not that it would have done me any good any way, I can't read.

I'll take it back then. Bikey cop will read it for you.

Thanks, I'll bone up on it for want of a better expression.

Here is all the information and a list of certifiers that can certify your exhaust. Of course, getting it certified will be like getting any other modification certified. It's going to cost $$$.

Page 8 and 9 tell you the RPM level that your exhaust will be tested on depending on the type of engine you have.

BC.

Going from what Bykey Cop posted I read it as you only need certification if you fit an aftermarket exhaust, stock exhausts do not need certification. Have I read this right?

[Wired1]

Ok I read it. My XV has a four stroke twin cylinder motor with two valves per cylinder so that makes 2500 rpm. At that speed I could take the pipes off and it would be under 100dB just about. I am surprised to see that there will be a testing dude in Nelson as both my bikes have after market exhausts on them.

[Mooch]

I'm glad its 100db, the Duc should just squeeze through and that is with the standard exhaust...., gonna have to get a different muffler for track days though

yeh , but you'll need to make sure the clutch is pulled in during testing .... Dry clutch is gotta be worth another 10 db !.

Will be interesting for some of us Vtwin boys and girls with aftermarket pipes. A set of full Arrows or Termi's are around the 104 db mark, hopefully it doesn't produce that at 4,000 rpm. Mind you , only an issues if your pulled over .... whats the chances of that in this day and age ....

Hmmm, little green monster I'm on might be a tad over.
But I like the way it sets off car alarms...
