Exhaust acutator thing in my GTB exhaust

[Guest]

Hey just wondering in my GT-B, if the wire cable for the exhaust butterfly thing is cut/snipped does this mean the butterfly thing is jammed open permanently? sorry, dont know how to add a pic in here

[Joker]

normally closed, when it actuates it open

[Guest]

oh sweet so how do I make it so its permanently open, do I just pull the hole thing out?

[Joker]

Pass mine still has actuator but no butterfly, can be handy 2keep noise down, good for flow in higher rev range

[RSB]

Theres a little notch where the cable attaches to the actuator. In an Rsb its in the left hand side of tbe boot where the jack goes. Pull the cable up from its current location and hook it into the notch. This leaves the valve permanently open.

The one in mines been cut, If I want control, I'll be needing a new cable...

as said be super handy for passing noise tests

people are actually trying to reinstall these types of systems into their cars which is ILLEGAL

so I reckon best keep it if you can

Only if it was never fitted in the first place. If it has been fitted and removed you can reinstall it completely legally...

Whats the legality around using a varex muffler controlled by the factory actuator? Would sound rather funny... fake VTEC anyone?

Reading through the LVVTA standards I'm going to revise my position

 

Exhaust system interference

2.1(3) An exhaust system fitted to a low volume vehicle must be designed, constructed,

and fitted in such a way that:

(a) the exhaust system, or components within the exhaust system, cannot be

removed, altered, or interfered with, without the use of hand tools; or

(b) the performance or operation of the exhaust system cannot be altered

from inside the vehicle, or whilst the vehicle is in motion, in such a way

that the decibel levels specified in 2.9 are exceeded, unless the vehicle is

fitted with such a system as original equipment.

http://www.lvvta.org.nz/documents/standards/LVVTA_STD_Exhaust_Noise_Emissions.pdf

Such a system may be fitted to ANY vehicle provided that at it's loudest setting it doesn't exceed the noise limits.

I did modify both the Factory and a After market muffler. I welded an old toyota dyna engine brake butterfly valve into the inlet of a cheap Cannon muffler, hook up the acutator cable and added a change over switch to the single wire of the controller so it either let car ECU control the valve or switch between 25% open or 100%open.

Due to the cheap Muffler it didnt sound as good as I wanted. Then I found another muffler for cheap and stayed with that.

As my car was still on Yearly WOF's I never tried to go for a WOF with this setup

Mine was cut as well, I unclipped the cable from were its attached on the exhaust and removed the spring that closes the valve & used some wire to hold it open, on the stock exhaust its still pretty quiet
