Variable silencing system I think it stands for.

It's a system to restrict the amount of air through the exhaust to quieten the car for silent mode. Might want to check if the valve is actually stuck or not as due to being in the exhaust they tend to get stuck in one position a lot.

Since my exhaust is still looked as something stock (I'm not sure about this actually), I'm going to test it soon (I've done it before but I didn't realize somethin' different).. By the way, is it a standard feature for this type of skyline? Thanks! :)

I think you're right, NJR 34GTT.. So it should give a significant change to the sound?? :( One member of skylineowners.com in UK also said that it is common for this optional system to be got stuck.. I will investigate this as soon as possible.. :)

m-p,

I have a 98 R34 GT-T semi-auto too & mine that switch!

If you switch from Silent to Sports mode, there is a noticeable difference. The exhaust note adopts a growl to it - not as loud though as a cannon type exhaust you see on many Skylines & Rex's.

You can tell the difference just parking & switching between the two, but more so when you "load the car up" driving up a hill, then swtch to sports mode.

My girl gets scared when I boot it up a hill (she's not really a car person, unfortunately!), but relaxes a bit when you switch it to silent.

If you check the exhaust just under the rear bumper, you will most likely see two pipes of different diameters feeding the exhaust itself. There must be a valve that the switches controls to toggle between the two.

Mine is a Nismo exhaust (brand stamped on the underside of the exhaust), so I'm thinking it may well have been a factory option.

Wow.. Great, Mean_R34! Seems that it really works in your skyline, so I think I must check my system and have a test soon.. :P I can't perform the check right now because it's already late nite, and seems that it's so dark outside (everybody knows that.. :P ).. Thanks! :(

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
