HELP: R34 GT-T VSS switch problem

[terry_valley]

Hello

the VSS (Variable silencer system) switch in my R34 no longer works. I checked the switch and it has power to it.

Does anyone have any ideas ?

the valve on the muffler could be stuck therefore the switch wont work cause the motor isnt strong enough to close or open it...get under the rear muffler and check it...u should be able to open and close it with ur hands...its right behind the muffler...u can see where the lever goes to

Also a quick question about this system...is it a large difference in sound? Or is it just there for w@nk factor?

Just I was looking at replacing my dodge exhaust with one that had this system fitted.

I've had a look around at this when I was looking at a Black R34 at Kamakazi motors.

That one was siezed.

Apparently, the valve often siezes closed and you have to attack it with WD40 to open it again.

Because of the heat in the exhaust it constantly dries up.

I wouldn't bother, very expensive and you would have to wire from the front of your car to the back and all sorts of things.

The one I was looking at was only $440 cat-back...wiring is no prob

is this a standard feature on all R34's??????? i've never heard of it before :confused: would my car have it?

[Bass Junky]

Ahh, Second hand yeah?

SS8, Not standard, an option. It's the Nismo Variable Sound Level rear muffler.

Has a valve that allows gas to flow either into the side of the muffler and hence through all the baffles, or straight through the muffler bypassing the baffles.

I've heard from some owners that it's a bit of trouble.

Yeah second hand....I'd only flog it up in no time if it was new
