Variable EXHAUST switch system
Discussion

Its really quiet anyway due to the two rotary silencers. Are you sure it will make any difference?
Yes it should do, idea being to increase loudness/throatie sound like a straight through if you want to hear a great sound and then being able to silence her down if you want a quite run. ( Porsche have a factory option for them)gadgeroonie said:
you can buy a solenoid that will bypass your exhaust and vent it to atmosphere !
its basically a 12v solenoid that opens a flap
you could try an exhaust brake flap from a truck
This sounds very interesting thanks. Can you tell me more as i understand what you say but can't imagine how the pipe work would go and could it be variable?its basically a 12v solenoid that opens a flap

Has anyone fitted a Variable EXHAUST switch system like the Porsche, so you can change the amount of exhaust loudness from the drivers seat?:-)
If so, please can you give me details or any ideas where I may be able to get one (or two made) :-)
Just managed to locate one, will be fitting it next week. will keep you posted if anyone interested?If so, please can you give me details or any ideas where I may be able to get one (or two made) :-)

George,
I take it it's done then? Any photos yet? And costs?

Hi MartinI take it it's done then? Any photos yet? And costs?
Martin.
Yes, job now done thanks. The unit cost £150 and labour to fit including welding in/making the essential Y piece £120. First fitment we attached valve to a flange on Y piece which was good but I thought it would be even louder if we could get valve on flange to rear box. So after having to burn old corroded bolts off, we simply changed valve to rear box flange which enables me to close off completley entry to box and so sounds awesome, without being over the top:-) I have a photo if you can tell me how to attach to forum? or just let me have a email address. Regards George

Georgio
are you interested in testing it on the Dyno open and closed to see if it makes any difference ?
where did you buy the valve from ?
I purchased valve from Nemesis in Bromsgrove and really enjoying the option of extra sound:-) Re Dyno day - Probably will one day but not a priority at the moment as I have quite a lot of other things going on.are you interested in testing it on the Dyno open and closed to see if it makes any difference ?
where did you buy the valve from ?
Next on the list is a full Suspension/geometry set up, to make sure she stick to road with max. effect as I have noticed she is a little skitish on back end at high speed?

Can't see how it works from your pic?
Have you got two paths, one which doesn't go via the silencer?
The operation is from a switch by drivers seat, when I close valve it stops all exhaust gases going to rear box and diverts to new tail pipe from Y piece fitted:-) When the valve is open gases go to rear box and a few still go to new tail pipe which gives a little extra. Have you got two paths, one which doesn't go via the silencer?
I have also made up a blanking pipe to fit into new tailpipe which can be fitted in a couple of seconds, just in case I ever want to divert all to back box again? I can't really think I would ever want to do that apart from perhaps MOT time? George

from the sounds of the pipework you have described - I suspect it may be more restrictive than the original system.
but you certainly get the option to turn the sound down !
Your missing the point somewhere, as I now have the option of double the outlet, standard system or anywhere in between that suits.but you certainly get the option to turn the sound down !
