Hey Guys,
I've got a good contact who can do us a good deal on Varex Mufflers for 5+ Sales. Retail is around $399 + Delivery, eBay sellers sell them for around $390 Delivered. I can Get the muffler kit for around $360 Delivered Aust Wide including GST. Full Australian Warranty and backup support from Xforce and this is local stock, not overseas.
This is based on the most common one for soarer - 3" inlet cannon, with 4.5" tip - this muffler is confirmed to be able to be fitted as a twin system on a soarer. I have been told by Fabian that the Oval system does not fit, so he had to go for a cannon which was spot on 
Youtube Video with EPA Noise Test. 81dB when closed (quiter than factory and 95dB fully open) : http://www.youtube.com/watch?v=K7jGYnhbQQU
Link: http://www.xforce.com.au/about-varex-remote-control-sports-muffler.php
I recommend the VMK2G-300 for a Twin system, twin turbo setup and VMK2G-250 for a Twin System V8. The 300 as a 3" inlet and the 250 has a 2.5" inlet.
Add your name here if you're interested. Once we get 5 people from around a few forums, I can make the order and delivery will be around 4-8 working days to your door after I have received stock. This deal will be going on the Supra forums as well.

Confirmed the ovals will not fit, unless you modify the boot and cut the pan out for the motors to fit. When I had them installed the exhaust shop mounted them on a 60 degree angle inwards to allow the motors to fit. They are a little bit more noticeable from behind as you can see the motors, but with the AC kit, it covers them up nicely. They also sit a little lower from the rear spoiler when compared to the stocks ones, but if mounted correctly the look awesome even with the stock body kit.
Costa, any chance you are able to source the VK02 controller which allows both mufflers to be controlled by the one unit? As at present you need to control each motor individually with different remotes...I could hack something up, but would rather just buy the unit. Was told they sell for $120 AU for the twin controller.
Also if you can, I am trying to source the VK05 controller which allows you to set the RPM level at which the mufflers open...but they are currently still testing the unit in Sydney. |

Fabian was that an answer for me? or ?? haha I was talking about the stock exhaust can I just put this on instead of what I have currently? I would need a elbow pipe made from the muffler to the bolt on joint but is that all or would there be more to do? |

Cheers Fab, I'll check up on the VK02 and VK05. I wouldn't mind the VK05 myself. You could even use a Hobbs pressure switch or an RPM activated relay to trigger the mechanism to open/shut as required.
Dejan, Not sure what you're referring to, but it could be connected to a stock exhaust, however it would be a bit pointless due to the poor performance from the stock exhaust. |

Hmm so what would i need to do and what would be the cost to get the best out of this My budget is really about $600 including the mufflers and what size would be better 2.5" or 3"? thanks Im a bit new to this whole performance thing, I like how we all help out here , there are no posts about this stuff on a 3.0l 2jz, So I leave it to the experts |

For a 2J non turbo, the best setup would be a single 3" Varex Muffler as mentioned fitted to a cat back pipe that would be custom made. That should get it to around $600-$700 including the muffler from the group buy, with the rest of the exhaust in press bent mild steel - depending on your local exhaust shop. You may also be able to buy a second hand exhaust system and retrofit this muffler to cheapen down the costs.
The only benefit of this muffler system is that you can make the car sound stock when you want it to, or loud when you want performance. This is a great thing for Victorians and anywhere else as you can shut the car up when pulling up to get breath tested or if you're getting pulled over etc.
Makes the car almost fly under the radar and then you can make it loud again at a touch of a button when required. It will not hurt the engine, even if you boost it, as the exhaust is still flowing, just through a 1.5" muffler system at the back when the valve is closed, instead of a 3" system.
Also very handy for keeping the neighbours happy if you have a loud car.
My supra is stupid loud as the dyno day guys can tell you. It's enough to make me tired / headaches with extended driving... so for me, I _NEED_ this system lol.
Those with aftermarket ECUs can use an RPM trigger to open/close the exhaust valve automatically without having to think about it. The VK05 box that is in testing will do just this, totally independent with its own computer and RPM signal.
I've paid for mine already so I've got it coming and I'll take some pics/vids of the setup before/after. |

I will look into it, your help was very helpful, I would rather keep the twin exhaust system though, and as for this group buy dos that mean $360 is for each muffler? |

Yep, $360 for each muffler, $720 for a pair for a twin system - Mufflers and control system only as advertised on their website
I'm looking forward to getting my hearing back lol! |

i have always wanted a set of these but when you buy two it gets bit pricey but as you said costa definitely need them.
can you do them with 2.5 inch inlet as mine splits into twin 2.5. what do you think the turnaround will be as i wont have the money for a few weeks as another rego due 
and see if they can do a deal if you buy two you get the twin controller |

Costa is there any chance of getting Variable mufflers that can be put anywhere on the system e.g not a variable cannon muffler, but say a variable muffler along the actual pipe.
Also is there anyway to have this open up with certain RPM/Load, like how many newer cars have variable exhausts that open up under high RPM or Load?
Thanks. |

Aaron - Yep the 2.5" Inlet Cannons are VMK2G-250
GB is for any muffler on the website list.
Boris, Round Varex Muffler
without Tip - I believe that these are the variable mufflers, without tip, that you can weld in to your existing system available in 2.5, 3 and 3.5 ". As mentioned, the VK05 system is in testing at the moment to have an independent opening to RPM, or you can use a hobbs pressure switch and relay to open it via boost pressure or your own RPM triggered relay with a Jaycar kit or similar.
Dejan, I can get them anytime, but if you want the cheaper price, it will have to be via the group buy |

Maybe, if you have a next round of mufflers I will be keen, I will have to get a cat back? exhaust system of some kind to get this to work, a guy at work mentioned that he can get me a 2.5" dual exhaust from the cat back for about $600 so I may go for that then upgrade the mufflers, unfortunately, i myself don't know whats the best option, as i don't know much about exhaust systems... thanks for the help though guys maybe if theres a second round in the future I would be very keen , I may ask you and maybe organize it with you thanks for all the help |

technically turning dollars into less noise when you want it. i have silencers in my exhaust and even tried some plates in the exhaust and the car runs like •••• with them and its still louder than my sisters na2j jza80 with a straight through (and cat) 2.5 inch exhaust. let alone with the silencers out lol |

Exactly, the Varex mufflers allow for performance or noise reduction on demand in 1 second. This is very handy for those that are looking at flying under the radar at a breath test stop or to keep the car quiet late night / around home etc.
I'll be installing mine tomorrow hopefully and uploading some pics/vids before/after

Very interested on the VK05, only way i'd consider buying one of these is if it has some automated control |

yeah they are very quick... one thing ive always wondered is a few of my mates have them and yes they muffle so much better but the motor assembly just looks like a chromed window motor. how much heat can they take before they start failing? and can you get parts for them if they do? as if you are punching out some power there will be alot of heat there. i was thinking putting some flanges near the rear so daily i can use the varex and if i get it to wakefield finally ill put the straight through ones on so the varex ones dont get cooked |

Was reading another thread and someone mentioned this:
Is it better to have the mufflers open and close via the RPM signal or to operate the butterfly valves from engine vacuum exclusively?
At least engine load is considered, rather than rpm based which can "trigger" at 20% throttle or 100% when only one really needs freer flowing mufflers.
Anyone able to shed some light on this? |

Vincent, I bought 5 in one hit and picked up, so my price was pretty much the same as the GB price, without delivery.
Fabian, I've installed and driven my Varex today in the Supra and I would say the control system, whilst interesting is a bit of a luxury feature. The Xforce muffler when it is open is 10x better than the supercat muffler that I had installed. It is quieter fully open than it was with the super cat! As such, I drive it on fully open now no worries, or half open if I CBF with the noise and fully closed if I am heading into hot spots / police. For response, I would recommend manual adjustment when needed. You will loose response if the muffler is fully closed and then it opens up again - effectively adding turbo lag to your equation.
I did the ultimate test on my way back from work, driving through swan st where the Usher concert was held at. 6x police controlling traffic at the main intersection on olympic blvd and batman ave - NOT ONE HEAD TURN AT ALL. Totally stealth. the BMW M3 near me was louder with their stock exhaust lol!
I love my Varex System. JOY! |

Just an update, that the vk05 rpm controller is available from varex in Sydney. Have ordered one and should be getting it early next week. Two options available, pickup via the alternator or an induction pickup from the ignition pack. Also for those with dual mufflers, there is a harness that allows you to use just one controller box to control both mufflers. RPM level is set and controlled via potentiometers. Will update further once I have it installed. |

Brett, I have considered this. I'm not too keen on it though, physically blocking the exhaust flow isn't a very good idea. That's why these mufflers are great, they divert the flow, much better! |

An update to the above vk05 controller. It doesn't seem to work on the Soarer and when speaking with the guys at Varex they said it is because the soarer is to well filtered so their unit can't pick up the rpm noise within the positive voltage line. Have tried directly from the battery and the same issue, I think the alternator on the soarer filters the signal before it actually leaves the alternator. So if there is any chance of getting it to work via the rpm signal noise then it will need to originate before the filtering circuit in the alternator. |

If i hadn't already built my twin system for my V8, I would look at one of the twin entry and twin exit mufflers, VMK30-250 or VMK31-300, and place it in the original centre muffler location. Then you could use whatever rear mufflers you wanted. |
