VAREX™ mufflers combine both the design technology of the stock muffler and the performance muffler into one single compact unit. A sophisticated butterfly valve mechanism is implemented to redirect the exhaust gas flow and vary be-tween the two. For higher sound level, the exhaust flows are directed through the opening path and produces maximum power with a robust sound level (or the “sports car note”) and near-zero resistance. - Авто та транспорт
I have VF-SSV which was one of the first off the production line in 2013. As a retired Superbike racer, I have to admit when I purchased the V8 (my 2nd new car) I was not that overly impressed with the note. One of the first things you learn about performance mods required for racing is breathing. Simply put, you cannot have your intake greater than your capacity to exhale. So I looked around at exhaust systems and came across the XForce Varex system. Variable exhaust back pressure has been used in street and racing motorcycles for quite some time. I had my system fitted (21/5" from the Cat back Stainless) straight away and I couldn't be happier with the results. When I come and it's late I quiet the exhaust down to what I considered very close to factory levels if not less. No annoyed neighbors and in traffic more peaceful. But, when you want to hear that real V8 roar its just a flick the switch and the difference is well worth experiencing. Next step, will be Over the radiator air intake, but I'm in no hurry as I have the best of both worlds. Nothing like being at a set of lights quiet and then someone pulls up beside you. Nonchantly, open up the flow and away you go and you hear the V8 growl as they wonder where that came from. Nearly 5 years old, and the result. I Love it!! It's the car equivalent of an Akrapovic or a Yoshimura bike performance exhaust.
Thanks man,I got the same varex 3" exhaust vf73 sed on me car, almost 6years.
Yep you can change the controls on a sec,good for early morning starts
🤔👍💯
I had Xforce on 2 of my cars, both exhausts cracked around welds, was probably the poorest quality I have seen. Unfortunately I tried them a second time and got the same issue.
Now I only use DiFilippo Exhausts. A bit more pricey but the sound quality and workmanship are second to none.
Also no fucking drone with Manta/DFE. Every Xforce pos exhaust i have heard has droned like crazy.
I have 3" cannon type Varex since 2012. Still working fine, no problems. In Russia where roads are commonly covered with salt in winter.
The Stock one pops and crackles and is loud enough for most people I also think it has better looking tips.
Would The oval style 3inch and dual outlet would be quieter than cannon style 3"? (both with valve closed)
Wouldn't it be a little restrictive having a tiny little gole for the exhaust gasses to get through?
What’s better for daily driving a Caprice 2013 is it 2.5 or 3 inches exhaust system?
Hello,in which material is made the bearings?titanium?graphite?
On the exhaust, there is a normal dc motor. How do you open %25, %50, %75?
sound like it has an exhaust leak with the butterfly closed - the sound of some air still escaping past the butterfly.....
You need to leave links to you’re website of what products you’re talking about
Hi, I've tried to find one for me Subaru WRX 2012 sedan
Do you v6 option.?
Super wydech pozdrawiam 👍👍😀
For all the ones that claim to have/had xforce and call it shit, did you go budget for the mild steel or go stainless steel for the extra bucks?
Stainless mate vf73sed with varex 3" exhaust.
Pretty good.🤔👍💯
What is the part number for the muffler with the anti drone canister? Would love to get a universal one for my 87 grand wagoneer!
Contact Xforce 👍
Yeah wouldnt go varex again. Still on my fgt xr6, lasted 1.5 years before I needed to replace my cat and high flow with limiter, as a part melted and damaged my 02sensor lol was nice but next project taking a different route.
They need more *Robots* :-P
Aren't those mufflers illegal in NSW? I know people that have been defected because of them.
If a butterfly operated exhaust isnt fitted to the car from factory then its illegal to install one apparently
Does these Varex butterfly valve rattle over time?
It hasn't in our car.
Wouldn't have that butterfly flap I'd have a straight threw.
So you basically choke off the exhaust and create a shit ton of back pressure? Am I wrong?
and the factory system doesn't?
thesamandnath I'm sure it does but the varex system is literally closing a solid flap of metal over the entire exhaust pipe. Stock doesn't do that. It uses the muffler to reduce the sound and flow of the exhaust, not just completely capping it off.
James Ritchie It only blocks the middle of the muffler off. This sort of thing has multiple uses, i.e no one like to come home late at night and wake the neighbours :)
Fullboost so are you saying that exhaust bypasses the middle pipe via other means?
James Ritchie When the muffler is closed it essentially works the same as a stock muffler does (the flows runs through the chamber of the muffler).
Why won’t Xforce even let you post comments on their UA-cam channel?
I have a question about using their headers on a Chevy SS reference the steering shaft being on the left vs the right side of the car.
Perhaps just contact them through thier website.
Are they legal?
Illegal in VIC and NSW
but why does everyone hate Xforce systems ?
Usually it's because they're too busy following everyone else's opinions so not to stand out of the crowd. They rarely own, seen or heard half the shit they bag, just gotta look like they're part of the flock. I've had xforce stainless with varex and can't fault them.
I had 3'' stainless xforce system on mi 08 crunch clubsport 'sounded tough I've sold it now , some people have no idea
They don't they just annoyed that they paid twice as much for worse sound i guess ?
I've had my xforce for 5 years now and its still going strong and sounds great.
I get the difillio is "technically" better quality but to me the sound muffled and not great at all.
In the end the steel is almost identical on all systems if you buy stainless or not. Its how well done the bends are and the welds that probably makes difillo and the more expensive ones "better" to some..........however...... its like buying expensive nike football boots only to get smashed by someone in no name brand ones.......... makes no diff in the end cept your pocket.
A full custom system build exactly for your motor and car is what is best. Its why every drag and racecar does it themself and doesnt "buy off the shelf" (unless ofc the rules for the series state you have to use this or that system)
Valves closed sounds like someone’s blowing raspberries
Sorry but sounded tinny and crook in quiet mode....
Their 4” variable muffler only has an 1 1/2” opening for the quite setting. I’m not an engineer but my common sense degree tells me that will be very restrictive even for a small car. Called xforce and their explanation was to not close the valve all the way. Ha I don’t think so. It got returned.
Sounds like chitty exhaust leak when closed
take a look at my videos , running a vy ls1 full 3" exhaust with headers and a straight pipe de cat and otr cai no tune tho :)
Lol poor xforce everyone hates on them.
this is for little girls, if you want your car to sound proper v8 you go straight thru twin s/s no mufflers.
and then get defected.
Well 2 years running strong :)
Fullboost he did say little girls. don't prove his point.
remote control cut out
Their varex mufflers don't sound that great. They dampened the V8 rumble on my LS1 so I ditched for for straight pipes.
Straight must sound pretty beast :D redback make good sounding mufflers though, so do xforce, I wouldn't go with anything else
an exhaust for posers if u want it to sound like a v8 super car ur gunna need a bit more than a muffler with a window wiper motor on it . nice set of extractors tho
LMFAO
my daewoo sound like v8 supercar coz I play the sound on stereo loud
There crap no more needs to be said.
Varex mufflers suck balls.
These products have no relation whatsoever to what's found on a V8 supercar, stop pretending they do.
Maybe because X-Force use kitchen sink grade steel and are made in China.
Di Filippo or Pacemaker use the right grade steel and should last as long as the car.
Another thing is that the Varex system is not EPA compliant.
Just bypass all this crap and get the 2016 VF SSV S2
+Ben McLarty Any aftermarket exhaust is not EPA compliant as the VE and VF stock exhausts sit at 89-90 decibels and we all know how shit quiet they are lol the police can straight up defect Varex on the street though without testing it.
I've got the VF 2 but stock is never enough sounds good but it's no aftermarket, my old VE had Xforce and it sounded good so can't knock them despite their reputation. Even Chinese grade steel is going to outlast the car I say if it sounds good then go for it, the only reason I want Walkinshaw is they offer manufacturers warranty, I honestly think KPM and Xforce sound better though
Not to mention when the flap mechanism gets chocked with carbon they dont open anymore making it useless
@@ashcosmo3854 You can be defected for running different profile tires if they are not listed on the ADR Compliance sheet for ANY vehicle, let alone tires and even fuel being used. Tints on screen, positioning of ANY item on inside of the windscreen. In short, there is pretty much no vehicle (NSW) that is above being defected once something has changed from when you drove off the showroom floor. The trick to avoiding getting fined or a defect notice regarding variable exhaust or open exhaust etc., or just being pulled over is really simple and easy.
Ensure brain engaged before starting the motor, and don't leave common sense in the toolbox before you head out.
@@stuarthablethwaite9297 Actually there are quite clear rules for what you can and can't do to your car. Valve operated exhaust is a clear no no. Stick to what you can legally do and you won't run into trouble. Tint, wheels engine modifications can all be done legally of you do it the proper way. These exhausts won't pass anything
@@ashcosmo3854 Appreciate your input. I have had it 5 years no probs or dramas, and trust me having owned a dealership there is a multitude of ways that can cause grief from mods if the HWP or RMS EPA decide to give a vehicle some close scrutiny. What I was trying to say is. Usually, the defect notice or fine is encountered by basically drawing adverse attention after a stupid stunt or act for the surrounding conditions. Not here to say what rules are right or wrong, more if people do stupid things then it's equally stupid not to expect the said fine or defect.
Point of variable exhaust - Yamaha EXUP (Production Motorcycles) around from late 80's early 90's for sure.
, there are quite a few other examples. As I said my point was how a vehicle is operated determines more than anything else usually.
Sorry but this sounds like something went wrong on the way.
First thing they should have done is get a real car. Not a Holden.
Second don't use Xforce shit pips and shit company that obviously knows nothing about how a V8 should sound like.
The exhaust system hadn't settled in. It had just been installed. It now sounds like a proper V8 after running it for a while.
Wow talk about attitude!
