The colour on this wagon looks similar to the colour on my VS ute. And I agree it is an awesome colour.
Love the wagons VE SS with LSA block and 2650 Harrop. The wagons put power to ground very well
Sounds great. 25 HP is not to be sneezed at. Really liked the video.
One issue with getting the exhaust/extractors done is it increases the braking distances........as I found out when I overshot my usual turnoff on the way home from the shop. 🙂
Fitting just a VCM OTR complete with MAF sensor leads knocked about 2 litres per 100 km off the fuel consumption of my VE SS for highway driving...... when I did get it serviced..... the first the mechanic did was call me. I to take the original air intake down for them to fit as it was running way too lean.
That's insane, what a result for a simple exhaust swap
It would've been interesting doing a std airbox to otr comparison with the std exhaust so we could see how restrictive it is? But loved the video 🤔
Would have been good but owner wasnt fussed on spending the extra money. He was just chasing the sound 👍
I've recently had the same setup put on my Ve SS ute but with the otr. Same colour even. My mechanic played with the parameters but no tune. So this video was perfect for me. Thank you
Sounds great!! I'm sure those extractors we're the bulk of the gains. Would be interesting to see what it could make with a proper tune!
Sounds awesome & 35 hp amazing difference thanks for your content always interesting 👌🏻👍
Surprising results for sure on this cool family truckster!
Good video 👍🏻
I don’t know why the owner wouldn’t also get the car tuned and also fit an OTR.
Personally I’m not a fan of the X Force exhausts, but they are cheaper than some of the other big name brands. This wagon did sound not too bad though.
As I watch this video with my ve 6L wagon sitting beside me, I'm thinking I really need a tune with my OTR and 2.5 inch xforce exhaust 😮
Good vid fellas, as I have looked for content that covers this on a VE, VF. I’d love to see the results after the tune.
Top job ! Thanks for doing this !
Gotta love the l.s..wish I had the money to turbo my ve.
In the USA this is the Cadillac CTS-V LS3 supercharged 556 Hp or 490 at the tires (tyres) hot little Sports Wagon.
you guys nailed it
Stock systems are just ridiculously restrictive, I was honestly expecting more power than that. Easier airflow out makes a difference, with a tune and OTR intake would make a huge difference!
You literally just answered your own question. Making 25hp without a tune is pretty good. Otr and tune has been shown many times to make a even bigger difference
@@spaghetti5038 I never asked a question!
This has been interesting Max as to materials (304/316/409), so we might have to go into detail regarding this. 😉
Sounds good but I prefer my BORLA system without resonator
What's not to like about the Calias? It's fitted with a slushbox!!!
My previous Ute was a VFII SSV Ute.
It had a mild steel 2.5 XForce placed on it from new.
At around 100,000kms the mild steel rusted out.
I was selling the car so placed a factory exhaust back on.
It felt like the car was absolutely strangled.
Any view of how a collectors and exhaust work on a VFII LS3 ??
Wouldn’t the 200k spark plugs account for some of that power lose as well ?
Exactly what I was thinking too
Although most other dyno vids of stock 6l are about the same rating, so not overly surprised to see a 30hp gain from the mods
Not really. Unless they were having issues with spark breaking down it doesnt make all that much difference.
I have the exact same intake on my WN s2 Caprice. Did Holden not change them between the L77 and LS3? And is the only difference between them just the engine. Or is cooling, diffs, etc all that different as well
be great to see same car with tune now :)
thats a good vid boys would the pcm corrections not be able to re adjust the afrs in the PE mode is that because there out of there ranges ????
I really hope he got it tuned
big questions here as i have an HSV wagon in the states. how much "better" is the exhaust and tune on and HSV clubsport tourer? also, can anyone point me to a good plug-in tuner as im not sure i have anyone to tune it here
XForce hey...nice,got the same exhaust on mine
Hi Guys
Love your work - what plugs and leads do you recommend for the L98 - can I buy some from you?
Very surprising stuff
how long did it take to install just the headers?
also id say this car would be throwing every o2 sensor code under the sun which would be enough to warrant unlocking the pcm to tune it
as the engine light always popping up is anoyying asf
We were not expecting that 😂🤣
Is the HP and leaner because of the extractors … to cast manifolds. Mine has a OTR. Cat back and tune and 348rrhp think 256kw ….
Grate Vid. Question. Are wagon and ute exhausts the same length?
I thought you had to tune the engine when putting extractors on ve 6.0? Doesn’t the engine light come on?
If I was the owner I wouldn’t be leaving those fuel ratios. I’d be heavily suggesting to him.
@@alexandersupertramp1293 double what? I’m not taking about the power it made. It’s the fact that at WOT it look like 14.1 afr
It was heavily suggested. However even at those AFR at WOT with std timing it wasnt showing any alarming KR. Even so the owner of this particular car is no hoon, it will hardly ever see WOT and at cruise o2 trims will do their thing. So for him it was't worth the money
Did it throw an engine light with the extractors and cats?
In your opinion without been biased, would you highly recommend XForce? Any droning sound inside the vehicle when driving due to the new exhaust?
mate it depends if you have a wagon, Ute or sedan. If you have an sv6. Get the 2.25. It has an H pipe. Compared to the bigger 2.5 and 3 inch ones. Most sv6’s sound awful because they pick the bigger exhaust options. Pick cat backs that have 2.25”/2 1/4 inch inlets.
@@wizzfizz6800 I’ve got a VE SSV Special Edition (sedan) I’ve had the AFM disconnected and returned.
@@MrClemmo13 Get a Hurricane or manta catback. Xforce is pot metal compared to them. Plus when you tell people you got something that isn’t xforce, they will smile haha. It’s an SSV mate , treat it with a nice catback. Not an affordable one
@@wizzfizz6800 Thanks for that recommendation!
Do they sound similar to a di fillipo system
Which component of the exhaust would have made the most difference to flow? Headers/cats or midpipe and rear mufflers?
Header's
Did it get tuned and did you make another video?
I got same x force system but 3inch.
Stock intake with k&n panel filter.
Dyno tuned to 386hp at wheels.
So plus 100hp or so from stock
No never got tuned, owner didn't want to go that far with it unfortunately.
Just tickle the power enrichment and done, probably run a bit leaner on the street
Have to pay licensing fees to do so which owner wasn't keen on
Mad
how much do you charge for tuning?
Quick question, I installed a full diFillipo exhaust system and CAI to my LS3 and haven't had it tuned yet!! would that be the cause of the engine light coming on and saying the rear O2's aren't working? I can clear the codes, drive for an hour or so or days, then the engine light comes back on, then rinse and repeat and it's good again. The car drives no different with the engine light on or off, I did check and was informed no harm can be done with the rear O2's tripping the engine light, So will a tune fix this problem or do you think the the rear O2's might be faulty? cheers Max
It can just be a minor exhaust leek and your sensors are working fine.
Or not enough back pressure. Get it pluged in at a mechanic they can test the sensors
Did you try a poor man's tune?
A bit late now, but the answer is yes. The sensors aren't reading the range the ecu expects, common issue with the ve/vf.
@@JordyValentine So will a tune fix the problem or are the sensors faulty.
@@keevasmybitch yep, needs a tune mate. A tuner who knows these cars well will already be familiar with it. If you have a google you'll find a thousand people have come across this problem before. Once you move the position of the sensors by fitting a new exhaust they'll read differently than the ecu expects and throw a code.
Dam, I have a walkinshaw 2.5 with inch and 3 quarter headers sitting under the patio, should probly put them up for sale
what state?
Sweet🤘
I'd love a VE wagon but can't afford a LS. Would you go near a alloytec??
Doesn't have that crappy annoying bark ls has in VT to vf which sound terrible you can always tell when someone spent the money and put high flow cat
where are you located?
What about drone , is there any .?
With DOD yes there is, quite bad actually. Wouldnt recommend doing an exhaust without deleting DOD from the ECU at a minimum
Yewww
X force sounds pretty ordinary in my opinion, think you would have been better with a pacemaker or if the budget was open DiFilippo is the way to go.
Depends on the series and material. The 409 systems sound great IMO
Darcy’s head torch habbit rubbed off on ya?
Just want to make him feel welcome so he keeps coming back
*Imagine having a 6.O V8 that only makes 275hp@ the wheels. That's embarrassing...truly embarrassing.*
Better not buy one then
@@BoostGumps I definitely won't be. Years ago I had a BF XT Falcon 4.O 6 cylinder (N/A) as my daily and that made 218hp@ the wheels. So an extra 2 litres and 2 extra cylinders made only 57hp more.
Like I said...that's truly embarrassing for a 6.O V8.
@@victorpeirce4753 “only” 57hp? Thats over 25%, thats a massive difference.
I got 355 with the same system besides I didn’t get the middle muffler and added an otr with a tune
Same with mine till I opened it up. Though mine is 17/8 with 3” all the way. No center muffler
362 , otr, tune, headers, with no X pipe (true dual) 2.5"
But you changed the old plugs. That's y. So put old plugs back in and see
As long as its not blowing out spark, new plugs will make minimal difference to power figures
@@BoostGumps i dunno about that man. When i put new plugs in a car with 100k plus plugs in it it feels like alot more power. Especially torque. As for extractors theres a mathematical equation to work out witch runner length and size based off cam specs. Mainly to do with a thing called valve overlap . Witch is crucial to get the 100% out of your engine without adversely effecting what little atmospheric pressure there is for a na engine. Eg atmospheric preesure is 7 psi. With correct valve overlap occurring with correct extractors , manifold , headers brings the it upto 14psi due to a correct vacuum achieved thanks to valve ovelap
@@backyardbangers1012 I do…
Most of that is incorrect. What youre trying to optimise is flow. The correct size and length headers, as well as collector design, are based around cylinder scavenging during exhaust valve events allowing for maximum cylinder filling. Intake runners can be optimised the same way. Atmospheric is 1 bar is 14.7psi, not 7psi. Overlap has nothing to do with this.
A lack of engine flow due to incorrect manifold design will not cause vacuum, quite the contrary.
@@backyardbangers1012 the heck do you mean valve overlap?
We never took the heads off to lap the valves
And there is only 2 in each cylinder they’re very seperate how can they possibly overlap???
@@rexosp31 overlap refers to the time when the intake and exhaust valves are both open. It becomes important when changing cams and looking at lobe separation angles.
Now tune it ffs
turn off DOD at least
Why?
@@BoostGumps custom exhaust tends drone when afm kicks in. the stock exhaust system is a tuned length to minimise the drone on 4 cylinders
@@3lohssvrm the stock manifolds are about the furthest you can get from tuned length. Regardless, tuned length is about cylinder scavenging. If done correctly it makes no difference weather the the bank is operating on 2 or 4 cylinders it should still scavenge very similar.
@@BoostGumps maybe tuned length was the wrong term to use, i meant the whole length of the exhaust to the tips. agreed the manifolds make no difference. The stock rear mufflers loop around internally to mitigate the resonance. Its purely a nvh thing not performance.
Yeh thats fair enough. This particular car hardly had any drone. A little window between 1800-2000 RPM, but at cruise it was dead quiet. You would hardly guess it had an exhaust system at cruise, can only hear it in the car when you get up it.
200kw wow that’s embarrassing a pile of junk aurion makes close to that atw with 2 less cylinders and 100% more reliability 😂
Mate, It’s a pushrod V8. It doesn’t get much more reliable that these 😆
The aurion is a gutless shitbox and not that reliable either you are dribbling 💩
