Whoever's they are - this is much more in line what I would expect in terms of DP gains and corresponding tune vs some of the lofty numbers others are hoping for on 'the other' thread. Minimal HP gains, decent torque gains.

That said, if a tuner found some other gains at the same time, or chose to push the turbo's a lot harder than prior, you'd logically see more significant gains.

[hubris]

The visceral sound emitted from DPs alone is worth the purchase. The bump in HP/TQ is a bonus! Impressive TQ numbers. APR mentioned significantly higher HP gains for their stage II/DPs on the Facebook announcement post for their product (in the comments), so I am looking forward to seeing their results "officially" announced.

Can we see the graphs overlaid (stage 1+/2) for better delta visualization?

Does the Unitronics Downpipe relocate the cat?

[VVG]

Thanks to Unitronic we now finally have some real world results to back up the performance gains of stage 2 software, downpipes, and catback:

Stage 2 with DPs/catback:





Stage 1+ with stock DPs/stock catback:



So the stage 2 software, DPs, and catback are worth 9 HP peak.

Unitronic's Stage 1+ software is already very well optimized as evidenced by their 11.4 @ 120-121 passes. So we now finally know the approximate gains of aftermarket downpipes, aftermarket catback and stage 2 software: 9 HP peak.

The peak hp gain appears to occur at approximately 4500rpm. Stage 1+ yields about a 100hp gain at this rpm. Stage 2 yields about 130hp gain at this rpm. So downpipes and Stage 2 tuning gives a maximal gain of about 30hp.

Do you think relocating the cats will result in more power?

Yes I do. It will allow a more aggressive tune

[VVG]

It's around 475 HP @ 4500 RPMs with Stage 1+ and 485 HP @ 4500 RPMs with Stage 2 as per the dyno sheets posted. That's 10 HP from downpipes, stage 2 tuning and the catback too.

4500 RPM gains won't mean much for those who race in the 1/4 mile or from a roll. As soon as you go WOT in any gear, the car never sees 4500 RPMs again.

Uhhh...no. I'm thinking more like 460-470hp vs about 495hp. The graph is hard to read to that level of detail quite honestly, but it is clearly more than 10hp gain. I was actually speculating about 20hp gain overall from this upgrade based on past experience.

Well spotted! Yes, there is a significant gain in hp anf tq at the lower RPM's.

[carymac]

On their website it states +131hp over stock for stage 1+ and +152hp over stock for stage 2+. Those are the numbers for the RS7, which proves that you net 20+ hp with a more aggressive tune suited for downpipes.

For the S6/S7 is where you only net 9+ HP

Dude, this is a big moment for Vol, don't ruin it. It's 10hp......

Once again, I don't recall anyone arguing with you about exactly how much HP you gain from the downpipes or the stage 2 software itself, but the reliability of the car running stage 2 on a stock exhaust.
Hence why both unitronic and apr (hopefully at some point) release their stage 2 software specifically for use with downpipes.

Shoot, I'd spend the money for the sound alone. And no, I'm not hacking up the akrapovic for a cheaper alternative solution.

A lot of people were arguing with me about that actually. Some people thought the gains would be 70 HP or more. Kouzman was expecting huge gains from stage 2.

With Unitronic there's no need to run the stage 2 software without the exhaust mods because the whole thing only adds 9 HP. That's because their stage 1+ software was already optimized for maximum power. With APR, however, it seems their 1.1 software isn't as strong. So that's why I would run the stage 2 software with the stock exhaust. I don't see how reliability could even be a topic of discussion. It's pretty obvious the factory exhaust pieces already flow extremely well and not a restriction. If anything running the APR Stage 2 software with the stock hardware may result in slightly less HP (1-2 maybe?) but it's not going to be any less reliable. If anything the factory cats will probably last longer than aftermarket cats.

So what you're saying is Unitronic basically is doing the exact thing you claim APR is, releasing a software that can work with factory exhaust system but are attaching a piece of hardware (which went through lots of R&D) to get more money out of everyone??

There must be a reason why both tuning groups have released their own hardware and not just milk profits by releasing the software and endorsing hardware that's already available.

I love how your arguments constantly change. You obviously have lots of time on hand to troll through this forum.

Kouzman was expecting huge gains from stage 2.

Once more when you quote me, use exactly what I said and not things that you imagine... I never said that I am expecting 70 hp from a stage 2. Plus you are comparing two different companies, two different products, two different dynos, etc...

I have stated IN WRITING that based on my estimations, the APR stage 2, downpipes and tune, can potentially increase the RS7 on racegas to probably about 40 awhp and equivalent torque if not more. This statement is post #64 back in January. That's weeks ago, before we even see almost over 10 pages worth of debates and nonsense assumptions. And in the same spot I am estimating the increases for the Roc-Euro intake which I eventually received and tested myself in real conditions. Not shop claims...

On a different note, I like Unitronic and I know that they have a good product, but I personally think the APR design has some benefits, i.e. moving the cars further from the turbos. having them close is good for emission purposes, they heat up faster, etc... Why do I have an opinion on that too Mr. Keyboard Warrior? because I have spent a few tens of thousands of dollars on modifying cars, from bullshit panel filters, two 3-4 different exhaust, downpipes, tunes, many turbos, etc... I was racing a 10sec pumpgas EVO for a long time...

I can post videos of 9 and 10 second cars that I've owned before in the past.

What was your 9 second car?

[kouzman]

You are hopeless my friend. Best of luck to you.

In the meantime I will just buy a few drums of racegas and continue my 10 sec saga since it only takes money and not skill. 27 10sec passes and counting...

I will wait to see your 10 sec runs and compare notes.

[CanuckRS]

Good because I already ordered a couple things for my car so the 10 second timeslip will come soon. Can't compare notes though because I paid cash for my car.

I think your matrix headlights on your rs7 gave you a lobotomy.

By the way other companies have release stage 2 few years ago and it clearly stated more than 9HP

You can get the same sound from modifying the stock exhaust system's resonators and/or mufflers.

You have zero clues what the heck you are talking about, our cars sounds ridiculously quite even with any catback exhaust on the market, AWE/MILLtek/IPE/Supersprint/Akra
It wasn’t until downpipe fully unlock the sound. To put it in Decibels WIDE OPEN THROTTLE term oem is probably 60, catback is roughly 80-85 and TURBOBACK with downpipe is 95 to 100 at least that was what mine was measured.
Catback exhaust give you excellent improvement during idle/mid rpm vs stock but have close to zero improve in high RPM. DP have about 50% improvement throughout.

It feels good to have these results as further confirmation that downpipes and catback add little to no power after dozens of people argued with me in the other thread for pages on end. I swear it seems like people argue with me just for the sake of arguing.
For those wondering, 9 HP in a car with a 4600lb race weight is good for roughly 3 hundreths of a second and 0.43 MPH in the 1/4 mile.

Vol 4.0T it’s sad that in your life you constant try to prove stage 2 makes zero power and its waste of money.
All you can see with your closed mind is 9hp peak gain however you failed to compare the two log and notice the gain THROUGHOUT the mid range.
Again your delusional is beyond believe because you think every other tuner is going to get the same 9hp result for their stage2 with downpipe, check JD Engineer and tell me what you see compare their dyno log for stage1 and 2? I guarantee you APR’s dyno will be different again.
Just in case you are so blind you didn’t see this already published numerous time AMS downpipe’s dyno already proven to increase 35hp.

Sorry not to bash the design of the downpipe of Unitronic I know you are great company but your dp design is literally identical to OEM which make sense to see very little gain.
I think many of us will have clear idea which downpipe they will buy base on the design, length cross over vs shorten straight down.

The fact is you VOL 4.0T prove NOTHING, you have a STOCK car. I have custom made downpipe looks similar Unitronic's one minus the cat and while the gain is not massive I could feel the mid range pull difference and my friend's 2015 GTR black edition can guarantee you I wasn't lying.

What does paying cash for your car have to do with anything?

[kouzman]

He said he wanted to compare notes. I don't have a note on my car since I paid cash for it so there's no note to compare.

[HeelBuff]

Hilarious.

Is there any possibility of hitting 10's with the stock turbo?

It's funny because OP bought an 80,000 mile S6 that was listed for like $38k. I don't care to get into E-thug arguments with trolls, but it is humorous to me.

[HeelBuff]

English must not be his first language. Idioms in foreign languages are especially difficult to learn. Huge benefit of the doubt.

[LINDW4LL]

Yeah it's so humorous that I did my research and got an excellent deal on my S6 nearly a year ago: 78K miles for $36K. It'll be even more humorous when, after spending about $5K in mods, I make the same power and run the same times as a tuned RS7 for less than half of what a used RS7 sells for.

Just to clarify Marc, I have nothing against you (or anyone) for buying a used S6. I think it's a shockingly good value, especially in your case.

That isn't what I was referring to.
