APR Presents: Audi TT RS 2.5 TFSI RSC Exhaust System & Stage II ECU Upgrade!

[Arin@APR]

Product Page

APR is pleased to announce RSC™ Technology is now available for the Audi 2.5 TFSI TT RS in our Performance Exhaust System. APR's RSC™ Exhaust System is capable of delivering gains of 99 HP @ 4,800 RPM and 113 FT-LBS @ 4,500 RPM when combined with APR's Stage II ECU Upgrade and is fully compatible with APR's upcoming Stage III Turbocharger System.



RSC™, Reflective Sound Cancellation, allows for maximum exhaust gas flow while completely eliminating unwanted in-cabin sound resonance known as "drone". RSC™ incorporates innovative technologies developed in conjunction with NASA. With limited use of packing materials and no baffles, RSC™ allows for a completely straight and free-flowing exhaust path throughout the RSC™ mufflers. Reflective Cancellation bounces the undesirable sound waves into each other to attenuate the wave and completely eliminate the low-frequency tones that create drone. Each RSC™ muffler is tuned to eliminate specific, undesirable sound frequencies allowing only the engine's true and desirable exhaust note to be heard and improving performance.

Turboback Exhaust System


APR's RSC™ Turboback Exhaust System replaces the entire factory exhaust with a High-Flow, Reflective-Sound-Canceling, mandrel-bent, stainless-steel design with minimal bends and no restrictive baffling or valving to impede exhaust flow. Beginning as a 4" v-band system, the exhaust smoothly transitions into a single 3" design with a high flow catalytic converter. Unwanted exhaust notes are cancelled out through the first RSC™ chamber before transitioning into a dual 2.5" design. Drone is completely removed as the exhaust travels through the rear RSC™ chambers before exiting the vehicle. You're left with the true sound of the Audi turbocharged 5-cylinder-engine and thanks to the RSC™'s free-flowing design, power and torque are greatly increased. The APR Turboback Exhaust System is a combination of the APR Downpipe and Catback Exhaust System, however each part may be purchased separately for use with your factory components.



Downpipe Exhaust System


APR's design specifications and manufacturing requirements resulted in a 4" v-band turbo outlet with a smooth transition into a 3" mandrel-bent stainless-steel design. The APR RSC™ Downpipe features a high-flow 200-cell metal matrix catalyst and connects seamlessly with the APR RSC™ or factory catback exhaust system. When connecting to the factory catback exhaust system, the downpipe splits from a 3" design to a dual 2.5" system after the secondary catalysts. Alternatively, when used as a full APR RSC™ Turboback Exhaust System, the downpipe remains as a 3" system and connects directly to the APR RSC™ Catback Exhaust. In either setup, no cutting or welding is necessary as the system is a direct fit and includes all necessary components for connecting to either the factory catback or APR RSC™ Catback.



Catback Exhaust System


APR's RSC™ Catback Exhaust begins as a 3" design and splits to a dual 2.5" design for each exhaust outlet. Smooth and unrestricted transitions at the splitter ensure exhaust velocity is not hindered. The mandrel-bent stainless-steel design is free of restrictions thanks to APR's RSC™ Technology found in each chamber. Three straight-through RSC™ chambers are specifically tuned to remove undesirable sound frequencies, "drone", from the cabin resulting in only the engine's true and desirable exhaust note. Expect quiet operation at low speeds and idle with nearly no in-cabin noise and experience the classic Audi 5-cylinder turbocharged exhaust note the second you mash the accelerator. The exhaust note is controlled by your right foot and does not require valving to restrict exhaust flow in an effort to reduce noise. The Catback Exhaust System does not alter any factory emissions components so it's emissions-testing friendly.

Each configuration is constructed from low-carbon stainless-steel with high-precision jewelry-grade TIG welding and high-precision CNC MIG-welded components. High-Strength Torca exhaust clamps ensure leak-proof operation through the unrestricted design and a lifetime warranty ensures years of worry-free operation. To better understand the components included with each system, please click the Exhaust Overview buttons below.

APR Stage II ECU Upgrade

The APR TT RS Turboback and Downpipe exhaust system is fully compatible with APR's Stage II ECU Upgrade. Stage II is a free upgrade for existing APR Stage I ECU Customers and is designed to maximize power output from the 2.5 TFSI Engine when coupled with the free flowing exhaust system. With lower exhaust gas temperature and unrestricted exhaust flow, APR's engineers are able to safely extract more power while working within the OEM and Tier 1 Supplier specifications for engine component stress tolerances and performance specifications. Turbocharger lag is reduced resulting in quicker acceleration every time you press the throttle! Click the tabs below to see the gains!

No requirement for a FMIC for stage 2...interesting!

can I just get down pipe and use exciting sports exhaust and get stage 2 tune ?

[as350]

Nice!

Yes

[Nitek13TT]

Hello Arin! couple of questions for you.

430HP 464TQ - is that flywheel or at the tires?

Didnt AWE dyno the entire setup (FMIC + cat delete + full exhaust + giac) at 350whp on a mustang dyno?

Just trying to figure out who to go with when my RS arrives.

I Would love to see a side by side dyno comparison same day same dyno, both APR and AWE stage 2. Also interesting is no FMIC with APR. Is AWE suggesting extra parts for something not needed for stage 2?

Thanks in advance!

Awesome! I ordered with the sport exhaust and was just going to do the stage 1 tune. Guess I might go for stage 2 now.

[Arin@APR]

Crank. Here's what we measured at the dyno (note, the gains are the same at the crank or wheels):

I haven't followed them, so I do not know.

[Nitek13TT]

Thanks for the fast reply Arin.

The gains are looking great!

More videos of drive away / drive by under load would be great if you all have time.

Sound from the cameras POV specifically.

[sentari]

How is it that the Dyno is showing 375 HP stock? I thought it was rated at 360. The
Price for the new exhaust looks fair. Mine for the 3.2 was a bit more.

[Nitek13TT]

[QUOTE=sentari;78368199]How is it that the Dyno is showing 375 HP stock? I thought it was rated at 360. QUOTE]

I believe thats what they calculated as stock crank HP based off wheel hp numbers.

[sentari]

No doubt I like these products, if I had an RS i'd be in line. But it appears one really needs to ignore those (peak) numbers and look at the other posted numbers that show the difference from stock. The web site has all that information.

It's time APR gave us a few snap shots of the graphs they are getting while building the stage III kit. Funny how for about 75K this car could destroy any p-car.

Amazing quality stuff! If I wasn't holding out for stage 3, I'd be all over this downpipe setup.

[YYC Dubber]

Great work once again, Arin!

Curious to know where exactly the downpipe connects to the OEM system?

From the diagram it appears I connects AFTER the secondary cat pipes...

(meaning no needs for cat delete pipes if that's correct....)

That seems to be the case. The primary cat is now located where the secondary cats had been previously. I wonder if the exhaust comes with extensions for the O2 sensor cables?

If you buy the downpipe only, it will connect AFTER the secondary cats, so it totally deletes all of the original catalytic converts in favor of our single cat setup.

Hey Arin,

Will the cat-back RSC exhaust be *required* for the stage 3? (I'm not sure why it would be, but I thought I'd ask).

Ditto.....


Id have already put in my preorder for this though.... but having over $3000 stolen from you is a kick in the nuts.

[Marty]

Are you sure that O2 extension cables are needed?

[Arin@APR]

They aren't

[joneze93tsi]

They aren't

Did anyone think after this long a detail like that would be missed?

NEW RSC EXHAUST*

*(Customers must buy or fabricate 02 extensions lol)

[YYC Dubber]

Awesome news, Arin. Nice to know you were able to get rid of those 3 restrictive cats and replace em all with a nice high flow design.

Was reading about your Golf R /Goodrich project car on FB, was wondering if you would consider producing a short throw shifter for the TTRS?


I would buy one in a heartbeat due to the quality of work you put into all your products.

I will speak with VWR to see if this is on their list. They have a range of TTRS products coming soon!

wooooo

[YYC Dubber]

With the RS using an all new 0A65 Gearbox, none of the old short shifters that worked on the other quattro 6mt cars work on it. (TT/TTS/Golf R)


Different variations of the 0A6 Gearbox were available in Europe in the following:•Volkswagen T5 Commercial carrier van.
•Volkswagen Tiguan 4-Motion manual (LMX gearbox code)

Hoping you guys can have a look at it and possibly modify the existing design to make it easier to develop bring to market.

For some reason i don't like the sound of it.
It's sounds to.....artificial, can't explain what's wrong with it, but i don't like it.

[JohnLZ7W]

Almost sounds like they were a gear too high all the way through the video, they seem to be lugging the engine

[ThatVdub]

Stalking the remote possibility of owning a TTRS, but if I were to, this exhaust would not be
something I would add to it. Arin, anyway to like make something similar to the MK4 R32
res and muffler, possibly yeilding a more growl than fffrrrrrrruuhhhh sound...

[Marty]

Sounds good to me. From the video, it doesn't sound like it will be one of those deep droning "boy racer" sounding exhausts. Though I have a feeling that, like for all of these exhausts, it's really hard to tell what they'll sound / feel like without hearing one in person.

Anybody have one of these on pre-order?

[sentari]

From a sound perspective, there is no replacement for displacement. Well, that's true for a lot o fthings.. But getting a 4-5 cylinder to sound like a ZR1 Corvette is just not going to happen.

not looking for a vette sound or loudness, looking something more closer twd an mkiv R32
sound, which I think the 2.5L can accomplish. wonder what it would sound like with an MK4 R32
muffler on it? maybe without a resonator at first? I LOVE displacement, plus add some turbo on
top, is yum!

apr doesn't even sound good on the 2L R, the scorpion does a better job.

I don't really care for a growl if the sound can be replaced with a turbine sound (ie the hpa FT360
kit on a stock R32 exhaust and intake sound), just not into the quiet forced rush of exhuast out
the pipe sound, that is just gross.

What you call gross, others call a great way to make power way beyond what a NA engine can do per Litre without reving the NA engine into the stratosphere. I went from a 2012 Mustang GT 5.0 6spd with a Corsa axle back exhaust to 2012 Audi TT-RS. Though the Corsa exhaust sounded great, I wouldn't want to give up the TT-RS, even if it has a 'forced rush of exhaust' from the turbo

Any info on power/torque gains for the full turbo-back exhaust system with stock ECU for those like myself unwilling to go for an ECU reflash until warranty expires? Thx!
