HIGHLIGHTS

• Gain up to 37whp / 42wtq
• Faster Turbo Spool 
• Improved Exhaust Note
• Fully Reversible

PROFILE

The ARM 4.0T Downpipes immediately improve backpressure in your exhaust system, allowing your Audi 4.0T turbos to spool faster and generate more power lower in the RPM range



The OEM 4.0T downpipes incorporate two large coffee can- size catalysts which reduce exhaust flow and power from your 4.0T.  By replacing your OEM 4.0T downpipes with the ARM 4.0T downpipes you will eliminate this restriction and free up exhaust flow.

Another drawback of the OEM downpipes is they are designed to cross over each other.  The driver side turbo connects to the passenger side midpipe, and vice versa on the opposite side.  This forces the exhaust gasses to take a long pathway with several sharp kinks and turns. The ARM 4.0T downpipes begin and end on the same side to improve airflow and shorten the travel-path of the exhaust gasses.  This results in faster turbo spool, more torque, and improved throttle response.  


CONSTRUCTION

 The ARM 4.0T Downpipes are built from SS304 stainless steel to ensure build strength and weld integrity for the life of your Audi 4.0T.  You will never need another set of downpipes again!



Starting at the turbos, the ARM 4.0T downpipes are made from one solid 4.4" x 3" collector for durability.  This collector is welded to an OEM-style 5-Bolt flange that will fit any turbocharger upgrade for the 4.0T platform.  






The ARM 4.0T Downpipes include a stainless steel flex section to relieve stress from the turbos during aggressive acceleration, cornering, and braking. 


The ARM 4.0T Downpipes utilize the OEM transmission mounting brackets to further secure them in place during aggressive driving.



The ARM 4.0T Downpipes transition to a 2.25" 3-Bolt flange to match up perfectly to the OEM Midpipes or the ARM 4.0T Midpipes.



NEXT-LEVEL EXHAUST HARMONICS

While the ARM 4.0T Downpipes enhance the sound of your exhaust dramatically, if you are looking to take your exhaust note to the next level, the ARM 4.0T Midpipes are an easy upgrade to further open up the incredible sound of your 4.0T. 



Audi designed the OEM midpipes with dual resonators to suppress the sound of your 4.0T.  While that may be desirable for some drivers, as an enthusiast you want to hear more of the amazing sound generated by the twin-turbo V8 under the bonnet.  The ARM 4.0T Midpipes do exactly that.  If you install the upgraded midpipes while installing the downpipes, it only adds approximately 10 minutes to the installation, making it the perfect time to install the midpipes.

Great color saturation
I have only used this a couple of times and was concerned about the dull colors when it printed out. But the listing warns you about that so I went ahead and pressed it. Perfect! Bold colors and high quality images. Plus, filling my printer only took a little over half the bottles. Great value for the money and I will definitely be ordering again.

Superior Customer Service; 100% prefect and functional, BUT...
Number of Items: 2
This product fits perfectly, after all it's just a simple piece replacement. The big deal is the counter reset, and this is where Customer Service outstands. People complaints about the difficulty of following the reset instructions, and with reason, as they are lengthy. But that is the printer you have, that is Epson's product. You either send the printer to them and pay the premium fee, or do it yourself, but you have to play their game. This is not Seller's fault; on the contrary, Seller put all their effort to include each and every steps you need to fix the problem, no matter what printer model you have. They included most, If not all, printer models you may have. They provided super detailed instructions to ensure your success; keys where needed, no keys where not needed, printer drivers location to download and ensure the resetter will work and, best of all, support if you need it. You have to contact them through Amazon asking for the user's manual (instructions; yes, the lengthy ones), the reset program and the reset keys if applicable (this depends on you printer model; some need the reset keys, some do not). And this is where you get concerned: When are they going to answer, now that my printer is locked? You think (I did): it is weekend, they will probably answer Monday or maybe Tuesday (after all, that already have the money, why care?). Well, I was absolutely wrong, they answered during the weekend with all necessary to have the printer back, up and running; Thank You. Some tips: 1. There is nothing wrong with the software (if got from a reputable source, and they for sure are), so get it without concerns. 2. Get the printer driver as advised; it is quite probable that the software will not work if you don't install the correct driver; don't forget to restart the computer after the driver installation. 3. Make sure your printer is set up with the USB connection Enabled (mine was disabled and that caused a headache: ET-4800). 4. When the resetter instructions call for Initialize the Counters, don't do it, not yet; select Check instead, just above Initialize. If you cannot read (Check) the counters, you will not be able to Initialize them: fix the connection problem first (make sure you installed the printer driver and RESTART the computer, make sure you enabled the USB connection in the printer, and make sure the usb cable is correctly connected). It's not Seller's fault to make long and complicated instructions, that is actually their effort to make sure you have all you need to succeed. Buy with confidence, this works: if you cannot make it work, you may find someone you trust to help you out (your kids or grandkids know a lot for sure), or just let Seller know, they are willing to help you out. Best regards.
