• 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.

Airedale tough!
Color: Rubber Chew Toy, Size: Large
We have two young Airedale Terriers and I thought this would be a good inside toy for them to tug. And I was right! Very happily so. I have to admit I was surprised when I first saw it; it seemed so small. But the thing stretches and springs back to shape. We’ve had it about 2 weeks now and it is constantly played with. Absolutely the best toy! Very interactive either alone (it rolls) or with us or they play together. I am surprised how tough it is with all the constant rough play. Highly recommend!!!

Small, but twisty and fun looking. Seems relatively sturdy, though doesn't look indestructible at all.
Color: Rubber Chew Toy, Size: Large
SLIGHTLY disappointed because I thought this was bigger than it is. If you squish it all in close, it's maybe one and a half times the size of a tennis ball. (Of course, the size is probably listed; I think I just assumed, so my fault.) That being said, it's entertainingly twisty and squishy, though the rubber seems relatively sturdy. I'm not yet positive if it will hold up to the 8 month retriever/lab mix it's intended for; he tends to rip instantly through anything much less sturdy than kong natural rubber. But it seems like something that will amuse him, so we're going to give it a shot at Christmas.

Great product!
Color: Rubber Chew Toy, Size: Large
My dog is an aggressive chewer. I have bought this 3 times for her she loves to play tug and fetch with it. They last longer than most of the other toys I get her and it’s one of her favorites.

It’s okay I guess
Color: Rubber Chew Toy, Size: Large
Good price and decent toy, seems well made. My puppy is entirely uninterested and doesn’t play with it at all.
