MQB PERFORMANCE DOWNPIPE OVERVIEW
When upgrading your VW MK7 or Audi 8V A3 to stage 2 software you will also need to reduce the back pressure caused by the small diameter stock pipe. With the exhaust system flowing better performance gains be achieved. Turbo lag should also be reduced as an added benefit.
IE engineers guarantee a perfect fit by designing all IE downpipes in-house using the latest technology. Digital scanning is using to scan the entire environment which ensures that there is proper clearance and that all mounting points are in the correct location. Manufactured from 304 stainless offers a life-long product that brings performance and fun to the table for years to come.
POWER GAINS
The most power gains will be achieved when the IE Downpipe is paired with IE matching software, air intake, and FDS intercooler.
SOUND TUNING
An aggressive and drone-free sound will be emitted from the IE Cast Downpipe. This should be music to your ears! Thick wall tubing and cast sections remove much of “tinny” sound emitted by cheaper, thin wall, downpipes. With downpipes, you get what you pay for in terms of sounds and overall manufacturing quality.
HIGH-FLOW CATALYTIC CONVERTER
IE’s performance downpipe includes a high-flow 200 cell per inch metal matrix catalyst located as close to the turbo as possible. Metal matrix catalysts are higher performance because the matrix web is thinner, allowing higher flow in the same size. Our catalyst is also a very large diameter, allowing a large flow area and maximum power. By being placed close to the turbo, emissions and unwanted unpleasant smells are greatly reduced.
DIRECT BOLT-ON WITH PERFECT FITMENT
The IE downpipe replaces over 6 feet of restrictive factory exhaust tubing, all the way back to the OE “Cat-Back” rear section. Sturdy fabricated mounts and precise engineering result in a rattle free and long last replacement exhaust system. 3D scanning systems were employed to ensure perfect placement both in pre and post-production phases.

GOING STAGE 2 ON YOUR 2.5T?
Adding an Stage 2 ECU Tune and IE Downpipe to your Audi RS3 or TTRS is the ultimate choice power adder on the stock turbo & engine! Offering an aggressive and unique motorsport sound from your 5 cylinder turbo engine with complete unrestricted air flow for unmatched maximum power. Enjoy proven performance gains and leading features such as bolt-on direct fit install, long-life construction, cast sections, and amazing sound.
STOCK DOWNPIPES ROB HORSEPOWER
Your 2.5T engine is capable of supercar level horsepower on the stock engine and turbo reliably with a Stage 2 Tune alone! However, the factory installed downpipe is designed for maximum emissions and economy, not for power. This design is riddled with small piping, harsh bends, and power sucking restrictions that limit your power gains to only Stage 1 Tune levels. In order to correct that, a true performance downpipe is required to open up the exhaust flow and allow the turbo to spin freely!
MAXIMUM FLOW DOWNPIPE
IE engineers set out to design the ultimate downpipe option for the 8V RS3 and 8S TTRS chassis by employing leading-edge development technology along with highly specialized cast manufacturing. By using cast sections this allowed our engineers to design specialized shapes into the downpipe itself that lets it conform and fit into very tight spaces while retaining it's large size and maximized flow rates. The design is so specialized that 3D scanning was used to build a digital model of the chassis to design in allowing us to build shapes down to the millimeter. This design is just not possible using traditional stainless steel pipes and bends found in most exhaust manufacturing.
Bolting this downpipe onto your Audi along with other matching bolt-ons and an IE STage 2 Tune results in up to 577 horsepower! You can take your RS3 or TTRS from a sporty driver to a power monster in a single weekend. Downpipe requires Stage 2 Tune for a complete installation.
LET THAT 5 CYLINDER ROAR!
Your RS 2.5 TFSI engine has an amazing 5 cylinder sound that all enthusiasts love. Unfortunately, much of that sound is muffled by the factory downpipe system. The cast design of your IE downpipe creates an aggressive and deep tuned sound that showcases the unique rumble from the 5 cylinder turbo engine and transforms it into an all-out howling beast!
HIGH-FLOW CATALYTIC CONVERTER
By employing a high flow metal matrix catalytic converter, horsepower loss is almost non-existent for track days and drag events while keeping unpleasant smells and increased emissions to a minimum.
LONG-LIFE MANUFACTURING
IE Y-PIPE ADAPTER REQUIRED FOR STOCK CATBACK
This downpipe holds the seal of IE quality and has been manufactured to last as long as you own the vehicle and beyond. Constructed from 304 stainless steel and expertly tig welded for incredible reliability. The cast and CNC machined turbo flange is thick to prevent leaks or warping at the turbo while a quality flex section works to allow normal movement between the chassis and engine without adding strain to the downpipe.
IE's Y-Pipe Adapter Kit (sold separately) is used to adapt your IE Downpipe to a stock catback exhaust section. This high quality stainless steel cast adapter is a complete kit that will make installing our downpiep to your stock exhaust painless and easy! This part is not required if you are installing an IE Catback System.
BOLT-ON INSTALLATION
This downpipe kit bolts-on directly to either an IE Catback or stock catback (with adapter) with no permanent modifications or alterations to the vehicle. The removal of the factory downpipe is a very long process and is only recommended to be performed by a professional. DIY is not recommended for most on this product.

PRODUCT DETAILS
We were uncompromising in our quest to build the ultimate cold-air intake, the one we wanted for our own cars. Here’s why you’ll love it too:
POWER GAINS
On turbo engines more flow equals more power! Putting performance first, the ram air design, velocity stack, 3.5″ inlet pipe, and massive 5-inch filter all function to deliver the most power possible from an intake system. This Intake design delivers a massive flow increase over the stock air box, resulting in over 10 horsepower and torque over stock and far exceeds this on hybrid or large turbo setups.
MODULAR DESIGN
At the base of our intake is an alloy heat shield that spans the entire front of the car for maximum fresh air flow, seals off hot engine bay air, and securely holds the velocity stack and air filter. The modular design allows for an optional carbon fiber lid to be installed further sealing off the intake from radiant engine heat and provides a high-end gloss carbon finish to your engine bay.
PERFECT FITMENT & APPEARANCE
IE engineers utilize cutting edge 3D scanners and specialized software to create a digital model of the engine bay. This digital environment ensures the intake clears and fits exactly like a factory-installed unit. Rapid printed prototypes are then used to ensure fitment in actual vehicles before moving onto production. The result is an intake that provides a hassle-free install with angles and curves that not only look at home in your engine bay, but elevates the style completely.
FULLY INCLUSIVE KIT
Everything needed to install your new IE intake is included without having to make any trips to the hardware store or purchase additional add-on kits. Included is our stealth coolant line, which completely hides under the intake and out of view. This protects the coolant line from interfering or rubbing on anything that may lead to future coolant leaks. For vehicles equipped with secondary air injection (SAI) the IE intake is equipped to connect to the factory line without having to purchase an additional kit. Don’t have SAI? No worries, a plug is also included.
MOTORSPORT PERFORMANCE & SOUND
Delivering cooler air and in enough volume is a must for making power. To accomplish a ram-air design, our engineers utilize large piping and a velocity stack to efficiently deliver as much air as possible. We know a fast car is fun to drive, but a good sounding one really puts a smile on your face. The high-velocity bellmouth and free flow design of our intake also produces the exciting side effect of amplifying engine notes and turbo sounds that create a unique experience every time you push the the throttle down.
Due to the larger size of your new inlet pipe, this must be installed with an aftermarket intake. A new silicone adapter is supplied to be a direct fit with a IE Cold Air Intake, or most 3 inch cold air intakes. Does not work with the DV+ Diverter Valve or Diverter Valve spacers.
TURBO INLET PIPE FEATURES
Greatly improves air-flow to turbocharger
Constant high-flow inner diameter
Easy install, no modifications necessary
Long life cast aluminum alloy
In-house CNC machined for perfect fitment
No leak o ring seal to turbocharger
Outflows stock inlet by 110CFM
IS YOUR STOCK INLET ROBBING POWER?
The factory installed plastic turbo inlet found installed on your VW or Audi Gen 3 1.8T or 2.0T TSI engine is adequate enough for stock cars with factory hardware and ECU calibrations. However, the necked down design becomes a major flow restriction when ran with power upgrades such as cold air intakes, intercoolers, downpipes, and ECU upgrades.
UPGRADE YOUR TURBO INLET PIPE
The IE Turbo Inlet Pipe helps you to get the most out of your IS38 or IS20 turbo and power upgrades by removing the factory flow restriction. The cast aluminum design allows for a constant diameter elbow increasing efficiency from the intake to the turbo without the bottleneck design of the factory unit.

IE's Y-Pipe Adapter Kit is used to adapt either your IE Downpipe to a stock catback or your IE Catback to a stock downpipe. If you are using either of our exhaust components with a stock counterpart, this Y-Pipe Kit includes everything needed to make it an easy bolt-on solution.
CAST CONSTRUCTION
Using specialized 3D scanners and software, IE engineers can design odd shapes and sizes to maximize flow and conform into tight spaces without any sacrifices. These shapes can not be manufactured reliably from traditional piping, so we use a high quality stainless steel casting to realize the design. This makes for an incredibly high quality part that will not restrict power and will create a perfect fit every time.
IE cone filters are specifically designed for high-flow and perfect fitment to the integrated velocity stack found on most IE cold air intake kits. This is a dry filter that can be oiled, however, we do not recommend air filter oiling on turbocharged or forced induction vehicles. The filter can be cleaned and re-used many times. If you find it difficult to clean your filter or find it severy stained, it may be time to replace the filter element. This is a direct replacement filter ready to keep your car on the road and performing at its best. Includes new filter clamp.
The IE Audi B9 A4 & A5 2.0T Cold Air Intake is the perfect addition to any engine bay. Give your Audi added horsepower, torque, snappier throttle response, and an aggressive sound. Typical peak gains from our CAI are roughly 10-20 Horsepower and Torque.

INCREASED AIR FLOW
This Intake delivers an impressive flow increase to feed your turbo. More cold air flow means more power; especially during the hot summer months. Ditch your stock restrictive airbox for the IE intake System.
DESIGN DETAILS
IE engineers set out to produce the highest performing cold air intake that looks great and fits like a factory installed part in your A4. The latest in computer design and 3D scanning technology were employed during the development process for a perfect fit and maximum performance. The final product resulted in the greatest performing and best-looking intake available.
HIGH-FLOW VELOCITY STACK
Delivering cold air to your engine is a must for making power. The velocity stack efficiently channels air as quickly as possible into the intake system. The velocity also functions as a solid mount for the air filter which means no intake pipes rattling on heat shields.
CUSTOM HEAT SHIELD
IE uses a three piece heat shield which performs and looks great. It effectively channels cold air from the front of the car to the massive performance filter. Furthermore, it eliminates the induction of hot air found in other locations of the engine bay. A second heat shield is mounted above the turbocharger to further protect against power robbing heat off the exhaust and turbo.
PERFECT FITMENT
This Intake fits B9 Audi A4 and A5 without any modification or installation hassles. The install process is simple and can be done quickly with basic tools. The fact that IE intake utilizes the factory airbox mounts ensures a perfect and hassle free fit. Additionally, the stock rubber mounts allow for engine movement which keeps intake components from getting damaged.
CLASSY AND CLEAN APPEARANCE
Wrinkle black powder coated velocity stack and heat shields result in a sleek and sporty appearance in any engine bay. As a final touch, all IE heat shields are finished with a classy, laser etched, stainless steel IE logo badge.
