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.

UNLOCK STAGE 2 POWER:
Equipping your MK5 or MK6 2.0T engine with an IE catted downpipe delivers additional horsepower, torque, and responsiveness when coupled with a matching Stage 2 or K04 turbo upgrade ECU tune. These significant power gains are added through the entire RPM band by allowing the turbocharger to flow freely through the 3" downpipe, high-flow catalytic converter, and mid-pipe. Careful tuning of the added sound from freeing up exhaust flow rewards you with an aggressive exhaust growl every time you touch the accelerator while minimizing cabin drone.
All IE exhaust systems are designed in-house using state of the art digital scanning for a perfect fit and manufactured from 1.5mm thick wall 304 stainless steel offering a lifetime of performance and fun.
SOUND TUNING:
Give your car an aggressive motorsport sound that will keep you addicted to the throttle pedal without annoying exhaust drone. Engineered with thick-wall tubing and precise bends the downpipe opens up an unrestricted exhaust with a tuned sound without the "tinny" drone common on cheap catless downpipe options.
HIGH-FLOW CATALYTIC CONVERTER (CAT):
IE's performance downpipe for the MK5 & MK6 2.0T engines include a high-flow 200 cell per inch metal matrix catalyst (CAT) on the mid pipe section. This included CAT greatly reduces emissions output and unwanted offensive smells common on all catless systems, without losing horsepower! Have all the benefits of catless performance and none of the drawbacks with the IE high-flow CAT system
BOLT-ON INSTALLATION:
The IE downpipe replaces the majority of the factory exhaust from the turbocharger all the way back to the factory rear exhaust just before the axles. The 16mm turbo flange bolts to the stock or a K04 turbocharger. The downpipe section includes a new mount bracket and utilizes the factory mount points along with a tough interlock core flex section, this allows engine and chassis movement without stressing or cracking your downpipe. Easily connect the downpipe and catted mid-pipe using the simple and strong v-band connection. Finally, the mid pipe mounts to the stock rear exhaust with the included 3" to 60mm slip-fit sleeve, or easily adapt it to your cat-back exhaust of choice. In-house digitally scanned and designed for an exact fit and includes all hardware to make the install easy and straight forward.
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.
The following power result data was collected on our in-house Dynapack hub dyno. Dyno chart is as tested at 4500 feet altitude with SAE corrected numbers. Before and after results are direct back-to-back comparisons on a full bolt-on stage 2 B9 A4 2.0T engine. The only change made to the vehicle between testing is the swap from a stock intake with a new clean air filter to the IE Cold Air Intake Kit.

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.

YOUR BUILD DESERVES THE BEST
Feed your 2.0T TSI GTI, Jetta, GLI, CC, or A3 with a supply of cold air with this direct-fit high-flow cold air intake kit. This intake features a generously-sized inlet pipe that connects to the OE mass air flow (MAF) sensor. The MAF sensor receives high-velocity air fed directly from a 5" bellmouth. Our high-flow bellmouth is neatly housed in a heat shield, which separates the air filter from the hot under-hood air, allowing only cold air to be drawn into the turbo inlet directly from the front of the car.
STOCK-LIKE DIRECT FIT
This air intake kit provides all the necessary piping and couplers to plumb the intake system from the turbo to the MAF and then to the heat shield. The heat shield installs using the OE grommets for easy maintenance and reliable mounting with no rubbing or interference with other factory parts.
HIGH-FLOW VELOCITY STACK
The air intake utilizes a high-flow bellmouth behind the air filter to deliver as much air as possible. This bellmouth design increases the air velocity to the MAF and pulls cold air equally from all directions into the filter. This bellmouth is securely fastened to the heat shield as a clean pass-through providing a solid mount for the air filter and turbo inlet pipe. You have no worry about the intake pipe moving around and causing damage unlike other intake kits on the market, which simply clamp the filter onto the end of the inlet pipe or MAF. Furthermore, the bellmouth opening allows for a filter with a very large surface area that can support any horsepower goal. The same filter and bellmouth design have been tested to support over 500HP!
THERMAL BLOCKING HEAT SHIELD
The IE heat shield is designed to create a thermal barrier blocking all of the radiant heat from the engine bay. Only cold air from the front of the vehicle is drawn into the filter from the opening in the radiator support keeping air intake temperatures as cold as possible. This allows factory placement of the intake to be used without placing the filter lower in the vehicle where it can be subjected to engine harming road debris or fluid.
DO YOU NEED AN SAI KIT?
The MK5/MK6 2.0T TSI engine has two different engine codes. CBFA engine codes are equipped from the factory with a secondary air injection (SAI) pump that connects to the factory intake box. These engines require a small breather filter for this SAI line when installing an aftermarket intake. CCTA engine codes do not have this SAI pump and will not require this filter. Identify your engine code using the photos below, and add an SAI filter kit above if needed when ordering your intake.
EASY INSTALLATION
Installation is quick and easy to install with basic tools. The process should take around an hour for most enthusiasts.
