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.

IE Audi B9 A4 & A5 Cold Air Intake - Fits Cars With NO MAF ONLY
INCREASE POWER AND SOUND WITH A COLD AIR INTAKE
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.
POWER GAINS
The ram air design, velocity stack, and massive 55-inchfilter inlet help deliver the most HP possible from a cold intake system.
Expect peak gains of 10-20+HP/TQ on tuned engines.INCLUDED IN THE B9 IE CAI KIT
- IE Intake velocity stack & heatshield assembly
- IE Silicone turbo inlet pipe assembly
- IE 5” inlet performance air filter
- IE Turbo heat shield
- All necessary hardware (clamps, nuts, bolts, etc)
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.
EASY INSTALLATION

IE B9 A4 & A5 Performance Catted Downpipe
Description:
LEADING FEATURES
- Excellent power gains with matching Stage 2 Tune
- Cast sections ensure maximum flow
- Stainless steel and TIG welded for a gorgeous fit and finish
- True 76mm without necking down to OE sizing at CAT
- High flow 200 cell CAT for full power and reduced pollutants
- Tuned resonator keeps highway drone to a minimum
- Direct bolt-on fitment
The IE B9 A4 & A5 Catted Downpipe is engineered to completely reduce turbocharger back pressure and increase turbo spool required for the calibrations of a stage 2 ECU tune. The combination of a performance downpipe and ECU tune together unlocks the full performance potential of your stock turbocharger and engine, delivering 97 horsepower over stock. Get ready to experience addictive power gains across the entire RPM range and an aggressive exhaust growl you are bound to love.
ADVANCED SOUND TUNING
IE engineers elected to use a resonator in the B9 A4 & A5 exhaust. The result was a much better sounding exhaust overall. The factory cat back has a very unpleasant rasp when used with a downpipe which does not have a resonator. As IE engineers are true enthusiasts as well, it was very important that the exhaust also sounded great. Check out the video to hear stock vs. IE sound clips.
*All sound clips are on a Stage 2 vehicle with IE cold air intake and intercooler installed. Only the downpipe was changed, no modifications were made to the factory installed catback.
HIGH-FLOW CATALYST
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.
QUALITY CAST SECTIONS
Typical aftermarket downpipes use bends or cuts to form the shape of the downpipe; this allows the use of larger piping, but sacrifices flow and often times fitment. 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. To accomplish these shapes, sections of the dowpipe are cast manufactured from the digital models. The result is an incredibly high-quality performance unit with a perfect fit and beautiful finish.
