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.

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!

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.

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!

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. 

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.

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.

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.

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.

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.

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.
