IE CATBACK & DOWNPIPE
ENGINEERED TO PERFORM
Most aftermarket catback systems for the RS3 are designed to mimic the factory twin pipe setup making it easy to connect to the downpipe. This was fine for factory or mildly tuned setups, however the split pipe system can not keep up with the flow demands of aggressively tuned engines and big turbo setups, causing power loss. The IE catback center pipe is a massive 3.5" straight-through pipe that splits to dual 3" pipes out the back with the valves open. This is enough flow to power even the largest turbo setups.
CLASSY & UNIQUE
- EXOTIC TIP DESIGN
- Whats the point of a larger exhaust that looks stock? Truly stand out from the crowd with a set of unique stylized exhaust tips. These custom shaped over-sized tips fill up the factory exhaust cut outs and update it with a look that belongs under a modern super car.
- AVAILABLE IN POLISHED OR SATIN BLACK FINISH
- Available in your choice of a brilliant polished finish or an optional satin black to match your black optics package.
- FIT TO YOUR TASTE
- The exhaust tips are fully adjustable up, down, in in/out. The final look of how they sit is up to you! Choose a flush install or a more aggressive look past the bumper.

EASY SOUND CONTROL

Simply select comfort to drive around your suburb like a civilized neighbor -or select dynamic to blow their ears out with that 5 cylinder furry.
*Retains dynamic, comfort, individual, and auto modes.
OPEN EXHAUST VALVES
With the exhaust valves in their open setting (dynamic mode) the exhaust flows from the main 3.5" pipe into dual 3" pipes and directly out the back unrestricted. This setting offers both the highest flow and loudest sound possible from your exhaust.
CLOSED EXHAUST VALVES
Cruising in comfort mode closes the dual exhaust valves forcing the exhaust to flow from the single 3.5" center pipe into the muffler and out twin 2.5" pipes. This keep the sporty exhaust note, but with a dramatically reduced stock-like noise level.
PRECISION FIT
IE engineers use 3D scanning tools to create a digital duplicate of the vehicle's under body. This provides an incredibly high resolution environment to reverse engineer and rapid prototype a performance exhaust that not only takes advantage of every millimetre of available room, but also results in a perfect fit and easy installation.
SUPERB CRAFTSMANSHIP
Each IE catback is manufactured from the highest standard 304L stainless steel, mandrel bent, and TIG welded by hand all using precise fixtures and tooling. We take great pride in knowing your new exhaust is built to last a lifetime.

The exhaust tips feature horizontal, vertical, and depth adjustments so you can perfect them exactly as you wish. Not only will your exhaust sound and perform amazing, it will look the part as well.

Exceeds performance expectations of OEM fluids
Size: 5 Quart Jug
You know I didn't think it would work as well I've heard all these horror stories but you know what this works better than the factory CVT fluid this stuff is great this is amazing be very careful to get your levels correct that goes without saying with any transmission but once you do that this fluid is amazing I have a better performance than when I had the new transmission I serve my CvT 35 to 40,000 miles I'm using it in a 2018 Mitsubishi outlander base model and I'm also running Yokohama geolander 015s on it. If you worry about tires for you Mitsubishi or any vehicle. I'm going to say you'll call when you lander whether it's a car or crossover or an SUV this tire is amazing it's best all around tire and your rain traction is phenomenal

Good Stuff!! All low speed shudder is gone.
Size: 5 Quart Jug
I have a 2020 Nissan Altima SL 2.5l and Nissan is VERY specific about using ONLY NS3 transmission fluid. There are only a couple NS3 transmission fluid manufacturers...Nissan NS3 (Manufactured by Idemitsu), Idemitsu (a little cheaper than Nissan dealer), Triax, and Mannol (works good too).
Seeing as Nissan is still using Jatco CVT transmissions which are known to be very troublesome, and very expensive to replace I wouldn't try any of the so-called "universal" transmission fluids just to save $50 and end up replacing a $6000 transmission.
The Triax fluid seems to work very good in my car. I don't feel the shutter that I normally feel when driving slow and need to accelerate. The shudder is completely gone and operating smooth.
The old fluid had 50k miles and it was very dirty but didn't smell burnt.
I ended up doing 2 - 3 1/2 quart changes with 200 miles between the first and second change.
I plan on doing another 3.5/4 quart change every 15k miles since there is no way to completely drain the 7.4 quarts of transmission fluid. The first change, only 3.5 quarts drained from the pan.

Quality fluid for half cost in Mini CVT.
Size: 5 Quart Jug
Used in the cvt transmission in my 06 mini cooper. The fluid requirements recommended by BMW are met with this fluid. Fluid improved shifting and performance at half the cost of traditional BMW OEM fluid.

This CVT Fluid worked perfectly in a 2018 Chevrolet Spark.
Size: 5 Quart Jug
This fluid is fantastic. I bought a 2018 Chevrolet Spark with 30K miles and had a bad transmission shudder. Drained the transmission, cleaned-out the pan, and replaced the filters. Old fluid was black and this is a clear green. I loved the jug as it had a pop-up spout that was small and easy to pour, and the jug has a side handle. Transmission works great and the shudder is gone. I plan to change the filters and fluid again after 1K miles. This fluid is well worth the money!
