How much does an aftermarket exhaust kit cost?

It depends. For high-quality systems designed for optimal performance, like the ones offered by Integrated Engineering, prices can range from several hundred to a few thousand dollars or more.

How much horsepower will a performance exhaust add?

The horsepower gain from installing a performance exhaust system can vary, but it's not uncommon to see increases of 5-20 horsepower, depending on the vehicle and the exhaust system's design.

How does exhaust backpressure affect engine performance, and how do upgraded exhaust systems help?

Backpressure is a form of resistance against the flow of exhaust gases out of the engine. Some level of backpressure is necessary for optimal engine performance. Too much, on the other hand, negatively affects performance. Exhaust system kits are designed to minimize unnecessary levels of backpressure, thereby enhancing the engine's ability to “breathe” and ultimately resulting in performance gains.

Do I really need to upgrade my exhaust engineering?

No. But upgrading your stock exhaust parts with one of IE’s exhaust kits has several benefits, including: Exhaust performance and efficiency improvements. Increased horsepower and torque. A more aggressive exhaust note

What is the difference between cat-back, axle-back, and turbo-back exhaust systems, and which one should I choose?

Cat-back exhaust systems replace the stock exhaust components from the catalytic converter to the exhaust tips, improving flow and sound without altering emissions. Axle-back exhaust systems replace parts from the rear axle to the exhaust tips, offering a more modest upgrade primarily affecting sound. Turbo-back exhaust systems (for turbocharged engines) replace everything from the turbo's outlet to the exhaust tips, offering the most significant performance improvements. Note: these types of exhaust systems often require additional tuning for both performance and emissions reasons.

How does the design of the exhaust tips influence the exhaust note and vehicle aesthetics?

The design of an aftermarket exhaust changes the look of your vehicle’s rear, making it sportier. But the design may also influence the exhaust note slightly too. For instance, larger tips can amplify the exhaust note, and different shapes can alter the timbre/tone.

DESIGN DETAILS

BOLD, REFINED, ENRICHED

The popular 2015-2020 VW Golf R and Audi S3 is begging to be unleashed with the precision-engineered iE Catback Exhaust System. This bolt-on upgrade delivers a unique deep rumble at low revs and an aggressive roar at high RPMs. Our proprietary DroneTrap technology eliminates unwanted drone, leaving only the perfect exhaust rumble. The factory valve electronics integrate seamlessly, giving you full control to switch between subtle and rowdy modes. Finished with quad 4” slash-cut tips for true motorsport style.

OVERSIZED QUAD TIPS

MAKE A STATEMENT

Make your Golf R or S3 stand out from the crowd with our quad oversized 4" exhaust tips. The aggressive slash-cut design and sleek brushed finish deliver a distinctive motorsport look bound to turn heads. Depth adjustability allows you to customize the tips to match your unique style.

iE's advanced DroneTrap technology captures the pulse waves responsible for the 2.0T engine's exhaust note and draws them into a mathematically tuned resonator. The internal port is engineered to resonate these waves against each other in a process that selectively cancels out those responsible for annoying drones. The remaining waves produce the deep and enriched exhaust acoustics enthusiasts love.

BUILT TO ENDURE

QUALITY IS IN THE DETAILS

iE’s catback exhaust is built for sound, durability, and reliability. Made from mandrel-bent T304L stainless steel, it resists corrosion, with hand TIG-welded joints ensuring lasting strength. A stamped multi-wall muffler prevents warping, while reinforced hangers keep everything securely mounted. Bridged piping boosts strength and disperses weight to reduce stress and vibration. Inspired by high-end OE designs, wide-width stretch clamps keep every connection tight and leak-free.

YOUR STEREO IS OBSOLETE

SOUND CONTROL

SEAMLESS FUNCTIONALITY

Control your exhaust volume through the factory drive select controls from your MMI system. Select comfort to drive around your suburb like a civilized neighbor, or trigger Sport/Dynamic mode to release that boosted roar.

EXHAUST VALVES

REFINED TO ROWDY

In Comfort/Normal mode, the valves stay closed, routing all exhaust through the center-mounted muffler to reduce volume while keeping a sporty tone. Switch to Sport/Dynamic mode to open the valves, bypassing the muffler through twin 2.5" pipes for a loud, performance rumble.
