    DESCRIPTION

    Looking to add an aggressive appearance upgrade while enhancing the exhaust note on your MK7 Jetta 1.4T? Our ECS Tuning In-House Designed & Engineered Quad Tip Axle-Back Exhaust System gives your VW the enhanced performance upgrade you've been looking for! Our Axle-Back system locates four of our ECS Tuning Swivel Exhaust Tips within our ECS Rear Diffuser for a sporty Euro appearance upgrade that's found nowhere else! Not only does our exhaust system add a German sports car look, but we bump up the volume by deleting the OEM muffler, which adds a smooth exhaust note that allows you to enhance your driving experience with your 1.4 liter turbocharged engine!

    Our exhaust system is made from high quality brushed T304 stainless steel with Tig-welded joints for an exceptional look and durability. Our exhaust connects to your stock exhaust system with 1 simple cut and then routes spent exhaust gases to a pair of our CNC-mandrel bent 57mm tailpipes before splitting into a quad-pack of slant-cut 3.5" swivel exhaust tips. Extremely durable, stainless steel, barbed exhaust hangers are Tig-welded in place and an additional exhaust hanger is included for the passenger's side tailpipe.

    Our included ECS Tuning Quad Tip Rear Diffuser features a deep profile, an aggressive blade design and exposed tip openings to house our ECS Tuning 3.5" swivel exhaust tips. The diffuser was designed and engineered in-house to add an aggressive appearance upgrade while supporting our quad tip exhaust system.

    ** NOTE: The rear valance is only serviceable on R-Line and SEL Premium models, other trim levels will need to convert to the aforementioned trim model rear bumper to use our diffuser (see ES#4040412 instead).

    Part Design

    • Rear Diffuser
    • — Designed and engineered in-house using state of the art 3D laser scanning and CAD technology for precision fitment. Mimics the design of our carbon fiber version as closely as possible for similar styling.
    • — Featured on Jamie Orr's MK7 Jetta 2018 SEMA build and tested on the Nürburgring and the Autobahn
    • — Made from lightweight, vacuum formed gloss black ABS polymer that is enhanced with UV-stabilizer
    • — CNC-Machined tabs for perfect engagement
    • — Mimics the lower section of the bumper & OE valance lines to accentuate OEM features
    • — Utilizes the dead space behind the OE valance to simulate a functional diffuser with great depth
    • — Outer blades blend into quad exhaust housings that accommodate up to 3.5" OD exhaust tips, on either side of the diffuser, and will work in tandem with our ECS Quad Tip Axle-Back Exhaust System or Borla Quad Tip Catback.
    • — Mounts to OE clip locations and OE holes on the outer edges of the bumper with our supplied, stainless and corrosive resistant zinc hardware.
    • — Includes a wrinkle black powdercoated, 5052 aluminum bracket to add rigid mounting to the center of the diffuser.
    • Axle-Back Exhaust System
    • — In-house designed and engineered using FARO ARM laser scanning technology for precise fitment
    • — T304 Stainless Steel Mandrel Bent, Brushed Tubing with 1.25mm wall thickness
    • — Dual 57mm Tailpipes with Tig-Welded connections
    • — Over double the cross sectional area to free up the restriction from the large, rear muffler
    • — Minor increase in weight over OEM muffler (ECS Axle-Back Exhaust - 23 lbs VS OEM Muffler - 18 lbs)
    • — T304 Stainless Steel 12mm barbed round stock exhaust hangers Tig-Welded in OE locations for precise fitment. An additional exhaust hanger with mounting bolt is included for the passenger-side tailpipe.
    • — Strategically placed slip joints provide the most adjustability to obtain perfect fitment

    WARRANTY

    Products are warrantied by their manufacturer. Eurosport Performance is an authorized reseller: every part we sell is covered by the manufacturer's own warranty, with its own terms and duration. Claims go through us, so you deal with Eurosport Performance rather than a form on the brand's site, but whether a claim is accepted is the manufacturer's decision.

    Manufacturer terms apply
    Duration and coverage are set by the brand and differ from one to the next: some cover one year, some a lifetime, some only the original purchaser. The brand's warranty page is the reference; ask us if you cannot find it.
    We file the claim for you
    Contact us with your order number, photos and a description of the issue. We open the claim with the manufacturer, follow it up, and arrange the repair, replacement or credit they approve. The manufacturer decides whether the claim is accepted.
    Fitment guarantee: North America only
    We guarantee fitment for vehicles sold in the North American market. Vehicles from other markets are out of scope; specifications differ, and it is the customer's responsibility to confirm compatibility before ordering.
    No warranty on tuning files
    ECU and TCU tunes and other software files are sold without warranty and are not returnable once delivered or flashed. Tuning can affect your vehicle's factory warranty; please read the brand's terms before purchasing.
    Proof of purchase
    Your Eurosport Performance order is the proof of purchase every manufacturer asks for. Keep the order confirmation; it is also in your account on the site and in the SPECD app.
    What is usually not covered
    Damage from improper installation, modification, abuse, racing or an incorrect application for the vehicle, and normal wear items such as pads, clutch discs and filters. Shipping and labour are covered only when the manufacturer's terms say so.
    Frequently asked questions
    How long is the warranty on this product?

    It is the manufacturer's warranty for that product. Where the brand publishes it, we note it in the description; otherwise contact us before ordering and we will confirm the exact terms with them.

    A part failed. What do I do?

    Stop using it if it is a safety-related part, then contact us with your order number, clear photos, and when and how the issue appeared. Do not return anything until we confirm the claim; manufacturers often require an inspection or an authorization number first.

    Who decides if my claim is accepted?

    The manufacturer. We prepare and submit the claim, provide the proof of purchase and push for a fair outcome, but acceptance, replacement or credit is their call under their terms. We pass their decision on to you as soon as we have it.

    How long does a claim take?

    It depends on the manufacturer. Simple cases are approved in days; claims that need the part inspected can take a few weeks. We keep you updated at each step and push when it drags.

    Is there a warranty on ECU or TCU tunes?

    No. Tuning files are software; once delivered or flashed they cannot be returned, and they carry no warranty from Eurosport Performance or, in most cases, from the tuner. Support for the tune itself (revisions, flashing questions) comes from the tuning brand under its own terms.

    My car is from outside North America. Is fitment guaranteed?

    No. Our fitment guarantee covers vehicles sold in the North American market only. European, Japanese and other market vehicles can differ in engines, electronics and dimensions, and a part listed for the North American model is not guaranteed to fit. If you order for one of these vehicles, confirming compatibility is your responsibility, and fitment issues on such vehicles are not covered by returns or warranty.

    Is installation covered?

    Labour is not covered unless the manufacturer's terms specifically include it. Having the part installed by a qualified shop protects your claim: improper installation is the most common reason a manufacturer declines.

    Is a warranty issue the same as a return?

    No. Returns cover unused parts you no longer want, under our refund policy. Warranty covers a part that fails in use, under the manufacturer's terms. If you are unsure which applies, contact us and we will point you to the right one; please do not open a bank dispute, as it pauses both processes.

    Questions about coverage before you buy? Email us with the product and your vehicle and we will confirm the manufacturer's terms.
