    DESCRIPTION

    Turner Motorsports new cat-back exhaust is designed to take out restrictions, maximize flow and give your B58 a signature exhaust note that will excite you on every drive from the time it is installed. From the factory the exhaust comes equipped with a a center muffler, rear section resonator and a bulky muffler. The combination of 3 muffler/resonators do its best to quiet down the B58 and as a side effect, increase backpressure. With all of those stop gates how do you expect to get the maximum performance out of your vehicle, you simply cannot do so. Lucky for Turner you no longer have to deal with the quiet and limiting factory exhaust.

    If you still have the factory exhaust fitted to your B58, you don't know what your missing. Free up lost performance with a new full cat-back exhaust complete with factory valve control!

    To create a cat-back exhaust for this incredible engine the changes happen right after the downpipe. Turner replaced the factory oval pipe with 3.0" T304 stainless steel piping. The true 3.0" exhaust makes its way through the center and rear of the car without the center muffler or resonator to keep flow to a maximum! With smooth mandrel bent transitions the exhaust passes perfectly under the rear subframe for a factory-like fit. Positioned in the rear of the car is their signature B58 muffler with beautiful inlet and outlet piping that creates the perfect exhaust tuning. Featuring relief cut slip joints and fabricated sheet metal brackets the exhaust can be fully adjusted and mounted seamlessly in the factory locations. Dual 4.0" exhaust tips are optioned to fill out the open space in the rear diffuser and complete the rear profile of the vehicle.

    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.
