TNEER Valvetronic Exhaust System for Porsche 718 Boxster / Cayman 2017-2025

The Porsche 718 Boxster and Cayman share a mid-engine platform built around a 2.0-litre and 2.5-litre turbocharged flat-four across their respective specifications, producing between 300 and 365 horsepower depending on variant. The transition from the naturally aspirated flat-six of the previous generation to the turbocharged flat-four was one of the more discussed engineering decisions in recent Porsche history, and the exhaust system is a primary contributor to how the 718's acoustic character is perceived relative to its predecessor. On a forced-induction flat-four mid-engine platform, back pressure management downstream of the turbocharger outlet and mid-system flow geometry are the defining exhaust engineering variables. TNEER engineers this valvetronic system specifically for the 718 Boxster and Cayman, with mid pipe routing, mounting geometry, and system architecture developed to the exact mid-engine chassis layout shared by both body configurations across the full 2017-2025 production range.

Each section is formed from single-piece high-grade stainless-steel tubing using robotic pipe bending technology, producing continuous tube geometry throughout the system without the weld joints and flow disruptions of multi-segment construction. The mid pipe addresses the exhaust path between the turbocharger outlet and the valvetronic muffler section, establishing the flow characteristics and back pressure profile that define the system's performance contribution at the mid-engine level. The system installs to all factory mounting locations on both the Boxster and Cayman across all variant specifications, requiring no structural modification and maintaining correct chassis alignment throughout.

The valvetronic mufflers are managed through the TACS, TNEER's proprietary App Control System, which gives the driver full manual authority over valve position through a dedicated application interface independent of driving mode or vehicle operating condition. For 718 owners, the TACS introduces on-demand acoustic control to a platform where the factory exhaust presents a fixed output regardless of throttle input or mode selection. Valves closed, the system maintains a composed tone appropriate for road use while presenting more of the turbocharged flat-four's character than the factory exhaust allows at any throttle position. Valves open through the TACS, the full acoustic output of the 718's flat-four is unobstructed and responds directly to throttle input and engine speed. On a mid-engine sports car platform where the exhaust exits directly behind the cabin, the distinction between valves closed and valves open is particularly immediate and visceral.

Two tip configurations are available to complete the system at the rear fascia. The dual silver tips provide a clean, high polish finish consistent with the 718's precise, purposeful aesthetic. The carbon fiber tips present an alternative for owners whose build direction calls for exposed carbon at the rear, complementing both standard and modified 718 builds.

Optional Downpipe Configurations

For owners who want to address the primary restriction point in the exhaust path, TNEER offers two downpipe specifications that deliver meaningful performance and acoustic improvement beyond what the valvetronic muffler system alone provides.

The race downpipes remove the factory catalytic converters immediately downstream of the turbocharger outlet, where back pressure reduction has the most direct effect on turbine behavior, spool characteristics, and mid-range torque delivery. On a turbocharged flat-four mid-engine platform, the relationship between downstream restriction and turbocharger efficiency is immediate and measurable at every point in the rev range. These components are intended for closed course and off-road use.
The 200-cell sport downpipes retain a high-flow catalytic substrate in place of the factory units, reducing restriction significantly while maintaining a level of emissions compliance appropriate for street-driven builds. For 718 Boxster and Cayman owners who require a balance between full-system performance and daily usability, the 200-cell specification delivers a substantive upgrade within a practical operating profile.

All downpipe components are fabricated from high-grade stainless steel and engineered to the same fitment standard as the remainder of the system.

About TNEER:

TNEER is built around a single engineering conviction: the exhaust system is not a peripheral component. It is the primary interface between the engine and the driver's experience of it. Every system TNEER produces is developed to bring out the true voice of the engine it is built for, improving exhaust flow and delivering a distinct tone that is mechanical, raw, and directly connected to the character of the car.

The manufacturing process that defines TNEER's fitment standard is their high-tech robotic pipe bending technology. Rather than fabricating exhaust routing from multiple welded sections, TNEER forms each tube from a single continuous piece, bending high-grade material to navigate the spatial constraints of each specific engine bay without the diameter reductions, flow disruptions, and structural inconsistencies that welded multi-piece construction introduces. The result is an exhaust system with continuous tube geometry, perfect fitment to the platform it is built for, and no compromises in the routing that precision bending makes unnecessary.

For enthusiasts who regard sound and performance as inseparable elements of the driving experience, TNEER engineers each system to deliver both from the first throttle input.

Note:

Downpipes are not CARB certified and may not be legal for use on emissions controlled vehicles; intended for off road use only.
ECU tuning may be required due to removal of factory catalytic converters.

SHIPPING AND DAMAGE-

For items shipped by Creative Mods from our warehouse:

Most products leaving the Creative Mods warehouse go through careful inspection before shipping. Some items marked Do Not Repack (DNR) are sent in their original packaging and are not inspected internally. In many cases, our logistics team reinforces the manufacturer’s packaging to provide extra protection and reduce the chance of damage during transit.

Upon delivery, it is the customer’s responsibility to thoroughly inspect all items immediately, regardless of the condition of the external packaging. If there is any visible damage to the box or contents, you must photograph the damage and clearly notate it on the delivery receipt prior to signing. If you are unable to properly notate damage at the time of delivery, you must refuse the shipment. Once a package is signed for as “undamaged”, all rights to file a freight damage claim are forfeited, and Creative Mods will not be able to assist further.

All shipments are insured up to the stated value of the item(s); we cannot insure packages for more than their declared value. Any damage claim must be reported to Creative Mods in writing within 24 hours of delivery. After this period, claims, reorders, or refunds related to shipping damage cannot be processed. While we cannot guarantee the outcome of any claim, Creative Mods will support you to the fullest extent possible throughout the claims process.

For items shipped directly from manufacturers or third-party distributors:

If your order ships directly from a manufacturer or distributor, Creative Mods does not handle the packaging, shipping, or delivery. We also do not control their damage claim process. If there is a problem with your shipment, we will provide reasonable assistance should a shipping issue arise.

We strongly recommend that you follow the same inspection procedures outlined above when receiving third-party shipments. By placing your order, you acknowledge and agree to comply with all shipping and damage claim procedures required by the third-party shipper. If you would like additional information about third-party shipping insurance or procedures, please request these details prior to finalizing your order.

SHIPPING AND ORDER DELIVERY INFORMATION-

Items that are in stock within the United States whether housed at Creative Mods warehouse or at a supplier's facility are generally delivered within 7 to 10 business days for domestic orders. Special order items sourced from overseas may require significantly more time, depending on the manufacturer’s production schedule and international shipping logistics.

As a courtesy, Creative Mods provides estimated delivery windows based on our experience with manufacturers and their current shipping schedules. These estimates are meant to give you a general idea of lead times. Actual timelines can vary, depending on product availability and complexity, orders may take anywhere from 2 weeks to over 30 weeks.

Once manufactured, items are shipped to an international logistics hub and consolidated for ocean freight transport. Transit times can be between four to six weeks: approximately one week for local documentation and customs clearance, three-four weeks at sea, and one week for U.S. customs processing. Port congestion, customs delays, and carrier backlogs may further affect timelines and are entirely outside of our control.

Given the number of variables involved, all delivery timeframes are non-binding estimates and do not constitute a guaranteed delivery window. While we make every effort to provide accurate and conservative ETAs and often deliver faster than estimated, Creative Mods does not guarantee delivery dates for any special-order items.

By placing an order, you acknowledge that delivery times are estimates only and are subject to change. Orders cannot be canceled, changed, or refunded because of delays caused by manufacturing or shipping issues outside of Creative Mods’ control. Any ETA provided is for reference only and based on past experiences and feedback from manufacturers

EXTENDED STORAGE FOR ORDERS / ABANDONMENT POLICY-

When an order arrives at the Creative Mods warehouse and is ready to ship, we reach out to the customer to set up delivery. We provide up to 30 days of free storage, so customers have time to plan. After that, storage fees will be applied, and we will notify the customer before billing. Customers are still responsible for making sure their products are received within that timeframe.

Storage fees are assessed as follows (per calendar month):

$85 per larger sized boxes (bumpers, body kits, etc.)

$45 per medium sized box (hoods, exhaust, etc.)

$25 per smaller sized box

If items remain in storage for over a year, or if the storage fees add up to more than the value of the items, Creative Mods may take ownership of those items to cover the balance owed, unless other payment arrangements are agreed upon. Otherwise, storage fees will continue to build and will still be the customer’s responsibility. All parts remain the property of Creative Mods until paid for in full.

Order cancellations must be submitted in writing and approved by a manager at Creative Mods within 24 hours of order placement. Cancellations are granted at our sole discretion and are typically not permitted for special order or made to order items once procurement has begun.

Please note that some product images may include optional components, accessories, or finishing (e.g., paint) for illustrative purposes only, and may not reflect the exact specifications of the item being sold. If you have questions or need clarification, we encourage you to contact us prior to placing your order.

Sometimes pricing, shipping, or tax details on the site may not be calculated correctly. If that happens, Creative Mods will notify you prior to processing your payment. While we make every effort to ensure accuracy, we are not liable for such errors. If an error cannot be reasonably reconciled, Creative Mods reserves the right to cancel the order and issue a full refund.
