TNEER Valvetronic Exhaust System for BMW i8 2014-2020

The BMW i8 is built around a mid-mounted 1.5-litre twin-turbocharged three-cylinder petrol engine producing 231 horsepower, combined with an electric front axle motor for a combined system output of 357 horsepower in the standard configuration and 369 horsepower in the i8 Roadster. The i8's carbon fiber reinforced plastic passenger cell, aluminum chassis, and plug-in hybrid drivetrain represent a fundamentally different engineering philosophy from any other performance car in BMW's lineup, with the three-cylinder petrol engine's exhaust system operating within the specific packaging constraints of the mid-engine hybrid architecture. The i8's rear mid-engine layout, hybrid battery positioning, and carbon fiber body structure create exhaust routing requirements specific to this platform that differ from any conventional BMW application. TNEER engineers this valvetronic system specifically for the i8, with tube routing and mounting geometry developed to the exact mid-engine hybrid chassis layout of the platform.

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. On a turbocharged three-cylinder mid-engine platform where packaging constraints are among the most demanding of any production car, precise tube routing without multi-segment welded construction is a prerequisite for correct fitment. The system installs to all factory mounting locations, requiring no structural modification and maintaining correct chassis alignment throughout.

The ECU-controlled valvetronic rear mufflers manage acoustic output through the i8's existing vehicle architecture without secondary controllers or aftermarket modules as standard. For owners who want independent manual authority over valve position beyond what the vehicle's ECU architecture provides, TNEER offers the TACS as an optional addition. The TACS allows full manual valve control through a dedicated application interface at any time regardless of driving mode or vehicle operating condition.

Valves closed, the system maintains a composed tone appropriate for the i8's road use and hybrid operating profile while presenting more of the turbocharged three-cylinder's character than the factory exhaust allows at any throttle position. Valves open, the full acoustic output of the i8's petrol engine is unobstructed and responds directly to throttle input and engine speed. On a platform where the factory exhaust is specifically calibrated to manage the three-cylinder's acoustic character within the i8's design ethos, the distinction with valves open is immediately apparent and specific to this engine in this car.

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 throttle response. On a forced-induction three-cylinder platform, the relationship between downstream restriction and turbocharger efficiency is immediate and measurable across the full operating 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 i8 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 consistent with the i8's hybrid use character.

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