The Lotus Emira blends precision handling with exotic car presence, but like many modern performance vehicles, its factory exhaust system is held back by restrictive emissions equipment. Since late 2018, gasoline particulate filters (GPF/OPF) have become common in performance cars, significantly reducing sound output. While these filters are effective for emissions control, they often suppress the tone and character enthusiasts expect from a high-performance V6. Milltek Sport, a leader in performance exhaust engineering, offers a range of upgrades for the Lotus Emira that restore and amplify its aural personality without compromising build quality or fitment. Available through Bulletproof Automotive, these parts are engineered for enthusiasts who want their Emira to sound as good as it drives, with the confidence of ordering from a trusted supplier of premium performance parts.
At the core of the lineup is the Milltek Valved GPF-OPF-Back Exhaust System, engineered to counteract the sound-dampening effects of the particulate filter while enhancing exhaust flow. The system features a 76mm (3-inch) pipe diameter and includes valved connecting pipes, a rear silencer, and dual outlet pipes. Designed for the 3.5L supercharged V6, this setup integrates seamlessly with the Lotus Emira’s original tips and valve actuator. The valved design allows drivers to enjoy a more subdued tone when cruising, then unleash a deeper, more aggressive note at the touch of a button. While it’s not EC-approved, the precision engineering and factory-like fitment make it a compelling upgrade for drivers seeking both performance and flexibility.
For those seeking the most unfiltered exhaust experience, Milltek offers the Race OPF-GPF Pipe. This component replaces the factory particulate filter section entirely, optimizing exhaust flow and delivering a sharper, more aggressive tone that transforms the Emira’s character. Constructed with an 80mm (3.15-inch) diameter, it pairs perfectly with either the OE exhaust or Milltek’s GPF-OPF-back system. The result is a significant increase in volume and responsiveness, making it ideal for track use or drivers who want a raw, motorsport-inspired sound. As a motorsport-use-only part, it’s designed for those who prioritize performance and excitement over regulatory compliance.
To complete the package, Milltek’s Active Valve Controller offers ultimate flexibility in managing exhaust volume and tone. Designed for use with both OE and Milltek Sport exhaust systems on the Lotus Emira, the controller allows drivers to select from up to eight different sound files, with adjustable pitch, tone, and volume. Using Milltek’s dedicated iPhone or Android app, owners can create and save custom sound profiles, tailoring the exhaust note to suit every driving scenario. The kit includes a valve control system and two remotes, providing both in-car and handheld control. Easy to install and intuitive to use, it’s the perfect solution for those who want to control their Emira’s voice as precisely as its handling.
Each of these Milltek products is engineered to the highest standards, offering precision fitment, high-quality materials, and the kind of sound that elevates every drive. Whether you choose the versatile valved GPF-OPF-back system, the uncompromising Race OPF-GPF Pipe, or the customizable Active Valve Controller, you can unlock the full sonic potential of the Lotus Emira.
