Lotus Emira: lighter, more vocal, the complete exhaust system guide

Your Lotus's engine: the Chapman philosophy applied to the exhaust

Your Emira follows Colin Chapman's doctrine: lightness above all. Every kilo counts, every sensation comes through unfiltered, and the engine, mounted right behind you, is an integral part of the experience. The factory exhaust is decent, but it remains an area where Lotus had to compromise with regulations: too much weight and too many mufflers, not enough character.

The Rog exhaust takes the doctrine all the way: lighter and freer, it amplifies what makes a Lotus a Lotus, the direct connection. The mid-mounted engine sings a few centimeters from your ears, and the valves keep the volume under control.

How the exhaust on your Lotus Emira V6 supercharged is put together

An exhaust system is best understood in two parts. Here is what each one does, and what Rog replaces.

Your Lotus Emira V6 supercharged in figures

On a modern car, an exhaust system first changes the voice, the breathing and the weight at the rear. Power, on the other hand, comes from an ECU remap.

Published factory figures.

Our exhaust systems work perfectly with or without an ECU remap. On your Lotus Emira V6 supercharged, however, we recommend one at an approved tuning center: it is what lets the engine deliver its full potential.

Let's be honest: on a Lotus, the exhaust's gain is measured as much in kilos as in horsepower, and that is a compliment. Breathing improves, the sound is transformed, and weight comes down. The supercharged versions also respond very well to an ECU remap at an approved tuning center.

Configuring your exhaust, step by step

4 choices, in the same order as the product page configurator.

1. 1

   Step 1 of 4: Material: stainless steel or titanium

   Titanium costs more than stainless steel; the price of each version is shown on the product page, in your currency.

   304 stainless steel

   Weight

   Baseline

   Sound

   Full and rounded

   The benchmark for high-end exhausts: tough, corrosion-proof, with a full, rounded sound. The choice of most of our customers.

   Titanium

   Weight

   Around 40% lighter

   Sound

   Metallic, crystal-clear

   Around 40% lighter than stainless steel for the same design, with a more metallic sound that turns crystal-clear at high revs. Its finish ranges from brushed to blued tints.

   Over time, both hold up: 304 stainless steel stands up to winter salt and damp, and titanium does not rust. Stainless steel or titanium: what really changes.

2. 2

   Step 2 of 4: Front section: manifolds and catalytic converter

   Optional: the manifolds on your Lotus Emira V6 supercharged, with their catalytic converter. Sound intensity is rated on our scale of 0 to 10, valves open; the factory exhaust scores 3.

   Cat-back only

   Included

   7/10

   Factory emissions control

   The factory catalytic converter stays in place. The starting point and, for many of our customers, more than enough.

   200-cell sports catalytic converter

   8/10

   Road use and inspection

   Emissions control is still very much there, and flow improves noticeably. The choice for everyday driving.

   100-cell sports catalytic converter

   9/10

   Inspection: depends on local rules

   Half as many cells: flow comes close to a decat and the sound gains real aggression at high revs.

   Decat

   10/10

   Track use

   No emissions control: maximum flow, raw sound, the sharpest revving.

   Sound intensity, on a scale of 0 to 10

   1. 10/10Decat manifolds + Rog cat-back
   2. 9/10100-cell sports catalytic converter + Rog cat-back
   3. 8/10200-cell sports catalytic converter + Rog cat-back
   4. 7/10Rog cat-back only, factory catalytic converter retained
   5. 3/10Factory exhaust, for comparison

   Valves open. With the valves closed, every configuration becomes discreet again.

   What about the engine warning light? With a sports cat, it can come on with some engines: the sensor placed after the catalytic converter measures a different level of emissions control from the original. It is not a mechanical failure, but a warning light should never be masked or cleared without dealing with its cause: the right answer is a catalytic converter suited to the engine, with a map by a tuner who takes it into account. The decat version, for track use only, almost always triggers it. If this happens to you, write to us and we will point you in the right direction. Passing vehicle inspection with a sports exhaust.

   Step 3 of 4: Valves: Rog remote or factory control

   Two ways to control the valves on your Lotus Emira V6 supercharged.

   Rog remote

   

   A small control unit fits in the trunk. Two buttons, open and closed: the valves respond at any moment, whatever the drive mode. Simple to fit, and we stay on hand throughout the installation.

   Factory control

   • Only for vehicles fitted with factory valves
   • Controlled by the drive modes

   If your vehicle is fitted with factory valves, the exhaust keeps their existing control. The drive modes decide, just as they did from the factory, with no added electronics.

   On the highway, with the valves closed, the gases pass through the muffler, designed for cruising: no drone at a steady speed. You open up when you feel like it, not when the highway decides for you. More about exhaust drone.

   Step 4 of 4: Tips: the visual signature

   Match the tips to the style of your Lotus Emira V6 supercharged, understated or bold. A particular finish in mind? Send us a photo and we will look at it together.

   • Chrome
   • Gloss black
   • Blued titanium

   

The Rog sound signature on your Lotus

The mid-mounted engine sings right behind you: our exhaust turns up the volume on that privilege. A freed-up timbre, total presence through the revs, crisp crackles on the overrun with the valves open, and a weight saving true to the Chapman doctrine. With the valves closed, journeys stay civilized.

What about the manufacturer's warranty on your Lotus Emira V6 supercharged? In Europe, a manufacturer cannot refuse warranty cover simply because a part from another brand has been fitted: it has to prove that the fault comes from that part. Our article on the manufacturer's warranty.
