BMW M3 E92: enhancing the naturally aspirated S65 V8, the complete exhaust system guide

The S65: eight cylinders, 8,400 rpm, zero turbos

The 4.0L S65 produces 420 hp without any forced induction: individual throttle bodies, dizzying revs and a throttle response that modern turbo engines cannot reproduce. Its natural sound is exceptional, but the heavy, heavily muffled factory exhaust holds some of it back, especially in the mid-range where the V8 builds its crescendo.

On a naturally aspirated engine, freeing up the exhaust directly changes how the car feels: the crescendo becomes continuous from idle to the redline, and every gear becomes an event. That is exactly what the Rog exhaust brings to the E92, with valves to spare your daily commute and your neighbors.

How the exhaust on your BMW M3 E90 / E92 / E93 is put together

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

Your BMW M3 E90 / E92 / E93 in figures

An exhaust system is judged first by ear and on the scales. The extra horsepower comes from an ECU remap.

Published factory and Stage 2 figures.

The Rog exhaust works with or without an ECU remap. To get the full potential out of your BMW M3 E90 / E92 / E93, we recommend taking it to an approved tuning center afterwards.

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 safe bet: strong, corrosion-proof, with a full, rounded sound. The best value for money.

   Titanium

   Weight

   Around 40% lighter

   Sound

   Metallic, crystal-clear

   It makes the exhaust around 40% lighter for the same design. Its note is more metallic and clearer higher up the rev range, and its finish ranges from brushed to blued.

   No worries on durability: 304 stainless steel shrugs off winter road salt 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 BMW M3 E90 / E92 / E93, with the catalytic converter. Each option is placed on our sound scale of 0 to 10, valves open, with the factory exhaust at 3.

   Cat-back only

   Included

   7/10

   Factory emissions control

   The factory front section stays in place. It is already a complete transformation, and the choice of many of our customers.

   200-cell sports catalytic converter

   8/10

   Road use and inspection

   More flow, emissions control retained: the right option for road use.

   100-cell sports catalytic converter

   9/10

   Inspection: depends on local rules

   More open than the 200-cell: the sound hardens at high revs and emissions control is reduced.

   Decat

   10/10

   Track use

   Flow with no filter at all: the rawest sound and the sharpest response.

   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.

3. 3

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

   Two ways to control the valves on your BMW M3 E90 / E92 / E93.

   Rog remote

   

   A discreet control unit in the trunk and a two-button remote: you open and close whenever you like, independently of the drive modes. For fitting, we support you by email.

   Factory control

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

   For vehicles fitted with factory valves: the exhaust connects to their control and the drive modes stay in charge, with no extra control unit.

   At 130 km/h, many sports exhausts drone. Here, with the valves closed, the exhaust flows through the muffler and stays composed when cruising; open, it makes itself heard when you choose. More about exhaust drone.

   Step 4 of 4: Tips: the visual signature

   Match the tips to the style of your BMW M3 E90 / E92 / E93, understated or bold. A particular finish in mind? Send us a photo and we will look at it together.

   • Black
   • Carbon

The Rog sound signature on the S65

The S65 shares its DNA with the V10 in the M5 E60: a high-pitched, furious voice that builds with the revs. Our exhaust reduces back pressure and removes unnecessary filtering to unleash that character: raspy and present in the mid-range, screaming beyond 7,000 rpm, with the mechanical fury only the great naturally aspirated engines possess. With the valves closed, the E92 remains usable every day without fatigue.

On this model, two characters at the same price: the straight pipe for the raw sound of your engine, unfiltered, or the resonator for a rounder and slightly softer voice. Either way, the exhaust stays fully sporty.
