BMW M3 G80 / M4 G82 / M2 G87 Valvetronic Catback Single Mid-Pipe Titanium Exhaust System

Engineered for BMW M3 G80, M4 G82, and M2 G87 owners, this Valvetronic Catback Single Mid-Pipe Titanium Exhaust System ships with its own electronic control box and wireless remote — valve management is integrated during installation and afterward operated via the included remote. Manufactured in Europe and quality-controlled by BYC Performance, this system bolts directly to the stock mid-pipe v-band.

The Grade 5 titanium body is noticeably lighter than a stainless catback and develops a premium natural heat-tint finish. Single mid-pipe geometry provides a clean flow path paired with the characteristic sharp metallic note of titanium. 90 mm twin exit tips are customer-selectable in Glossy Black Stainless, Polished Stainless, Matte Carbon Fiber, or Glossy Carbon Fiber finishes.

Titanium vs. Stainless Steel — This Is Titanium

This product is the Grade 5 titanium variant:

• Grade 5 Titanium (this product): noticeably lighter, sharper metallic note, natural heat-tint, premium aesthetic
• T304 Stainless Steel: Deeper sound tone, cost-effective, durable
• For maximum weight reduction and premium aesthetics: titanium preferred
• This product is the performance-and-aesthetic-focused titanium variant

Single, Double, and Equal-Length Mid-Pipes — The Difference

Single, double, and equal-length mid-pipe configurations sit at the same price tier and offer different sound and flow characters — there is no price difference; the choice is entirely about the sound you want:

• Single Mid-Pipe — this product: Clean flow path, tonal sound character. Pairs with titanium for a sharp metallic note.
• Double Mid-Pipe: Twin parallel flow paths, more aggressive and fuller sound character.
• Equal-Length: High-RPM pulse synchronization, cleanest note and a marginal performance edge.

Installation Notes

Catback exhaust replacement requires lift access and professional installation. General procedure:

1. Lift the vehicle and loosen rear bumper underbody screws.
2. Release the stock catback mid-pipe v-band clamp.
3. Replace OEM exhaust hangers (rubber isolators) if worn.
4. Mount the included electronic control box in a suitable location and connect the valve actuator wiring.
5. Hang the new titanium catback on hanger points and torque the v-band clamp (10 Nm — titanium spec).
6. Confirm the exit tips are centered in the bumper cutout.
7. Pair the wireless remote and test valve open/close operation.

Care & Maintenance

Titanium is naturally corrosion-resistant. The heat-tint develops during the first track-temperature cycles and intensifies over time — avoid aggressive chemicals and wipe with a soft cloth. If you selected carbon fiber tips, use a carbon-safe cleaner. Re-check bolt torque after first 500 km. Titanium has no protective coating, so avoid oil and fingerprints on the visible surface.

FAQ

How is the exhaust valve controlled?
Via the included electronic control box and wireless remote. The control box is mounted in a suitable location during exhaust installation; you then open and close the valve using the supplied remote.

How is the titanium sound different?
Sharper, more metallic note vs. stainless steel, with a brighter tonal character — especially at high RPM.

How loud is it?
Calm and daily-friendly with the valve closed, noticeably fuller and more aggressive with the valve open. The titanium tonal character is cleaner than the MP stainless variant.

Is it TÜV / E-mark approved?
The catback section does not include a catalyst, so emissions are unchanged.

Welded or direct bolt-on?
Direct bolt-on. V-band clamp + hanger system, no welding required.

Does it fit both M3 G80 and M4 G82?
Yes. M3 G80 Sedan, M4 G82 Coupé, and M4 G83 Convertible share the same rear exhaust outlet geometry.

Does it fit the M2 G87?
Yes. The shared S58 engine platform makes this fully compatible with the BMW M2 G87 Coupe (2023+).

Does it fit the M4 G83 Convertible?
Yes, the BMW M4 G83 Convertible (Cabriolet) is fully compatible.
