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

Engineered for BMW M3 G80, M4 G82, and M2 G87 owners, this Valvetronic Catback Equal-Length 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 construction is noticeably lighter than the stainless counterpart and delivers a sharp metallic exhaust note; the equal-length mid-pipe geometry synchronizes post-turbine gas pulses for the cleanest high-RPM sound and a marginal performance edge. Across the S58's 473-543 hp (M3/M4) and 460 hp (M2 G87) output range, titanium's low thermal expansion provides long-term durability. 90 mm twin exit tips are customer-selectable in Polished Titanium, Blue Heat-Tinted Titanium, Matte Carbon Fiber, or Glossy Carbon Fiber finishes.

Key Features

• Included Electronic Control Box and Remote: System ships with its own valve control box and wireless remote.
• Grade 5 Titanium: Noticeably lighter than stainless, high strength-to-weight, natural heat-tint aesthetic.
• Equal-Length Mid-Pipe: Two parallel pipes of identical length synchronize post-turbine pulses — cleanest high-RPM note.
• Sharp Metallic Sound: Titanium's material nature produces a higher-frequency, sharper exhaust note.
• CNC-Bent Piping: Smooth internal surface, flow-optimized geometry.
• Customer-Selectable 90 mm Exit Tips: Polished Titanium, Blue Heat-Tinted Titanium, Matte Carbon Fiber, or Glossy Carbon Fiber. Twin outlet, laser-welded.
• OEM Hanger Compatible: Direct bolt-on fit to factory exhaust hangers — no hanger modification required.

Titanium vs. Stainless Steel — This Is Titanium

This product is the Grade 5 titanium variant:

• Titanium Grade 5 (this product): Noticeably lighter, sharper metallic note, natural heat-tint finish, premium price tier
• T304 Stainless Steel: Durable, deeper sound tone, lifetime rust-resistance, more affordable
• For weight savings, premium aesthetic & track-day use: titanium preferred (this product)
• For cost and durability balance: stainless steel

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

All three configurations sit at the same price tier — there is no price difference; the choice is about sound character:

• Single Mid-Pipe: Clean flow path, more tonal and daily-friendly sound.
• Double Mid-Pipe: Twin parallel flow paths, more aggressive and fuller sound.
• Equal-Length Mid-Pipe (this product): Two parallel pipes of identical length, post-turbine pulse synchronization — cleanest high-RPM note and 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 catback on hanger points and torque the v-band clamp (torque: 12 Nm).
6. Avoid over-torquing titanium clamps and bolts.
7. Pair the wireless remote and test valve open/close operation.

Care & Maintenance

Titanium naturally develops heat-tint — a patina valued by manufacturers and enthusiasts. Wipe polished titanium surfaces with a soft cloth. If you selected carbon fiber tips, use a carbon-safe cleaner. Re-check bolt torque after first 500 km.
