FREEFLOW EXHAUST; G87 M2

Part #: D660-0100

Like its brethren, the M3 and M4, the G87 M2 is a giant leap forward from its predecessor in terms of overall performance and its capabilities. Not surprising given the latter model borrowing heavily from its older siblings' part catalog resulting in a wide swath of components being interchangeable amongst the trio. A few inlet pipe bends prevent the exhaust from being one of those but the M2 is still largely the same as the G8x M3/M4 system. This allowed the extensive drone abatement development applied on those platforms to be used on the G87, fast tracking the R&D process. The result is the introduction of another member of G8x valved axle back exhaust family that elevates the tone to a deeper, more meaningful note while also delivering an extra level of amplification above and beyond its stock counterpart.

Features:

• Maximum gains of +6 HP and +5 lb-ft of torque
• Enjoyably louder, sportier sound
• Drone abatement technologies used to reduce cabin resonance
• Four, diffuser filling, 4.5-inch (114mm) double-walled, polished stainless steel clamp-on tips with laser engraved Dinan logo
• Larger diameter piping for increased flow (76mm vs. 70mm)
• 6-pounds lighter than the stock axle back (Stock: 44-pounds vs. Dinan: 38-pounds)
• Stock exhaust valve actuators reused, and operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-drive settings
• Computer controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions
• 100% 304 Stainless Steel construction
• Factory-like fitment with included mounting hardware
