Grail exhaust system suitable for BMW M235i F22 Coupé (N55) – valved exhaust system

The BMW M235i F22 Coupé (pre-LCI 2014-2016) is the direct predecessor of the M240i - with the N55 straight-six and 326 hp. Free-revving, agile, in character an early hint of the M2. The GRAIL valved exhaust system gives the N55 the acoustic range it deserves: strong in Sport, restrained in Comfort. Made from L304 stainless steel, CNC-machined to close tolerances, with ECE type approval - no registration required on any EU vehicle with standard type approval.

Valve control - two versions

Before ordering you choose the valve control:

• Factory valve control: uses the factory BMW valve control of your M235i via the driving modes (Sport / Comfort).
• ECE R-59 valve control: a separate module is connected to the CAN bus. It reads speed and engine revs and opens or closes the valves automatically. ECE-compliant in both valve positions.

Exhaust tip versions

Before ordering you choose the finish for the rear end:

• Stainless steel: classic and sporty, a near-factory look with more presence
• Black: matt black finish, understated and bold at the same time
• Without exhaust tips: for your own aftermarket exhaust tips - you save the cost of the GRAIL tips.

Highlights

• Specifically suitable for the BMW M235i F22 Coupé with the N55 straight-six (326 hp)
• Two valve control options: factory control or ECE R-59
• ECE type approval - no registration required within the EU
• L304 stainless steel, CNC-machined components
• Developed and made in Germany
