Brock's Performance Grom Alien Head 2 Exhaust

The Alien Head 2™ Exhaust System combines our legendary race-proven performance with the distinctive look and sound of our Alien Head 2™ Muffler. Our most popular exhaust system, Brock personally designed and hand-tuned the Alien Head 2™ Full Exhaust System to find the ideal balance of performance and attitude. Keeping our creative Grom owners in mind, this low-mount exhaust option was designed to tuck up tight along the engine to provide the most ground clearance available. Now you can stretch and lower your Grom without being restricted by your exhaust. 12" megaphone muffler Show-polished finish Maximized power gains on stock and modified engines 2" outlet permanent baffle (glass wool/fiberglass) for long life, deep sound Larger diameter outlet provides increased exhaust flow Distinctive look/aggressive sound (2” optional noise reduction insert sold separately) Pre-installed 18mm bung for wideband O2 sensor Provides maximum ground clearance Over 60% in weight savings No fairing modifications required Aerospace quality, ultra lightweight stainless construction Note: Designed for use with OEM rearset, modification may be required for use with aftermarket rearset Includes Brock’s lifetime direct support package At no additional charge Includes access to Brock's map support program At no additional charge
