Brock’s Performance Alien Head Full-Exhaust System for Honda’s Grom
Brock’s Performance Alien Head Full-Exhaust System for Honda’s Grom was designed and hand-tuned by Brock’s Performance for stock and modified engines. This lightweight stainless-steel exhaust weighs 4.5 pounds, and this low-mount megaphone-style system is a 100-percent bolt-on kit. It tucks up tight along the engine to provide maximum ground clearance without modifications.
It’s made from aerospace-quality, stainless-steel with a show-polished finish and has a permanent baffle with a two-inch outlet. An optional noise-reduction insert is sold separately.
Brock’s Performance president, Brock Davidson, an avid performance enthusiast and past National Championship-winning rider as well as tuner, takes you along as he explores the performance boundaries of the new Honda Grom in these videos below. The good-humored Davidson takes it in stride when he pushes the boundaries a little too far in the first video.
