Prevent frustration: buy genuine Guerrilla

Imitation is a big compliment, they say. We are happy with the popularity of the Guerrilla Bypass. But here's a word of warning: the apparently simple yet technically avanced Guerrilla Bypass is being copied. 

Cheap, almost real looking imitations, often from Asia, turn out to be leaky. Most American "cut-out" systems, made from aluminum and steel, usually can't cope with European circumstances. Leaking or stuck exhaust valves result in unwanted noise and the vehicle failing emissions test or periodic examination. "Buy fake and it will break". So: be sure and buy a real Guerrilla product!
