RE: Fantom pipe
If your looking for unreal power, use the Fantom Pipe with the Losi Adam Drake Header, on a STS Racing Engine (MT.12). It screams!!! That combo keeps up with my other GT with the RB V.12 with the RB pipe & header.
The STS engine is a ton cheaper and just as durable, my last one had 4 gallons of 20% thru it before the front seal died. [8D]
