I am a little partial here but I would have to say the Project Blaster Phantom pipe. I do not rush into anything when buying something. I done extensive research (3 weeks) and when I was complete I narrowed my choice to 2 pipes. My choices were the Phantom pipe and the Toomey pipe. After further research on the 2 pipes (2 more weeks), I decided on the Phantom pipe due to it's progression of change from a stock blaster to a blaster with motor work. IMHO it is the best pipe for both applications.
