I have MS modded Stillen ICs. The thick Stillen cast ins/outs were cut off and replaced with thin walled aluminum piping by Mike Smith. According to SZ this piping mod alone is worth around 20hp at the 500hp level. These are the best flowing ICs for stock piping, and is noticeable on the top end. I crafted some homebrew ducts out of sheet metal as well.
I also have full (intake/OEM IC/IC pipe) OEM piping available.
Im looking for someone who is on stock piping and wants to downgrade from their AshSpec 2.5in ICs. I will include cash, depending on which 2.5in IC you have to offer.
