ST 4000 = better ET with ET Streets or Slicks
YTP 4000 = better from a roll.

ST 4000 will be a little tighter, but both will be loose relative to a 3500 street converter.

Agree with Ragtop.

ST4000 hits the tires much harder. Good if you have traction, bad if you don't.

ST4000 has better throttle tip-in during street driving.

TP4000 is a better street racing converter. More controllable hit off the starting line, it multiplies torque for a longer time period, has longer shift extension, and will put down more rwhp. This will make it better when racing from a roll.

ST4000 is a better 1/4 mile race converter with slicks (very similar to the Vig 3600).

TP4000 is a better all-around converter if you can live with it feeling a little mushier around town.
