1jz exhaust

I have a 3" exhaust up until the pipe splits into two near the turbo's. The pipe that branches off into two parts is stock. That pipe has an oxygen sensor on it i think. Is it worth getting an after market pipe?

if so, what is this part of the exhaust called?

I have seen a supra with the extra pipe work and he was boasting over half a second better quarter mile times than me with nothing else different than my car. Could this be why?
