Hi All,

Ive already got a scoobysport back box, and have decided to go for the mid section too.

Running a MY01 WRX, itg filter and forge dump valve also.

Im hoping that having 1 less cat will give a noticeable gain, is this likely if only small. Also, whats the noise difference like?

thanks

I had the mid section on my 01 wrx but kept the standard res box
section on so noise was no differece.The car seemed to rev more freely higher up the rev range,but at the expense of initial throttle response,which was a little surprising.I have also found the same result on my sti7 which had a noticeable increase in throttle response when I put the cat back on.
