Lancasters of 7oaks have fitted a Graham Goode sports cat downpipe for me today on my 02 WRX with PPP and full exhaust turbo back.

What a shock the car is much quicker and there is so much more torque.

Does anyone know what the average gain are for this type of mod as the car feels so much faster right up to the red line.....

Also they were fitting there first STI ppp today they had 2 delivered yesterday..

Who's the lucky owner and what do you think ??
