Default sports cat / exhaust

i have a 2002 bug sti

so far i have decated the center exhaust , walbro pump and panel filter and re-map,but it still has the original exhaust fitted.

how much of a difference would it make if i was to fit a sports cat and a milltek system ?

Thanks

My sti hawk made an extra 70 bhp after fitting a milltek exhaust with sports cat. Very good quality bit of kit.

210 bhp, just sounds like 300...

P.S. You need to map a car to get 70 bhp.

What increase did you see from your first set of changes and how did it effect the overall drive?

probably about 30hp ish , the changes made the overall drive a hell of a lot smoother right through the rev range .
