No problem :-)
Running with it on now and works brill infact it's quieter than oem!!!

 

My 04 sti was running 325bhp when i bought it @ 26k miles back in Aug 08, between 30k-40k it ran 390bhp, 40-56k it ran 460bhp and its just hit 60k on the odometer running circa 500bhp. It is used daily on the road and is given some serious abuse when conditions allow, enough to necessitate the need for a transmission cooler on a couple of runs i made up to buttertubs pass last summer (plan to fit one within the next couple of months).... It has been extremely reliable, oil is changed every 4-5k miles and it is always allowed to warm up fully before it is driven hard.
