i know you will be sick of me going on about exhausts lol but i have got one that fits apart from the flange to join to center pipe its rotated slightly the wrong way and cant get the bolts in.

i heard somewhere you can get a flange conversion kit but cant find one anywhere.

does anyone know what i can do or were i can get one.

 

i have a impreza gx sport 03, the backbox i bought is off 92-00 UK Turbo, Wrx, Sti.
