can anyone help im getting the above system on my classic shape sti v2 does anyone know if i can just replace it or do i need to get the car remapped????i currently have a fujitsu jap exhaust syestem on the car which has been on since i have owned it cheers for ya help

 

Don't think a remap is necessary, but it will get the best out of the exhaust

 

I've got an STi V.2 with that exhaust on and a H&S decat downpipe. It doesn't need a remap with just the centre and back box.
