Another quick question - I'm sure someone must know the answer to this - I remember that Stu (53WRX) couldn't fit his H&S back box to his new car as the diffuser was in the wrong place.

Does anyone know if the same applies to a 55 plate blobeye STI?

I ask as I've decided that the Prodrive back box on my STI, whilst it's still loud(ish), it really doesn't have the same noise that the H&S box has, so I want to fit my old one onto the STI - but will I have the same problem as Stu or will it go on without any problems?

 

I think it`s only if yours has this thing at the back.



this is a H&S back box it needed to be made to miss the diffuser.

I didn't think the Blob STi 55 had a rear diffuser ? I think Elmer fitted an aftermarket one to his but is wasn't standard to my knowledge. It was only the diffuser that got in the way of mine and I didn't want to trim it, yours will be fine same fitment as before.

 

Cheers everyone - will pop down to H&S as soon as the opportunity allows to get them swapped over.
