Having owned a 1996 STi, for some 6 years the exhaust started
to blow. Holes appearing in the section below the Catalytic
convertor before the middle box.
An examination of the system revealed that most of the system
was showing severe signs of rot and would soon start to blow
As a result I tried find a replacement unit. Subaru UK were
singularly unhelpful since this was an import and they would
not supply anything for it (which I thought was against the
law), anyway I wanted a Stainless system.
Calls to various “sports” suppliers ended up with
being told to bodge an Impreza system to fit and “fit
the old cat part for an MOT, then put the Impreza bits back”.
I thought this a joke!!
So we have made a bespoke system and can now offer it to other
STi / Turbo Forester owners, It fits inplace of the original
parts or complete, with Cat and Lambda sensor bosses and the
special flanges used to allow engine movments. It is a direct
replacement. It sound quiet (as the original) and will last
the life of the car.
