Downpipe is sold!!! Invidia 3" stainless steel catback exhaust system suitable for Subaru Impreza WRX STi hatchback GR models, will fit WRX too if corresponding STi bumper is fitted or just cut out aperture.  It is Gemini R400 catback setup with titanium tips. Intended to replace my loud custom made decat system but circumstances  changed and sold the car. Still brand new and never fitted, still have box. Will cost a fortune now from VIP Motorsport. Collection from Hereford welcome, can post if needed.
