    exhaust help

    I have a 1.8 sri and have just derestricted the airbox and goin to put on a veccy intake so I am looking for a good cat back system. When i was servicing my car i heard a blow from the exhaust so thought may aswell get an exhaust when i get paid. im looking for a twin piped back box ive seen one on ebay http://cgi.ebay.co.uk/NEW-ASTRA-MK4-...item5632c5cceb its make is cybox. Does anyone noo if they are good and if not what brand should i go for ? And if so should i get the centre box with it for a sporty sound or will i get more bhp without it ? any help would be appreciated thanks.

    Powerflow, Remus, Milltek are good brands, Cybox is a highly rated budget brand which a fair few of us have bought from ebay. As long as you get a free-flowing system doesn't make much difference in bhp if you get the centre box or not, it will only affect sound. You won't be looking at much of an increase with just a cat back anyway. +10bhp max.
