richard want to fit a sport cat to my 2.5"exhaust system and front pipe is 2" i think what size sport cat would be the best to get i know they will all have to be made to fit but which size would be easier to make fit 2.25"maybe dunno..
vocky I would get a 2.5", then use a 2"-2.5" reducer might be worth getting daz to knock you up one of his 2.5" downpipes, he's the exhaust specialist :lol:
