Hi ,my first post to the forum. However i joined and read through the posts a few weeks before i purchased my 172 clio sport back in september 2011.My question is i am just getting to the financial stage of spending a bit of money on my much loved car.The exhaust on my baby seems to be a mismash of stitched together sections obviously from the wrong models with an array of u bolts and modified mountings it is forever woorking loose on the joints.This car has twin cats as an x reg 2000-01 model ,can i replace these with a single cat as there seem to be an abundance of these on the market but the twin cats seem to be like rocking horse shoes to get hold of.sorry if this question has been asked before but i cant find it in the searches that i have performed.Pete ,aldershot Hampshire
