Hi all I am attempting to fit my decat on my megane f1 tomorrow and have heard it takes a while :/, basically can someone tell me what exact bits to take off to remove the cat I think it is driveshaft and other little bits ??? Help would be much appreciated
Found this on the other site hope its of some help No "how to guide" but its a challenging job, if you dont have a ramp Get the car at a decent height then mate and you might want a friend close by. Remove: Engine cover Turbo heat shield Lambda sensors or just unplug both of them. Undo 3 bolts at turbo (usually stupidly tight) Remove 8mm bolt holding cat to manifold ( very hard to see so might have to feel around) remove drivers front wheel REMOVE HUB NUT Split track rod end from hub. Undo the 3x13mm bolts holding wishbone to hub. Remove vertical drop link Remove engine under tray Remove subframe crossmember Undo driveshaft clamp Remove driveshaft Remove lower dog bone engine mount and all brackets attached to engine Undo some 8mm bolts holding cat to engine, etc Undo nuts holding cat to exhaust flexi part Undo exhaust clamp and remove front pipe Then it should be a lot of wiggling of the cat and a mate rocking the engine to give a bit more space. Have fun!!!
Hope your doing it on a 2 poster ramp? also found last week that a 3" decat is harder to do than a 2.75" one!
