ur megane r26
well i finally got around to fitting my decat, i got a new gasket and the bolts came off pretty easily, put it all together, went for a little drive and it sounds as though it is really pissing out air but its not coz i cant feel it, but it sounds soo rattly, so i tightened up the bolts and still the same, i am just about to try the new gasket on the other way around, to see if that does anything, but if it doesnt then i will remove it and put the old cat back on, the thing im asking is is it ment to sound like this? cheers people, quick reply would be handy
