sweet you may have changed my mind. you reckon if they cut the axial pipe from the centre box too short thats what might make it rattle or will it rattle anyway
In all honesty i haven't noticed it rattle. But then i have my music turned up so that may be why. The only problem i had was when the rubber bracket mounting thing cracked and therefore had a bad vibration/rattle. Other than that cant complain.
Im not too sure about the fitting to be honest. I had a mechanic sort it so dont know. Sorry.
