[QUOTE="ssmann, post: 442287, member: 18956"] Not off the welding mati, but can take one of the welding flexi when the car is hoisted up next. Basically; Welding mati - a steel plate welded to the tailpipe and chasis. When the exhaust vibrates due to rough/poor gear changes, poor use of clutch etc, it vibrates violently. This will cause the welding mati to break loose and then the exhaust box will vibrate non stop and rattles away Welding flexi - first a screw is welded on each side of the exhaust box. Then another pair at the chasis. A flexi rubber hose is used to then hold the two screws together in place, which ensures the exhaust box stays in place, at the same time allowing some flexibility for aggresive movements off the exhaust. This assures the pressure on the weld is drastically reduced, thus a longer lasting weld. This is what I wanted United to do, but they gave me a cock story and charged me RM20 for a weld that lasted all but a week. Even me, someone really non technical on such matters knew the moment I saw the United welding that it wont last a sec!!! Sorry, but really pissed at such poor behaviour [/QUOTE]
