i was just wondering the fairlane has a longer chassis than a falcon? so an aftermaket falcon exhaust and headers and what not wont bolt onto a fairlane?
thanks

Parts of an falcon exhaust can be fitted. Header/extractors are the same and the section from the cat back can be used but not the tail pipe. If you do fit headers/extractors not all will mount up to the catalitic convertor in the stock location so the exhaust would have to be cut to suit.

so i can run aftermaket falcon headers and piping to the cat but from there on has to be 'fairlane spec'
might just get some quotes from exhaust shops for a system, also the engine bay is the same so i could get falcon CAI and etc? plus lsd?????? i wouldnt mind a better geared lsd i havent seen many for falcons but that would be the same yay? nay?

Both the mid section and the rear section of the standard falcon exhaust will need modifying to lengthen them. About 100-150mm in both sections. Pick up a standard falcon exhaust and get an exhaust joint to lengthen it. Or you could do it yourself with a welder handy
