hi kev
ive fitted janspeed systems to both my rangies 1996 autobiogaphy 4.6 and 30th anniversary 4.6 they fit well you may have to trim the plastic on the rear bumper if yours is a single exit
mine both run on lpg so i was able to drop the cats, but noticed 30% louder, pulls harder ,engine runs cooler, and slightly better mpg , these janspeed ss systems were on offer at £399 but may have gone up now, very good quality
easy fit direct replacement , sounds great !!!!
