Size of the orginal Cat connections

[Shirunai]

Just as the above, can i fit a s14 frontpipe and catback on the orginal cat, does it have 3", my thoughts are "nah prob not"

best regards shirunai 200sxOGS club sweden

That should be fine

all Cat back systems should fit on the end of the cat and the front pipes that I'm aware of have the original mounting pattern so should be good too.

Cat replacements have the same length and flanges as the original so everything should be interchangeable

yeah it works, just called a friend who has a 400bhp s14, he told me it works, cool now i can go through MOT (in sweden we call it SBP)
