Catback Exhausts Sr20 = Ka24 ??

[RYS13]

Are the cat-back exhausts interchangeable between the KA24DE and the SR20DET?

[sean350z]

well there would be a difference in:

diameter (SR made for turbo bigger diameter usually)
mounting points (between generations S14/S13)

but other than those two, the mounting points should be the same if it's a catback. i believe the cat is in the same location on a JDM S14 as a USDM S14

They bolt up to the cat location just the same, so yes. Piping diameter may be an isssue (for lack of backpressure) if you're installing a cat-back system that's larger than 3", otherwise they seem to work pretty well.

Exhaust fitment follows the body. An S13 exhaust will fit any generation SR and any generation KA when mounted in an S13 chassis. Same with S14. Any S14 exhaust will fit either SR or KA.

The only exception is the CA. It uses slightly different exhaust so your downpipe may not meet up with the turbo outlet correctly.
