For a Hilux 2.8L GUN125, here are the two volume-legal paths under NSW EPA 90 dB(A) static:
- Redback 3" cat-back — A$1,184 fitted, 89 dB(A), keeps drone tame.
- Magnaflow mid-pipe + factory tip — A$684 fitted, 85 dB(A), invisible at idle.
Both retain the cat. Use v-band 76 mm for the Redback join — easier service later.
