The OEM-Nissan exhaust hangers were worn out (175K, 17 years) on my vehicle.
The 2" secondary from SSAC would not clear the Progress LCA brace.
I installed new Nismo exhaust hangers. Much, much tighter and stiffer than new-stock, and a billion times better than the worn-out stock ones on my car.
The 2" SSAC secondary now clears with no issues whatsoever.
Your exhaust hangers are critical to clearing
any lower control arm brace with
any aftermarket secondary.
And go with Kartboy hangers, not Nismo. The Kartboys are inexpensive and equally good. The Nismo ones say Nismo on them, therefore they are stupidly expensive for exhaust hangers.
