How can you tell the difference in backpressure? I am looking at 3 options:
-MagnaFlow part# 14378
-Cherry Bomb part# 88115
-FlowMaster 50 Series SUV part# 524554
All are dual in/dual out (2.25") except the Cherry Bomb is (2.25"in/2.5" out). I plan on replacing the old OEM Cats with MagnaFlow Cats (part# 54305) as well. I am tired of the very loud PV1, and want to try something new, hopefully a little more quiet, PV1 sounds a little ricey over 4K rpms.
