Intake + Exhaust = what hp gains overall?

Let's say I were to get hfc, wouldn't I need to do something else for the O2 readings? I've been searching on the forum and some have said that a service light keeps on appearing after installing HFCs.

Not really looking into TP.

IF for whatever reason you get a CEL, these will solve your problems. I didn't buy the L bend ones particularly. I bought 4 3" ones and double stacked on each side so effectively 6" on each side. CEL went off and never came back. I'll be doing the same thing once my test pipes get here.

O2 extenders help, but you can still throw a CEL with them. There really is no full proof way of eliminating CELs with TP or HFCs unless you get a UPREV tune and close the loop to those sensors.
