UEL Header used:
*Please remember that this header model had to be modified by a professional muffler shop. I highly recommend taking this to a muffler so they can easily modify this header to fit the 03-05 NA 2.5 Forester.

Updated March 2018 (CEL):
1) Did the Non Fouler method, and now the CEL comes on every 3-4k miles! Before it came on every 50-100 miles. So not a permanent fix, but it helps drastically, and is cheap mod to do! Simply reset the CEL with Torque App!

Update 2/10/2018!
After about 100 miles of Driving. CEL Came on while cruising at 60MPH on the Highway..
CEL (P0420 - Catalytic Converter Efficiency Below Threshold)

90% FIX (lol)
Things i have tried regarding (CEL):
1) Non Fouler Method (Fixes CEL Temporarily! Comes on less often) Simply reset the CEL with Torque app synced to (Dongle plugs into OBD2)

Things I did not have to try:
2) Replace Sensor(s) (Not Needed)
3) Replace Cat(s) (Not Needed)
