Engine misfire
#1
I have just fitted a S/S exhaust to my Impreza STi. It has a de-catted down pipe and centre section with a back box. I am unsure of the make. Since the exhaust has been fitted in 3rd or 4th gear at about 3500 to 4000 RPM the car misfires. Should I put on my own sensor on to the new exhaust as the new exhaust came with a sensor or does the car have to be retuned after putting on the new exhaust?

Does it "misfire" under full acceleration?
I had the exact same issue with my fully decatted SS/MY00...it's overboost mate, and the boost cut feels exactly like a misfire in the newer scoobs.
There are ways to sort it, fiddle about with restrictors...or do as I did...get it mapped (Link).
