My CVFab downpipes came with extensions for both sides. I’m having a trouble code problem (P2098) and was told to take the extensions of the after cat O2 sensor and run them for 30 miles delete the the rich code and replace the extensions and it ”should reset the sensors. Problem, can’t take the extensions off due to interference with the floor pan. Asked cv fab if the extensions were side dependent and they claimed they were universal. So I’ll try one more time (two mechanics say they won’t come off without disconnecting the downpipes from the turbo. Cv fab says they just unscrew.) Just don’t want to disconnect the turbo-downpipes flanges twice.
