I have a 97 2.0 Jetta that’s had the muffler removed and a pipe welded up in its place. It makes some pretty loud pops and bangs on deceleration at higher rpms and some nice burbles at lower rpms but I was wondering what the chances are of getting some flames out the back with a CAT delete and an ECU chip that adds more fueling so there’s some extra fuel going out the back and no CAT to catch any sparks. I’ve seen N/A 2.0 Jetta’s shoot some big flames with a stand-alone ecu and a 2 step tune and was wondering if this might be a cheaper alternative to a full ecu.
