sorry to take so long, but i mean stock as in subaru ecu. including reflash. im not sure if a piggyback like the utec changes this characteristic. standalones may be different, im not sure. i can only personally vouch for my 02 wrx. but i have a feeling that all of our cars operate like this. iirc, the reason srt-4's exhaust burbles and pops on decel is that the ecu is programmed from the factory to keep injecting fuel on deceleration. some of that fuel goes into the exhaust unburned and ignites.
