My 86sc t1 car no cat and glasspack cackled and popped on decel. My srt swap no cat 2 resonators cackles and pops on decel. My 88t1 with intercooler no cat and vibrant muffler doesn't cackle or pop. It is still running on the automatic cal but I'm just wondering why this car doesn't do it when every other turbo dodge does.
