Has anyone tried the Akrapovic catted downpipe with stock ECU? Any power gain? Did the CEL come up?

the gains are from 10-30 whp depending on your map, also faster spool.

Akrapovic use HJS cats so it should not trigger the check engine light, with that said you can get other downpipes for a lot cheaper which come with a no CEL guarantee
