Is it fair to assume that these inexpensive 200 cell high flow cat downpipes, like other inexpensive 200 cell catted primaries (CTS, ER, RD) are for smell control or to improve the environment, but that they won’t prevent a CEL? The high flow cat primaries that I am aware of this far that will not trigger a CEL are $2000-$4000.
