Tom,
Why does the other challenge X pipe cause NO CEL? i know the other model has high flow cats but doesnt the Akra evo also have hFC? but the evo throws a cel. so why is it that the challenge one doesnt throw a cel but akra evo does? i thought all xpipes that are non oem cause CEL...forgive my ignorance..trying to figure this out to make a decision....im just worried about getting the CEL deleter and then not knowing if its deleting other important warnings non related to emissions...and then ill be driving around not knowing if something is wrong
Also, whats the difference in sound between the other challenge pipe vs this one here?
