Because if there's a DTC and no light I'm doing the dp, but if there's a ses light on at all time, I'm not doing that to my daily. Also, what is this idle issue ppl are having at stops? Is it all the time? Just a few concerns im having before spending the money, time, and effort.

I'm a noob to the forum so thanks everyone.
JB4 autoclear removes the code completely, no SES; but, you won't know if there's a bigger issue looming in the shadows either.

I'm seriously about to just pull the trigger and get an expensive high-flow catted DP. I am not really having any idling issues but I'm not a fan of my JB4. I will probably switch to Cobb AP for tuning once I get that high flow cat.

Actually real codes still show a light in dash. Only passive codes are hidden. Remember though catless downpipes are only for dedicated race cars!

On the E series N55 JB4 are you using the new N55 ISO firmware yet? I hear it's a pretty significant upgrade in terms of smoothness and power compared to the integrated firmware they ship with.
