2021 Catless with JB4, no tune no CEL

[underdonk]

I'm still apprehensive with $1400 for a DP, but I spent money on everything else . Gonna keep the Stock DP and run HKS Carbon intake, Tomei Exhaust, with the JB4. But you never know. Once I get gapped by something surprising which can be anything, Might just go full send and say fu** the warranty.

Been running catted AA for 3k mile with no CEL. Just for more data. Amazing quality product too. The guys at the shop I take the car to were impressed. They do various categories of racing up to pro-level and know their parts, so that made me feel like it was money well spent. Good luck!

Awesome. I’ll definitely take a look at it in the future
