Tomorrow we will be installing a set of JBA headers doing a before and after dyno then installing the rest of JBA's cat back exhaust and re dynoing to see results. Finally we will install their power wires and a K&N CAI kit to see max NA gains before tune on our 07 LTZ. Curious to know how many owners are moding their new hoe's. Stay tuned the hoe will also be dropped with a DJM 2/3 kit with pics.
