Test pipes.
I've been happy thus far w/ my resonated OBX setup, and no CEL after 12k miles. Here's my review thread on them. And if you do decide to go w/ test pipes I would strongly recommend a resonated version whichever brand you go with. https://www.myg37.com/forums/engine-...est-pipes.html ***It appears that the OBX pipes aren't available, at least from that vendor. The Fast Intentions Resonated Test Pipes are a solid performer and utilize the extended/curved O2 port (which I assume the OBX used as their model) and this should keep the CEL from being activated.
