Optional Upgrade

For the ultimate performance setup, pair the Cat-Back exhaust with one of the Palenon Performance Downpipes for improved exhaust flow. The full exhaust package includes a stainless steel downpipe for maximum gains.

CEL Delete Kit (Optional)

When installing catless downpipes, a Check Engine Light (CEL) may appear due to the removal of the OEM catalytic converter. To avoid this, Palenon offers a CEL Delete Kit that includes O2 sensor spacers designed to comply with BMW's emissions parameters. These spacers install into the post-catalyst O2 sensor bungs, effectively removing the CEL without needing a tune.
