Optional Upgrade

Unlock unparalleled performance with Palenon Performance’s 5-Inch bmw B58 Downpipe, the largest on the market. this b58 downpipe features a smooth transition from 4.5” to 5” to 4” and ultimately to the OEM connection of 3.15”. Unlike other downpipes that quickly neck down to 3” at the flex joint, our design maintains larger diameters throughout, ensuring optimal flow right after the turbo.

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.
