The installation of a catless downpipe on your VW will result in an inevitable check engine light (CEL) as the ECU will detect that emissions are not being burnt-up by the OEM catalyst. To remove this CEL without having to tune it out we offer the CEL Delete Kit which is comprised of an O2 sensor spacer specifically designed for the VW. This installs into the post-catalyst O2 sensor bung on the downpipe,effectively removing the CEL that would otherwise appear.
