Dp fix on catless pipes

MTB335 · 12-12-2017, 12:59 AM

Can anyone confirm whether you need to connect the dp fix when installing catless downpipes if you have an MHD tune. My understanding is that you do not need it but if that is correct when would it need to be installed?

Also can anyone advise whether all MHD maps, stage 1 and 2, delete/defeat the CEL when catless pipes are installed or is it just stage 2.

Thanks in advance
