EH Downpipe CEL
Does anybody have the EH downpipes? ig:eh_exhaust
Im looking into these downpipes because they claim that you dont need a tune for the CEL since they have dummy sensors. I just don want to pay an extra $1k+ just to tune away the CEL.

You will definitely get more sound, but you may make less power than stock. If the DPs do not trigger a CEL then you could go with a piggyback like the JB4. IMO a tune or a JB4 is the best money / modification you can do to a c43. Night and day performance difference.

Fitting decat downpipes without a tune, just for sound is a dumb idea.
On stock boost with less back pressure, your turbo will take longer to spool and you will lose low end torque, and have spent $1k making your car slower.
If you only want more sound do a centre res delete .
