Cats or No cats?

[Kryo-Genik]

Quick question on this same subject.

The smell and volume of a catless exhaust aside, do all catless Lightning's smoke like Dustan's was doing in his videos? Or could that have just possibly been due to a cold start?

from what ive seen on ALL catless vehicles.


Cold start means black/dark grey smoke.
Once warmed up no smoke at cruise but once you go WOT there is black/dark gray smoke that bellows out for a second or two.
This is what ive noticed on all vehicles.
