I've got VRSF catless DPs (Velos Stg 2 and Fabspeed exhaust) Sounds mean as piss! And turbo spool is very noticeable...some think I'm a diesel...lol.
Unfortunately, I can't pass inspection with them on. So I will be removing them
Tried the Fabspeed catted spacers to no avail.
Def I great improvement with them on
