after i instald the xpipe from 928 motorsportsd and removed the cats the car run pretty good and the sound from the exuast is nice, no smell or nothing like that.
Until one day about a month ago i replaced all the vacuum lines. Now lets just say that when ever my car is running i can accualy see the hole in the ozone layer getting bigger .
So i think some hi flow cats might be in order
