yesterday i installed kooks headers and highfow cats and when i run my car hard the exhaust stinks it smells like old cats smell when they are bad is this normal for new cats to stink ?
i havent had any problems with 02 sensors or anything else just the smell and when i fired it up for the first time after the install it smoked like a train i gues the headers were coated with some oil or something
That's the smell of high performance! I noticed a little something when driving in traffic today and listening to my Flowmasters. I thought someone farted?
