Tickets?
I started my car with only headers no cats and I guess because of the cam I had and the O2 sensors being so close to the end of the collector it was pulling air back in the collector. Made it run very very rich and fouled the plugs twice just driving it up and down my driveway. After I installed the rest of the exhaust it ran fine.

I have been driving my 97 firebird LT1 open headers only since spring of 2011, no tickets and I'm still driving it like that, I like the sound of the HOOKER headers. My car runs fine without exhaust, the gas smell is strong but you don't notice it after a few miles down the road!!
