I want to remove my cats from my 2002 Silverado 5.3 Truck. What results have you folks had when doing this any problems? what are the gains and what are the losses. I already have purchase O2 Simms for this. Any Suggestions?
Thanks Lee Stroud!

 

I had been running my SS for a year w/o cats and used Simms. But I put them back on when I found it is against the law and up to a $50,000 dollar fine.

 

Worth about 7 RWHP on a bolt on car..It is against the law and will make it hard to pass inspection. YOur exhaust will be stinky too. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
