I know, I know......
I've basically left it alone because of emissions.
There are many people around here running offroad pipes but they either have a way of passing the test or they swap their cats back in temporarily. Haven't heard of anyone getting busted for running without cats but I understand it can be very expensive.

I haven't wanted to get into that game but I guess I need to do something.

Any opinions on the differences between going with an offroad pipe vs high flow cats?

Is it true that I will lose bottom end torque or hp with a better flowing exhaust? What about the 2 1/4 vs 2 1/2 pipe diameter, what's best?
