Has anyone emptied out the cats on the stock 03 midpipes?
These pipes are 2 1/4" and are said to give good low end
torque on stock engines.Will the car pass the emissions
sniffer test with the cats empty?
I had a 1986 Monte Carlo SS, I emptied out the cat and it
went .10 faster at the dragway and passed the emissions.
Can you even get something into the pipes,to reach the cats?
