Catalytic Converters any comparisons
I was wondering if the Randoms and other after market high flow cats ,have ever been compared to the stock ls1 cats and does the LS6 have better flowing cats than the LS1 .
THE HIGH FLOW CATS seem to be the choice but what HP is gained ? I have
read hear that some 02 codes come up with the high flow cats.
Are they really doing the job? gutted stock cats throw codes also
Do they do the job?
Thanks
John
