stock cats??
I am wondering if i can run stock cats with my headers or if i really need to go with hi-flow cats? do they really improve performance enough to justify the cost.....thoughts?????

You cant use the stock cats with long tubes. The stockers mount to the OEM manifold very close to the heads(right where the new LT's will reside). Get the high flow cats. Good for the enviorment and making good HP.

It's still against the law to use High Flow Cats because according to federal law you cannot relocate the factory cats. Might as well just get rid of them all together if you are putting on long tubes.
