Simply stated, the benefits are in the name; they flow the exhaust gases better than the stock cats. They also keep you emissions legal except for more restrictive states like California.
RJT-SS pretty well nailed that one Thapilot. Anything you buy aftermarket if going to be high flow. I do not have any hands on experience with TSP headers so I am not in a position to comment on them.
