I noticed a nice CFM table comparison of the various throttle bodies' flow rates posted. I searched (in vain) for a similar comparison of various exhaust system components or systems.

Anyone have data that we can tabulate? It would be imformative to compare various muffler, X-pipe, Hi-flow cat, cat-back, and tubing diameter CFM rates.

For example, we might just find out that the flow rate of the stock 2 1/4" tubing with Magnaflow mufflers is only slightly less than the flow rate for the Magnaflow cat-back 2.5" tubing with mufflers.

This would provide some potential savings, among other things.

Anyone have any data or ideas on how we could get this data? Please post and thanks in advance.
