People just blow of data rather than look at it constructively. I thought it was interesting but either way I have my stock exhaust gone and is not relevent. Just thought someone may find it interesting.

not not really it's common sense that the cars (at least in USA) that are closest to the motor, the primaries, are going to do the most "filtering" of the exhaust, hence why they are 99% of the time the more restrictive set. Some cars the primary and secondary are just as restrictive so you remove them all. These cars sound wayyyy to raspy w/ no cats or resonators at all.
