I need to get some info on catco cats to see how well they compare to carsound cats.
Ive found a review showing the carsound cats flowing well but I did not see one of catco's.
Im wanting to know catco's flow numbers because they are about 25 bucks cheaper a piece.

They would be 3 inch cats.

If anyone has any info about how well catcos flow or know of any sites showing test results i'd really appreciate it.
