Awhile ago someone posted up test results of our stock cats vs flp, carsound, and some other one (that did horrible). It showed the FLP being the highest flow then carsound... but it didnt have catco's in the test.
Im asking because i can get catco's 15 bucks cheaper than carsound cats.

I would rather spend the extra 30 bucks if it were giving me 3 or 4 horses.
