both of these units can be had for about the same price off ebay, i know that the magnaflow and carsound units are essentially the same, but what about the catco unit? does anyone know which one flows better? test results?
Magnaflow is widely considered to be the best performer by most exhaust shops. I suspect they would know, but I've never tried to find flow data comparing them. Doesn't catco typically deal with OEM? As in not performance or hi-flow?

well here would be a catco for my car http://cgi.ebay.com/ebaymotors/2-25-...spagenameZWD1V
it says it can be a performance part or stock replacement, but that applies to most hi-flo cats i would think...marketing ploy is all that is.
