Does that $130 cat actually flow better than the $45 dollar one?

[SVOandSVT]

The question really sort of says it all. Does the $130 Dynomax super converter flow appreciably better than the $45 14" CATCO unit? They are both 3" inlet and outlet. Is it worth spending the extra money?

I don't know about flow rates, but my Dynomax still looks new after 3 years.

The factory style cats such as that walker definitely have a much longer serviceable life expectancy than the Catco. I've seen Catcos that last a few years, and the original style that are working on their second decade.
