GReddy vs. Magnaflow - GAINS
 

I know about the sound differences between the EVO and the Magnaflow... from purely a gains standpoint, which one would give the most benefit? Also, is one better constructed than the other?:susp:

Greddy all the way. Greddy is made better while magnaflow is a better deal for the money. But either way they are both good, Greddy just has a good reputation and high quality while Magnaflow is decent quality with good customer satisfaction.
