Over the course of the years, we have had, Magnaflows, Gibsons, Corsas, Spintechs, Flowmaster.
Here is my input:
Corsa>Magnaflow>Spintech>Gibson>Flowmaster
Exhaust is a matter of opinion for the most part (ie. sound). They don't offer that much performance, but can sometimes hinder it depending on your application.
The Corsa had the most "flow through" and least drone, the Magnaflow had a great flow, but a tad bit of drone, the Spintechs are louder than the Magnaflow with ok flow, the Gibson had a popping/tinny noise, and the Flowmaster was the loudest with the worst flow of them all (due to the chambered construction).
I am in no way affiliated with any of these exhaust companies, just going off of my personal preference.
