Hello 72step,
I have a set of magnaflows on my 1990 gmc and as for performance and sound they are great. But as for duability and long life I would give an F++++, I had the exhaust installed 17 months ago and the muffler has completely rust out at the rear, and unless you pay the extra for the lifetime warranty on the muffler(had no idea it was offered) you are out the price of the muffler and installation cost. I would suggest you stay with flowmasters, great sound and company warranties there product and stands behind them also. Just my 2cents
