Cat help

[TheBigBlackHD]

I have a 99 Sierra with the 5.3 and stock headers, cats, and a cut-out. I want to replace the cats but DONT want to eliminate them all together. Whats a good sound/performance cat for this?

What would be the best for a true dual setup? I hear Magnaflows are good, but which type?

For your truck or the 5.3?

If its for your 5.7 then this will work well.
