I have a set of the spintechs, UNbELIEVABLY loud. I swapped them out for a set of magnaflows and love them.

its not a daily i only drive it on the weekends. im trying to figure out the best sound for when i swap in my new engine. i dont care if its really loud i just want a good overall sound at idle and higher rpms

its sounds like its underwater at idle but at higher rpm it sounds killer.

Spin tech has a smoother sound due to their design. Over the rpm range I feel that spin tech changes sound where the flowmaster 10 series is just loud and stays the same. If u want a little less noise due tailpipes all the way out the back of the truck or try the 6000 series from spin tech.
