The kits that are dumped at the axle are too unrefined for my taste because of how loud they are and how much ground clearance they give up.
Universal kits work as long as they have a volumetric (better) xpipe, and as long as you have a good exhaust shop/welder doing the work.
3" is going to be slightly louder and deeper than 2.5". 2.5" is all you need for most applications.
