^^ I second what he said, although I'm peicing a complete one for my truck using Dynomax Pipes with a FlowMaster 40 series. Parts are going to be ordered next week..the mod bug has bit me.
I just need a good muffler shop to have it installed.
Waaay in the future JBAs will reside in the engine bay.
So it wont be a half arshed pipe setup..rather a full pipe setup.
