Exhaust pricing

[LFD132]

Here's my situation:

I already have a delete pipe with bung holes for the sensors that I bought with my spartan. Since I no longer have the spartan and went with H&S MINI MAXX I am trying to decide if I should use the delete pipe I have and go with a new exhaust from the delete pipe back or buy a new exhaust system that would go from the down pipe back and not use the delete pipe. Since the mini maxx doesn't need the sensors would I have to plug the holes on my old delete pipe if I use it? Would it be better to have one complete system?

Who has the best pricing on a complete system with the muffler? I don't care if it is all stainless or aluminum as long as the tip is stainless.
