Found a corsa muffler, will it work?

[JDeere7296]

Hey guys...I ran across a couple corsa stainless mufflers. They are 27.5" OAL with a 16" long x 5.5" round muffler body. They have 3" inlet/outlets. Story from guy who sold them say they came off a prototype Datona race car when the cars were required to be below a certain db.

 

Question is I have a 2014 Silverado 5.3 I wanted to change the muffler on. Would these work? Wonder if I could do dual muffler setup with them? Any suggestions are appreciated.

 

Pic looks as if mufflers are different size but they are the same.

Dual 3" would be too big.

I kinda figured two might cause too little back pressure, I could always install one I guess. I was just hoping there would be a way to incorporate both of them maybe.

I would just run one and if it drones or is too loud then incorporate a small resonator or bullet muffler upstream of the muffler.

OK, thanks....I'll try that!
