Exhaust question

[Bammer25]

Searched and couldnt find much. What is the little can on the tail pipe down stream from the muffler just over

the rear axle?  I was going to switch out my muffler and trying to figure out what I want to delete (cat, resonator, muffler, etc). I know some leave the piping and tailpipe after the muffler stock, which was my plan. But what is this thing?

Replace factory muffler with a muffler of your choice, remove resonator (near tail pipe).

Or just remove the muffler, replacing it with a piece of straight pipe and leave the resonator alone. 

 Simple, inexpensive and works fine. 

 

- give it a shot, the cost is right, if you don’t like the outcome, you’re still at square one.

I guess I was confused. So the resonator is the piece by the tail pipe? I thought it was up on the other side of the muffler beside the third cat. That piece of flex material

The thing up front is called the flex pipe so the exhaust can have some play to it. Depending on the year of your truck it should be muffler then flapper valve and resonator which is the thing above the rear axle.
