Installing Flowmaster 40 Series muffler..Do I remove resonator? Will resonator make much difference?

Do the muffler first. Then make the second decision.

The resonators make a huge difference in terms of loudness.  You may not like just the flow master if your looking for loud sound

Did  flowmaster 40 on my truck and was PISSED! It was barely noticeable. I covered the mesh screen with some aluminum tape. Made all the difference in the world. Get rid of them!!!!

So how do you remove resonator on truck with factory dual exhaust or can you just put aluminum tape over the mesh?  Are there any performance loss when covering the mesh?

The mesh is just the integrated resonator. There to diffuse the sound and make it quieter from what I understand.
