So I'm not sure where to post this so if it's in the wrong spot please move it for me. I'm looking to take my stacks down and go back to a side exit exhaust. So my question is what is a good exhaust. Who I use a muffler or stay free flowing? I am tired of the in cab noise. Is there a muffler that can quiet it down in the cab yet still be loud? Any input will be helpful. Right now I have no cat no muffler dual stacks. Also how big should I go?
