MBRP R1013 3" Inlet/Outlet16" Body 20" Overall Length T304 Stainless Steel Resonator

Hello, do these mbrp resonators slip over the three inch pipe and clamp seal, or do the need to be welded in? thanks

Hi All, did this resonator eliminate cabin droan?

What is difference between mbrp al and mbrp t304 muffler?

There was no stamp or sticker marked inlet/outlet, just wondering if it matters which way it goes in before I install?
