This is the 3” model but has smaller 2.5” internal tubing, not a big deal to me as it doesn’t seem to lessen any power seat of the pants-wise. The one with the matching 3” internal tubes also has a 5” case that wouldn’t fit my application unfortunately. I went from Thrush 3” Rattlers to this Dynomax and it definitely quieted down but still has a great sound, just nowhere near as deafening as the Rattlers. 4 stars because it’s not a genuine 3” muffler all the way through.
