N63 Exhaust question - OEM front half
Any help here would be appreciated. In the attached diagram, pic, why are the front "silencers" different styles and dimensions on the N63?
I presume neither is a secondary cat? (I hope?) I ask because in the process of building my custom exhaust, we are getting some weird exhaust tones/pulses, and are going to start modifying components via a process of elimination - and these front silencers have come into question. Thanks! |

Neither is a cat based on price alone from a few online sources, plus they are listed as "Center mufflers," in the descriptions.
That said, since they are different sizes, one could assume it's for addressing different harmonics. Which is what you are trying to address.
