Purchased 2 of these mufflers to replace the OEMs on my 2016 Hyundai Genesis/G80 sedan. Very impressed with the sound and material quality of these mufflers, meanwhile saving some cash over the name brand competitor that offers them in 409 stainless. These are fully T304 SS (magnet tested) and have a 14 gauge wall thickness! True measurements are: Overall length 19.5" / Body length 13.5" / Body width 9.75" / Body height 4.25" / 2.5" in-out ID.

I haven't run it on this vehicle yet, but it seems very heavy duty and I hope it sounds good. Going behind a rebuilt Ford 300 inline six with a good cam and fuel injection.
