Review on πŸ”Š MagnaFlow Performance Muffler 12588 - Straight-Through, Oval Center/Dual Exhaust, 4in x 9in Dimensions, 3in Inlet/2.5in Outlet Diameter, 22in Body Length, 28in Overall Length, Satin Finish - Deep Sound by Mario Beckwith

Dimensions are ID So plan accordingly

Important Notice. The size of the inlet/outlet holes corresponds to the inner diameter. Very important if you plan to pinch like me. I installed this on Tundra 5.7 2008. I wanted something complete and it was just the ticket. It's slightly louder than the original with a much more pleasant tone. Very slight hum around 1700 rpm. Excellent build quality. If you want something louder, go for the 12288. Same size inlet/outlet but shorter body.
