After 4.5 years, the Flowmaster 50 SUV (non-SS) system rusted out, muffler fell off this week and had to run a straight pipe for a few days, had to wear ear plugs!
Instead of the duals, I went 3" SI/SO Flowmaster Super 50 SS w/ a 4" SS dual-wall tip (similar to a Corsa tip), fully welded this time. Love the sound, nice and quite at idle and cruising w/ zero drone, but a beast at WOT! (I should have put the camera at a different angle, other than directly in front of the the tip)
