If you want quiet with a low rumble.
Good quality, but a lot quieter than I was hoping. 5.7L straight pipe to muffler. Had a deep sound but doesn't get any louder even at high RPMs. Cut it off and installed a 40 series.

Flowmaster sound
Little louder than i thought it would be. If you do a resonator delete, it would be very loud and probably have drone. Deep tone until you get on it

Installed on a 2010 Subaru Impreza
Very good quality muffler. The inlet and outlet are both female 2.5, sorry if my terminology is off but you can slide your typical 2.5 right inside either end. It came wrapped in bubblewrap and there was only a very small ding that may have even been intentional. It sounds quiet in terms of other modified cars, but much much MUCH better than stock. It has the low pitched Subaru growl but won't turn necks which is what I was looking for. To my surprise it sounds more pronounced at idle and 2-3k rpm than 5-7k rpm. Also something I haven't seen anyone mention in reviews is its effect on performance, I've noticed a considerable amount of throttle response and acceleration. It's not like you're going to get 1 second off your 0-60 but it seriously improves the fun factor of my car . I was really surprised after-all its only $40. Highly recommended this muffler is such a steal for the money. No idea why its so cheap but I love it.

High quality sound and doesn’t break the bank!
I used this for a custom high clearance exhaust I built for my GX470. It’s a universal fit muffler. It’s high quality steel. My tires are louder than the exhaust. It flows better than factory as my exhaust is much shorter now. There’s no annoying rasp or drone at highway speeds.
