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.

So much better than a glass pack. Do it!!!
Why did you pick this product vs others?: Love it. Its like a better glass pack. Almost quieter than stock at idle. Loud and raspy at full throttle. Cruising at 80mph its nice and mellow. Pass someone and it sounds like you mean business. And this is side piped ahead of the rear wheel.

J’ai installer ceci sur un Crown Victoria 2009 avec Cata delete ! Pour remplacer mes muffleurs qui c’était défait de l’intérieur et WoW le sons était parfais ! Maudit beau sons sourds et agressif qui fait ressortir la belle sonorité du V8 ! Belle qualité et durable ! Je vais asseiller de retrouver un vidéo!

I put 2 of these on my 3.5 liter v6 camry coupled with a vibrant ultra quiet resonator and it makes a very mellow sound, no rasp no trumpet no tincan ! Impressive for a straight design !

Excellent value for money. Installed this on my 2017 Ram with the 5.7L Its loud under hard acceleration but barely noticeable at cruising speeds, exhaust is otherwise stock with stock cats and rear resonator. Cold starts sound really good 10/10 for a budget setup. This is the 2.5in inlet/outlet muffler but Rams have a 3 in exhaust, just opt for the 3"

Well, built, good quality. Nice rumble not too loud unless you get on it.!!
