    Rated 5 out of 5 by from Excellent sound I bought this to replace my flow master super 10 that was on my 2014 5.7 tundra. It’s everything I wanted deep aggressive sound. Super 10 was to high pitch for my likings. Sounds really good I’m the cab. I also got stainless tips and they look awesome. Also jegs had my stuff on my porch the next afternoon.
