Good quality
I haven't installed it yet, but the quality looks really good and the support already reached out and answered a few questions I had. I don't forsee any issues.

Durable, Great Product
This muffler works perfectly. It looks so premium and all the welds are done beautifully. This is quality that is built to last.

these remain closed normally.
I was hoping that like previous valved mufflers I have purchased that these would remain open until a vacuum source was applied. By being normally open, you can just hook to direct manifold vacuum and have a nice quiet ride at idle and cruise... but when you stomp on it and the manifold vacuum drops they open up and roar.... sadly because these operate backwards I am forced to use the supplied pump and remote to make them work.... so far they do work... just with they specified on the page that they are normally closed valves.

It works perfectly
Wow, it really works great! I have a Mustang with straight pipes, so obviously it's very loud, and since I installed these, it's incredible how much control I have over the noise it makes with just the push of a button.

Sounds Great!
Absolutely transformed my Chrysler 300 5.7L! This Valved Dual Muffler Kit is exactly what I was looking for. Installation was surprisingly manageable for a DIYer with basic tools (though having an extra set of hands for holding things definitely helped). The build quality feels solid and the materials look durable. The sound is where this exhaust truly shines. With the valves open, it unleashes a deep, aggressive growl that perfectly complements the V8. It's the kind of sound that turns heads in the best way possible – powerful and authoritative without being obnoxious at cruising speeds. Close the valves, and the exhaust note mellows out significantly, making it perfectly comfortable for daily driving and longer trips without any drone. This versatility is the killer feature for me! Performance-wise, I've noticed a slight but definitely welcome improvement in throttle response and maybe a little extra punch in the mid-range. It just feels like the engine can breathe a bit better. If you're looking to add some serious character and a noticeable performance bump to your Chrysler 300 5.7L, while still maintaining the option for a quieter ride when needed, this Valved Dual Muffler Kit is a fantastic investment. Highly recommend!
