Hi folks, I’ve been debating a variable volume exhaust for the last little while and finally decided to bite the bullet. I perused the usual suspects - Agency Power and AAM - and they both make quality pieces, but I was quite intrigued by MEGTROC Admin ‘Q’s post about Armytrix. I checked out their youtube clips and website (http://armytrix.com), and after speaking with them on multiple occasions, I decided to take the plunge on their variable volume catback exhaust.
As a complete set they offer catless downpipes, a resonated catless midpipe, and the variable volume exhaust. Given that I already have GTC cast iron downpipes, and a Cobb catted midpipe (I can’t stand the smell otherwise), I decided to go with the variable volume exhaust alone. I know a lot of you run similar bolt-on setups either with or without a catted midpipe.
It’s remote controlled with hydraulic actuators, and what I like about it is that irrespective of whether the valve is open or closed, it flows through all 4 tailpipes (you can see in the photos below). Also, you can select open, closed, or have it automatically open at a set RPM level, which I think is a useful feature.
I ordered it from them on August 12th, and it arrived August 13th. Yeah, that was pretty darn awesome.
I’ve taken some pictures of it sitting in my living room (forgive the rug) and will take more pictures and videos/sound clips when I have it installed this Wednesday. I'll give a full review of the exhaust sound and performance once I have it on there, so hopefully it’ll be helpful for others considering variable exhausts as well.
