Great build quality. I chose FI due to sound, design and price. It cost 3k and the install is going to be $500

Nice. This is something I'm thinking about as well, since my 17 c43 doesn't have the performance exhaust.
Where would I take it to get it installed?
Any muffler shop?
Looking forward to hear your results after the install!

I recently got my Armytrix exhaust, a little on the spendy side but worth every penny. I love the sound, also installed eurocharge stage 1. This thing is a beast & I’ve heard this is now comparable to a C63s

Not all muffler shops can do the valvetronic exhaust. just search for a performance shop. I'm taking it to an authorized dealer for FI

Armytrix was my second choice. I just rather have a X midpipe than a Y midpipe. With the research i did the X is better, but im no expert. What is the warranty on Armytrix? FI is only 1 year which is kinda sad.

X-pipes towards the rear typically cancels drone, this is a good layout. Gonna sound sick! post your review even if you don't have a sound clip yet.

also from what I gather exhaust pipes have to be "broken in" and warmed up for a couple of miles to get the baseline sound.

sorry about the delay on a review.

I'm very happy with the exhaust. It has two methods of switching the on/off/auto valve. I like to use the digital module that connects to the OBD port. It has a button to scroll a display between RPM and Boost and a button to change the exhaust valve. The key fob is the other method, but i never take my keys out my pocket, so useless.

The sound is totally different than stock. I think most surprising is how good it sounds with the exhaust valve closed. the sound is much deeper with a mellow throaty rumble. absolutely no drone with the valve closed.

With the valve open the sound becomes much more loud and aggressive. This is best appreciated in S+. In S+ the burps, bangs and pops are crazy intense and the faster you accelerated and decelerate the more pronounced they become. I do notice a slight and tolerable drone at 2500 rpm.

Overall im very pleased with this purchase. The valve technology is easy to use and must if you want a little stealth. The sound of the exhaust is perfect for me, but that is subjective.

Let me know if you have any other questions. I tried to record video with my phone, but i don't believe revving my engine give the sound justice.
