Exhaust System Components:
This exhaust system package includes the following components:

  • Valvetronic Muffler (Compatible with OEM Elect. Valve - No Remote Control Included)

Crafted from premium T304 stainless steel, this direct bolt-on system delivers an exhilarating soundtrack that complements the Mercedes-Benz W463A AMG G63 dynamic capabilities.

Equipped with valvetronic technology, the Fi Mercedes-Benz W463A AMG G63 exhaust system allows precise control over airflow, sound volume, and overall performance, enhancing both power and torque.

With a full catless system, including a valvetronic catback and ultra-high flow downpipe, horsepower gains of 5-10% can be expected on average.

During low-profile cruising, the closed valves channel exhaust gases through the muffler, ensuring a comfortable ride. However, with the valves fully open, the system unleashes an intense and sporty soundtrack, amplifying the driving experience.

Switching between street and race modes is seamless, whether through factory exhaust/sport buttons, drive modes, or the Fi Pro remote control upgrade.

Availability may vary depending on your car model and exhaust setup; please refer to the add-on section and consult our representative for confirmation.

Behind the unique sound and performance lies meticulously designed muffler internals, tailored to deliver an unparalleled driving experience specifically for this car model.

Solid!
Style: AVR-X3800H
It's a rock-solid receiver with modern and future-proof features. Denon isn't the flashiest or most aesthetically pleasing design; however, the unit is reliable and sounds great. I used Dirac Live to fine tune the system, and it's been a worthwhile upgrade from my X-2700.

Great replacement to my older 5.1 Yamaha receiver.
Style: 7.2 Receiver
Great replacement for an older Yamaha. My previous unit lasted 10 years and I see no reason why this new one wont last another 10. Familiar features and setup to other Yamaha receivers. Zero issues with setup and contrary to others, you can use all the features without the app. While the app does add some features for streaming, the unit is fully usable as a receiver for movies, surround, etc. without the app. Overall the sound improvement is spectacular, the high slew rate really makes a difference and DSP much improved over the older 10 year old unit I had. Solid hardware, solid setup and while I'm not about Brand Loyalty, the Yamaha still had better features, reviews and quality than the other major brands. I would have no issue recommending this to unit to anyone. Remember, these units are about the sound they offer, not the the wiz bang features you see in some other units. Reliable hardware, reliable sound and a rich feature set makes this unit a no brainer.

Great receiver for money!
Style: 7.2 Receiver
I got this to replace my lackluster Onkyo TX-NR6050 I purchased from Costco. Three areas stand out for me with the Yamaha receiver: 1: Audio, movies sound great, dialogue is clear. Action scenes are impactful and dynamic. 2: Picture quality, bright, vibrant and beautiful colors from my PC and from my Firestick. 3: Ease of use, out of the box ready to go. Menu is dated (no gui really just an overlay, which is fine by me). Renaming inputs, adjusting speaker settings and setting EQ preferences super easy. Took about 20-25 minutes to fully setup. In those 20-25 minutes I was already way ahead of the Onkyo. Great value for the price! Volume is very easy to set! Still have to test PS5 performance, Bluetooth connectivity, USB settings, WiFi and a few other items. I’ll probably end up buying a Blu-ray player since this was so easy to setup! Or maybe use my PS5/Xbox One :)
