The optional Akrapovič Sound Kit enables owners of selected Akrapovič car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovič technology, drivers can easily switch between the quiet mode and a sportier sound. With the use of a receiver (already included in evolution system) to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller or the new smartphone app (for iOS and Android) to regulate the valves.
An exhaust system is like a musical instrument, converting rough pressure pulsations from combustion to sound, which defines the overall character and appearance of the vehicle. Akrapovič is taking the sound of the exhaust system to the next level, while a team of NVH (noise, vibration, and harshness) engineers carefully tune every tube, muffler, and tailpipe to a specific vehicle. Prototypes are designed with attention to detail to extract the best-possible sound potential. Every prototype is measured with state-of-the-art measuring equipment, which measures the sound of the vehicle’s interior and exterior.
In addition to sound, many other vehicle parameters, such as vehicle speed, rpm, exhaust gas temperatures, and vibrations, are measured and correlated with the measured sound. Data are processed in the frequency domain and converted to 3D graphs, also known as colour maps. Every colour map represents an exhaust system’s sound signature, its identity card, where the sound level is presented in dependence on frequency and rpm.
The team of engineers spends countless days searching for the perfect balance of sound, navigating between sporty and comfortable, refined and rough, and quiet and loud. Prototypes are constantly being improved through on-road tests, dyno testing, acoustic transmission loss, flow testing, and simulations until the required sound perfection is achieved. The sound itself is ultimately still in the domain of the engineers’ subjective judgement, but is supported by objective sound engineering data. Every step in the creation of an exhaust system, from development to production, is careful planned – to the last detail and to the last millimetre.

Easy to break in and good stoppage
Pretty sure these are the wrong brake pads for my Durango can I swap them for the correct ones
This definitely a great fit from the look to the performance. Would recommend it for a clean look in the engine bay
Only gripe is they are a little longer than i’d want but they work like a charm. No need for heat shields on your spark plugs wires.
I never got that order. My new address is 18 Tides Edge Place, Sacramento, CA 95835
Exactly what i needed. I'm so glad these guys could explain the difference in the pad material compared to the 3 other places I called. Will be back soon.

Really great CAI
10 second racing is a reputable company and would definitely do business with them again. They have tons of parts and customer support if needed. Highly recommend them!
Radiator was well packaged came with no dings to the fins. Exactly as describing, fit perfectly. Prompt shipping on the company’s part good communication.
Exactly as ordered, instantly lowered water temps.
The product works good I'm happy with my purchase
Very easy install with the cold air intake, and the power is definitely noticeable.
Solved my belt slipping problem on high rpm track car. Thank you!
Was the best upgrade I’ve done so far made it feel like a new engine and sounds amazing and definitely pulls a lot harder
Easy install and woke up my car!
Works as described. I like the cruise control operation. Easy to go from fun to work mode.
I have run quite a few Hoosier R7's but wanted the size available in the 888R's for my new BRZ. For one thing, I had forgotten how noisy they are! I could live with that if they performed better on a dry track.
When pushed hard for 20+ minutes they eventually build up enough heat to start getting greasy and losing grip.
For many they will be adequate for track days, but I drive my cars too close to the limit. A better tire for me in the dry has been the Eagle Supercar F1 3R's.
Unfortunately the belt did not fit, it was was too long, my fruend had a 2018 SRT, he had the same problem with his order.
The transaction process was easy, the belt seems like good quality, too bad it didn't fit
