No Drone Yet Great Sound!  Anyone with a factory race system will admit that the drone during highway driving is tiresome.  This 4C sport muffler eliminates drone and delivers a sporty sound.   Sector111 were the first to incorporate a Helmholtz chamber to eliminate in-cabin resonance (drone).  Made from high-quality materials in California. This system remains street legal as it is bolted on after the stock catalytic converters.  

No Drone = Blissful Highway Cruising!

  • Helmholtz Chamber is a simple method used to target specific low wave lengths that cause drone
    • Supplier used sophisticated measurement equipment to measure the 4C and designed a system that has no drone yet still sounds sporty
  • Wind & tire noise is now louder during cruising
  • Reduces the flatulant blow-off/wastegate sound as well!  

Street Legal + Sporty Sound = Responsible Yet Happy Driver

  • This is a bolt-on solution that is installed after the factory cat
  • Fantastic sound keeps the sporty nature of the car intact

    --------------------------------

    It actually sounds kind of more sinister at idle from the outside. Quieter but with this guttural tiger growl thing going on. I had my wife drive it around the block to hear it from the outside and it sounds pretty much the same, but maybe at 80% of the original volume. Still the loudest car I've ever owned. 

    From the inside it is quiet until you accelerate. 4k on up is about the same as before. 2,000-3,000 is essentially silent. Even with the windows down. All you hear is tire noise, of which there is a decent amount.

    Customer Testimonials

    It was enjoyable chatting with you the other day to express my more than complete satisfaction in the exhaust system you installed on my new 2016 Alfa4c Spyder...

    I bought the 4c on a whim after seeing it at a Fiat dealer for the first time... 

    I'm not a kid and reasonable in my expectation of a car that cost about an 1/8th of the Lambo. I didn't expect it to sound like V12 but also didn't expect to sound like a kid's Mitsubishi slammer with no exhaust...The car was ridiculous and an embarrassment to drive. The low speed noise over 2500rpm would make the neighbors complain and on the 340 mile drive between Las Vegas and San Diego,  the car was just plain noisy inside...

    Research led me to your solution which looked good on paper and...for the reasonable money involved and a discussion with you, I took a leap of faith.

    That leap proved terrific... your exhaust system not only cured all my noise issues and evened out the sound but enhanced the driving experience of the car.

    If not for your solution I would have sold the car...

    Now I love it. It has entered the top realm of the many exotic cars I have owned...

    Again thank you for a terrific solution to a fatal issue.
