MODERN CARS ARE QUIET

As sound proofing technology has improved, muscle cars isolate the driver from the rotor whine that muscle car drivers absolutely LOVE

THAT IS ABOUT TO CHANGE

Foster SC Mods Sound Tube Kits, have been developed to increase rotor sound in the cabin by up to 100% and give drivers the thrill they really want.

BEECHMONT PERFORMANCE FORD, OH

At Beechmont Ford Performance, we build custom Mustangs and ship them all over the United States. To say that I’m a car guy would be an understatement. The one thing I’ve missed from the Terminator and Lightning days is the supercharger whine. I thought it was a thing of the past until I stumbled on to Shawn’s sc mod. Just installed it on my personal GT500. Wow, what an amazing upgrade. You won’t find more fun for any where near this price. I’m going to start offering them as an option on our custom builds. Outstanding…wow.
