2016 roush Customer Install & Review

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.

  “Just a big shout out to Shawn for his sound tube kit. He opened up the pathway of whine from my Whipple that I couldn’t hear and now when it screams I can hear that sweet sound. Highly recommended to anyone wanting to enjoy their supercharger sound” Dave’s vehicle is a stick shift and set up mostly for road racing. David Barrow - 2016 GT / Whipple

Foster Stage 2 SOUND TUBE KIT

“I just want to say how thoroughly impressed I am with the creation and execution of this sound tube mod. I can hear the supercharger whine now from 2,000 RPM all the way to redline and I couldn’t be happier!” See the full testimonial Jaime Ohlson 2017 Auto / Whipple

Foster Stage 2 SOUND TUBE KIT

“By far, the best addition to my Whipple Supercharger since it was installed. Brings the fun factor to another level. Every time I hit the throttle, my car sings. It’s really hard not to smile. Driving is a visceral deal. You feel it with the Whipple and can hear it with Foster’s sound tube mod. If you’re looking for that whine, this is the kit. Easy to install and a must have to complete your supercharged experience.”
