Increases the in-cabin rotor sound by up to 75%
Foster SC Stage 2 Kit works on both closed air box and open filter or aftermarket CAI systems.
No drilling through the firewall required, but opening the existing hole to 1/38 inches increases the whine.
Connects from inlet pipe through the OEM sound tube location.
Sealed sound tube with special diaphragm cap installed behind pedal
No stock sound tube required
- Smooth interior walled high heat resistant tubing
- Rubber grommets for a tight seal and clean install
- High heat resistant braided cut sleeve covers
- Hose ends finished with marine grade thick walled adhesive heat shrink
- All kits complete with Bi-metal drilling bits and detailed install guide
NOTE: Please Note Stage 2 whine mod requires you have the stock sound tube still connected to the back of the firewall. If you don't have it then you would need to upgrade to my stage 4 kit. If you don’t want max whine 100% it’s now easy to lower the volume using my damper cover video below.
