ISR Performance Universal Exhaust Silencer - 4-Inch (IS-UNIS-4)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
The ISR Performance Universal Exhaust Silencer (IS-UNIS-4) is a practical solution for drivers looking to manage exhaust volume and cabin drone without replacing their entire performance exhaust system. Designed as a direct insert for exhaust mufflers with a 4-inch outlet, this silencer helps reduce decibel levels to better meet local noise ordinances or track sound restrictions.
- Precision Fit: Specifically engineered to slide into standard 4-inch (approx. 101mm) exhaust tips.
- Durable Construction: Manufactured from high-grade stainless steel to withstand high exhaust temperatures and resist corrosion.
- Noise Reduction: Effective at dampening the raw sound profile of high-flow mufflers, making long-distance highway driving more comfortable.
- Simple Installation: Removable design typically secured with a single bolt and nut through the bottom of the exhaust tip.
- Manufacturer Part Number: IS-UNIS-4
Please note that if your exhaust tip is not pre-drilled, a small hole must be drilled through the tip to secure the silencer mounting hardware.
