Description
Compatible Vehicles:
- 2025+ G90 M5
- 2025+ G99 M5 Touring
*Available Options:
- OE-style Heat Shielding with ceramic inner liner - signature REDSTAR thermal management feature that reduces radiant heat from the exhaust pipes up to 70-80%. Being inspired by racecar engineers who uses it alot, we moved heat shielding to the tuning industry and made it available as an option for any REDSTAR products. Usual thermal wraps or ceramic coatings are not even close in effectiveness and durability to our Heat Shielding. Please be aware of fake shielding when it is nothing but foil wrapped around the pipe. Without a sufficient ceramic wool layer inside and properly embossed foil it will not work as expected.
Main Features:
- Significant power gain
- No Check Engine Light
- Faster spool up and better throttle response
- Increasing the life of the turbos
- Reducing under hood temperature
- Adds a very nice tone to the exhaust
- 100% bolt-on installation
