Services
Performance Exhaust Systems
Grimmspeed exhaust systems enhance engine efficiency and sound quality through mandrel-bent tubing and precision engineering. Designed for specific vehicle models, these systems reduce backpressure while maintaining durability under high-stress conditions. Each system undergoes extensive dyno and street testing to ensure optimal performance gains.
Turbocharger Upgrades
Our turbocharger kits increase horsepower and torque through larger compressor wheels and improved airflow dynamics. Engineered for reliability, these upgrades include reinforced housings and upgraded bearings to handle increased boost levels. Each kit includes detailed installation instructions and tuning recommendations for safe power delivery.
Suspension Components
Grimmspeed strut bars and cross braces improve vehicle handling by reducing chassis flex during aggressive driving. Constructed from aircraft-grade aluminum, these components provide precise fitment and long-term corrosion resistance. Installation requires basic mechanical skills and standard hand tools for most applications.
Intake Systems
Cold air intake kits maximize airflow to the engine using high-flow air filters and smooth aluminum piping. Designed to fit factory mounting points, these systems improve throttle response and horsepower gains across the RPM range. Optional heat shields help reduce intake air temperatures in high-performance applications.
Warranty Service
Grimmspeed offers a 12-month limited warranty covering manufacturing defects in materials and workmanship. Customers must provide proof of purchase and installation details for claims. Warranty service includes repair, replacement, or credit at company discretion, excluding damage from misuse or improper installation.
