Exhaust System Performance
Q: How much horsepower gain can I expect from a performance exhaust system? A: Horsepower gains vary by vehicle and existing restrictions. Naturally aspirated engines typically see 8-15 HP increases, while turbocharged engines can gain 15-30 HP. Our dyno-tested systems include detailed before/after power curves. For example, our 2019+ Mustang GT system delivers an average 22 HP gain at the wheels with improved torque delivery throughout the RPM range.
Q: Will a performance exhaust void my vehicle warranty? A: Under the Magnuson-Moss Warranty Act, manufacturers cannot void warranties simply for installing aftermarket parts. However, if a modification causes damage to other components, related repairs may not be covered. Our exhaust systems are designed to work within OEM parameters and include comprehensive installation documentation to protect your warranty coverage.
Q: What’s the difference between cat-back and turbo-back exhaust systems? A: Cat-back systems replace everything from the catalytic converter to the rear of the vehicle, offering moderate performance gains and easier installation. Turbo-back systems replace the entire exhaust from the turbo outlet, providing maximum flow improvement and power gains but requiring more complex installation and potentially affecting emissions compliance.
Turbo and Forced Induction
Q: Can I install a turbo kit on my naturally aspirated engine? A: Yes, but it requires comprehensive engine preparation including forged internals, fuel system upgrades, and ECU tuning. Our complete turbo kits include all necessary components: turbocharger, intercooler, piping, fuel injectors, and engine management. Installation typically requires 20-30 hours and professional tuning for optimal performance and reliability.
Q: How do I choose the right turbo size for my application? A: Turbo sizing depends on your power goals, engine displacement, and intended use. Smaller turbos (GT2860RS) provide quick spool and excellent street drivability but limited top-end power. Larger turbos (GT3076R) offer more power potential but with increased lag. Our technical team provides detailed turbo selection consultation based on your specific requirements.
Suspension and Handling
Q: What’s the difference between coilovers and lowering springs? A: Lowering springs work with your OEM dampers to reduce ride height and improve handling, offering a cost-effective upgrade with moderate performance gains. Coilovers provide complete suspension replacement with adjustable ride height, damping, and often camber adjustment, delivering maximum performance customization but at higher cost.
Q: How low can I safely lower my vehicle? A: Safe lowering depends on your vehicle’s suspension geometry and intended use. Generally, 1-2 inches maintains good drivability and suspension travel. Our suspension kits include recommended drop ranges: Comfort (0.8-1.2″), Sport (1.2-1.8″), and Track (1.8-2.5″) configurations with corresponding spring rates and damper settings.
