Frequently Asked Questions
Straightforward answers about pricing, warranties, diagnostics, and repairs.
How do pricing estimates work?
We believe in absolute transparency. We provide clear, upfront estimates after a physical inspection, backed by photos so you see exactly what we see. For custom exhaust and welding, we quote based on specific materials and build complexity. No hidden costs, no surprise fees.
What warranties do you offer on parts and labor?
We stand by our precision service with a nationwide 2-year/24,000-mile warranty on most parts and labor.
Whether you charge for diagnostics?
We offer free, transparent preliminary inspections. Our team performs a multi-point visual check and provides photos of any recommended repairs or preventive maintenance. While we include a general assessment at no cost, please note that advanced diagnostics for check engine lights, electrical systems, and complex computer issues are billed separately.
How long do common repairs take?
General maintenance and muffler replacements are often completed the same day. Major custom fabrication or specialized part orders may require 1-3 business days to ensure the highest quality results.
Whether you work on all makes and models?
Yes. While we are exhaust specialists, we provide dealer-alternative mechanical service for all Domestic, European, and Asian makes and models, utilizing certified diagnostic equipment for every vehicle.
