FAQ

Will these headers fit my 2005 Chevrolet Silverado?

Yes. The Flowtech Shorty Headers are designed as a direct replacement for the factory exhaust manifolds on Chevrolet Silverado models, including the 2005 year, and they accommodate all standard emission components.

Do I need to modify my exhaust system after installation?

No additional modifications are required. The headers bolt directly to the existing exhaust ports, and the included flanges connect to the stock exhaust piping without the need for custom work.

Are these headers legal for street use in all 50 states?

Absolutely. They carry the C.A.R.B. EO #D‑115‑16 certification, which meets the emissions standards for street use across all states.

What is the expected increase in horsepower?

While individual results vary based on engine condition and supporting modifications, most users report a modest gain of 5‑10 hp due to improved exhaust flow and reduced back‑pressure.

How do I maintain the headers to ensure longevity?

Regularly inspect the flanges for tightness and clean any carbon buildup with a non‑abrasive cleaner. The stainless‑steel construction resists corrosion, but periodic checks will keep performance optimal.
