Description
Product Overview
The DynoMax exhaust extension pipe is a high‑performance component designed to replace the factory‑installed exhaust section on 2014‑2018 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. Manufactured by Tenneco under the DynoMax brand, the pipe is forged from 304 stainless steel, providing superior corrosion resistance and long‑term durability in harsh road conditions. With a diameter larger than the original equipment (OE) size and mandrel‑bent bends where applicable, the pipe maximizes airflow, reducing back‑pressure and contributing to measurable gains in horsepower and torque. The part measures 12 x 3 x 3 inches, weighs 1.8 pounds, and carries the OEM part number 51075 for easy reference.
Usage
This exhaust extension is ideal for truck owners seeking a balance of performance and reliability. Whether you use your Silverado or Sierra for daily commuting, weekend hauling, or off‑road adventures, the DynoMax pipe integrates seamlessly into the existing exhaust system. Install it in the under‑carriage area to benefit from the increased pipe diameter and smoother bends, which promote better scavenging of exhaust gases. The stainless steel construction ensures the pipe withstands temperature fluctuations, road salt, and moisture without rusting, making it suitable for all climates.
