MagnaFlow Sys C/B GM 1500 Ext Cab S/B 4.8L/5.

If you're looking to give your 1999-2002 Chevrolet Silverado 1500 a more aggressive sound and improved performance, this Magnaflow Street Series cat-back exhaust system is a solid choice. It's designed to replace your factory exhaust from the catalytic converter back, giving your 4.8L or 5.3L engine a distinct, powerful tone that's noticeable without being overwhelming inside the cabin. This system aims to bring out the personality of your truck, making it sound as good as it looks.

Magnaflow builds this system using durable, corrosion-resistant stainless steel, ensuring it holds up well over time. The main piping is a full 3 inches in diameter and features mandrel bends, which means the pipe's diameter stays consistent throughout the bend. This design helps the exhaust gases flow more freely, contributing to the dyno-proven performance gains Magnaflow claims. The system exits in a dual split rear configuration, finished off with 3.5-inch polished stainless steel tips that have a rolled edge and a clamp-on design for a clean look. The use of CNC precision robotic manufacturing techniques helps ensure a direct-fit installation, meaning it should bolt up to your truck without major modifications.

This cat-back system is designed for a direct fit, making installation more straightforward. It comes with everything you need to replace your stock exhaust from the catalytic converter back, including the mufflers and the rear exit piping with tips. Magnaflow backs this system with a 1-year limited finish warranty and a limited lifetime construction warranty, giving you peace of mind with your investment.
