Product Info
2001-2007 Chevy Full Exhaust System is a truck-specific exhaust option for the application shown in the title.
Confirm the listed year, make, model, engine, and any truck-specific configuration before purchasing. Review the available Matieral, Size, Truck Configuration selections before ordering. The exact contents and fitment depend on the options selected on this product page.
How to Choose Your Options
- Exhaust size: 4-inch and 5-inch identify the nominal tubing diameter of the selected exhaust configuration.
- Material: Aluminized steel is the standard coated-steel exhaust material and the lower-cost choice. T409 stainless steel is the corrosion-resistant upgrade; it can still develop normal surface discoloration or oxidation over time.
- Truck configuration: Standard/Regular/Normal Pickup is for a factory pickup-bed chassis. Cab Chassis/Incomplete Truck is for a chassis-cab or incomplete-vehicle configuration that receives a separate work body or bed and may use different wheelbase and exhaust routing. Select the actual vehicle configuration, not only the cab style.

Just like all of Flo-Pro's/Jamos Exhaust kits, it will come with all the required clamps, pre-weld contour bent hangers, and stronger flanges to help you sail through the installation process.It not only sounds great but will also improve mileage, torque, and throttle response.
