JBA Aluminum Exhaust Chevy Silverado 4.3 4.8 5.3L RC SB 02-05

If you own a Silverado or Sierra, chances are you use it for towing or hauling. You probably know what its like when the hill is steep and your V8 is running wide open to keep up with traffic. JBAs Evol exhaust systems give the small block engine under your hood a less restrictive path to expell spent gasses freeing up extra ponies. This is often times the easiest way to increase horsepower and torque on your truck. Each system is engineered and tuned to deliver maximum performance gains throughout the RPM range without annoying interior resonance.These JBA kits feature 3 mandrel-bent tubing, a fully welded high flow JBA muffler, factory style exhaust hangers, and a great looking 3-1/2 polished and chrome plated stainless steel rolled tip. Power. Sound. Quality. JBA has it all.
