2003-2007 Chevy/GMC 1500 Classic 4.8/5.3L EC/CC-SB Cat Back, Single Side, AL by MBRP
P Series from MBRP brings you the best of both worlds. Designed and constructed to the exact same specifications as MBRP's Pro Series you can expect the same improvements in torque and horsepower and the same awesome sound as our top of the line products. The difference is the heavy duty aluminized steel construction. You save money without compromising on performance. MBRP Installer Series truly is superior to other aluminized exhaust products on the market. Heavy sixteen gauge steel is one reason. Another is that our systems have a thick protective coating of aluminum silica on the seams - an area that is often left exposed to rust. We are so certain of our Installer Series products that we back them with an industry leading 3 Year Warranty.
