Making your pickup's exhaust note deeper, fiercer, and wilder, piling on a few more horsepower and ft-lbs of torque, Silverado exhaust systems come in many layouts from America's finest, most experienced aftermarket companies. Full-scale 1999-2006 Silverado 1500 exhaust systems – cat-backs that replace everything from just behind the catalytic converter all the way to the end of the tailpipe – are super popular among pickup drivers. Among this lineup of components, they offer a complete makeover of the system and its ability to flush out the waste gases of combustion, plus a big increase in style with both their dramatically flared exhaust tips and their changes to your truck's sound. They're built for practicality with mandrel-bent tubing and high-flow mufflers that free up the restrictions on exhaust flow found in stock systems, adding somewhere between +10-20 horsepower and ft-lbs of torque to your available engine power in most cases. In order to suit different budgets, these cat-back exhausts come in aluminized steel, T-409 stainless, and T-304 stainless, each costing more but offering better resistance to rust. The large exhaust tips have a powerful, aggressive look, and may be either brilliantly polished or else coated black for a more stealthy effect. They often have logos or symbols on them for extra style and come in different configurations – single exit, dual split exit, dual side exit, and so forth. The selection of 1999-2006 Silverado 1500 midpipes includes both catted mid-pipes which can be used legally on the road as well as for off-roading, and off-road mid-pipes which omit the catalytic converter and can't be used for street or highway driving. Fabricated with high-flow tubing, these mid-pipes – as their name suggests – fit in between aftermarket headers and an aftermarket cat-back exhaust system. They're built to create the intense flow you need to upgrade the horsepower boosting potential of a reworked exhaust system to the maximum possible. Most are fabricated out of stainless steel of various grades, which ensures they won't rust out from either external splashing or internal condensation on the metal surface. They are mostly engineered for use with long tube headers. The off-road Y-pipes completely eliminate the catalytic converters, which provides the maximum possible boost to hp, torque, and throttle response, as well as developing the strongest exhaust note you're likely to get out of any aftermarket exhaust system, though it also means you can only legally use them on trails and other locations off public roads. In fact, they cannot be used or sold in California for any purpose due to the restrictions imposed by CARB regulations. You can complete the back to front renovation of your truck's exhaust system with 1999-2006 Silverado 1500 headers, which hook up to the engine block at one end and connect to the mid-pipes at the other. These long-tube headers are built very tough, usually from stainless steel, and enhance scavenging of exhaust gases from the cylinders to ensure the engine doesn't get choked up on its own fumes and thus start running less efficiently. American Trucks also carries a variety of other exhaust system parts for Chevrolet pickup trucks so that you can get the exhaust running just how you want it to. You can find 1999-2006 exhaust tips to match your aesthetic preferences, built to fit 2.5", 2.75", and 3" tailpipes, and even other diameters in some instances. These include angled rolled edge exhaust tips for visual interest, straight cut tips for a more brutally simple look, and a choice between mirror polished stainless finish for a bright, eye-catching gleam of reflected sunlight, and a commando stealthy black finish (usually also applied over stainless steel to prevent rusting). There are even carbon fiber wrapped exhaust tips for a unique space-age style. On the technical front, 1999-2006 O2 sensors feed precise data back to your Silverado's engine computer to make sure that the motor is running at its maximum efficiency in terms of both power and emissions. Both upstream and downstream sensors are available for front and rear use. They're built waterproof and tough, and are thoroughly tested to boot. Exhaust accessories for the 1999-2006 Silverado 1500 help you tweak the capabilities of your exhaust system or make necessary adjustments with quality components. Mating flanges with V-band exhaust clamps make it much easier to set up your own custom exhaust system, connecting up sections of pipe with a secure, leak-proof attachment made of mild or stainless steel to match your application. Electronic exhaust cutout systems give you remote, push-button control over an installed cutout, and are built to survive the high heat and other hostile characteristics of the exhaust environment. In short, American Trucks carries everything needed to thoroughly renovate your 1999-2006 exhaust system, whether you're looking to simply replace an exhaust tip or change out the whole system end to end.
