Help Your Engine Breathe Better

Automotive experts have boiled an engine down to being nothing more than a big air pump, stating simply: the more air you pump through an engine at one time, the better it performs.

That’s the reason for installing turbochargers or superchargers, to cram as much air as possible into the engine as quickly as possible. Of course air “intake” is only half the battle. You must also have proper “exhaust” with the right amount of “back pressure” to realize the maximum benefits of a better breathing engine.

Once an engine has inhaled and burned the air and fuel mixture, it needs to exhale to eliminate the “spent gases.” This is where your exhaust system comes into play. From the cylinder head, the exhaust gas travels into an exhaust manifold (or two on V6, V8 and V10 engines). Many of these “factory” exhaust manifolds become restrictive if you increase airflow into the engine with a performance air filter and a cold air intake—and some are restrictive even before you make any performance enhancements.

The cat-back system for the 2006-2007 Corvette ZO6 7-liter V8 is a true 3-inch system made of T-304 stainless steel with smooth CNC mandrel-bent tubes and straight-through, S-style, race-bred mufflers. The system flows more than 100 cubic feet per minute (CFM), better than the OE system while generating 24 more horsepower and 24 lb.-ft. of torque on a stock engine. Million-mile warranty.

Cat-back exhaust system for the Chrysler 300C SRT8 features patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement and fuel economy. Each system is built from premium aircraft-quality T-304 stainless steel to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow and power, and precision computer-controlled CNC manufacturing ensures an accurate fit. Million-mile warranty.

The solution to passing gas better is simple: add a high-flow exhaust system consisting of high-performance headers and/or high-performance mufflers and exhaust. There’s an immediate horsepower and torque improvement achieved by installing these products, along with a cool look and better sound.

Some designs even have a “scavenging effect,” which means they help pull the exhaust gases out of the combustion chambers, so your engine can fit more fresh air and fuel in for the next combustion cycle to make even more power.
