Looking for the most aggressive sound in the Flowmaster muffler line? Then take a look at their 40 Series mufflers. Designed for use on street and strip vehicles, they take the sound waves produced in the exhaust, and cancel them against angled baffles built into the muffler case. This improves both horsepower and fuel economy. Best of all, they allow you to hear that cool Flowmaster tone inside of the vehicle, as well as outside. So, if you want more power and less noise, then you've got to get Flowmaster 40 Series mufflers.

There's no reason why you can't give your sport compact a major power boost using the same sort of technology that the V-8 crowd has been for years. NOS has taken care of that with their Sport Compact nitrous-oxide systems. They can turn your mild-mannered ride into a fire-breather with a quick shot of 40-75 extra horsepower, with a dry system, or an even wilder 50-150 extra ponies with a wet system. The latter types are especially helpful to supercharged and turbocharged engines, which generate heavy doses of unwanted heat in the intake system. Kits come complete with the mounting brackets, nozzle, stainless-braided hose, fittings, jets, wiring, switches, and mounting hardware. Available with and without nitrous bottles.
