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.

Sometimes, you just gotta have the best of everything. When it comes to flow, you can't get much better than Pypes Race Pro mufflers. They feature a 'straight-through' exhaust flow path. Their throaty sound is surprisingly tame, considering the absence of any impedance when you look down their barrel. At idle and low-rpm cruising, you will not draw much attention, but upon acceleration, bystanders look out! The Race Pros' aggressive sound is the result of applying a layer of stainless mesh around a unique internal perforated tube, accompanied by a healthy stuffing of basalt insulation before the unit is sealed. Pypes Race Pro mufflers are highly recommended for the track, where every 1/10th counts. Of course, there are plenty of these mufflers hidden under some fine street machines, too. Think of these mufflers as large inhalers for your car.
