Improve your exhaust flow by 23 percent with Hooker Aero Chamber mufflers. These mufflers are designed to do much more than simply muffle exhaust noise; they produce a deep throaty rumble that will not change--ever! Plus, Aero's aerodynamically designed chambers flow better to deliver more horsepower and torque thanks to Hooker's unique step principle. The stepped acceleration chamber increases exhaust gas velocity for maximum flow. An aerodynamic lens directs sound pressure into and out of the muffler while resonance chambers and sound absorption chambers create the sound. And, to keep Aero Chamber mufflers from rusting from the inside out--a stainless steel perforated plate to eliminate internal rust. Muffler cases are available in 16-gauge aluminized steel or stainless steel but it's truly what's inside that makes it so sophisticated. Need a muffler? Go with Hooker Aero Chamber mufflers--the real master of flow!

Look great, but quite heavy, and have "CHINA" stamped on them. Difficult to weld for some reason. Much quieter than one would imagine, sound ok at idle, but a bit flat and featureless at WOT. As these were fitted to a stock small block, the performance advantages were not apparent, but local racers rave about them. Not the best choice for someone with a mild engine wanting to make some noise, but apparently THE choice for big power on the street. ...read more
