The Porsche 996 is an easy car to make power with. However, you need to choose the correct products to gain performance properly. Agency Power has designed this muffler system for the Porsche 996 to give your car a great sound and add over 10 wheel horsepower! Tested in proper conditions on a Mustang Dynamometer, this exhaust system repeatedly added horsepower to our stock 996 Carrera.
Porsche owners desire an exotic sports car sound with improved power. When you bolt on the AP Mufflers, you get better throttle response with the reduced restriction. The car will scream at the high RPM�s, yet have no droning sound while at cruising speeds. The Agency Power muffler kit is made from 321stainless steel. The entire system is polished. This system saves almost 15lbs over the factory mufflers! Factory tips and aftermarket tips can be used with this system. It fits with all factory hangers and mounts up to the factory or aftermarket cat pipes. Mufflers fit all Porsche 996 Carrera vehicles from 1999-2004.
Combined with our Agency Power Porsche 996 headers, this car made 15 wheel horsepower!

Wait a second... The wheel horsepower on a 3.4 liter is 222? That is a 25% drivetrain loss! I thought the loss in my 968 was in the 'teens and the 911 design (with the engine right on the transaxle) was much less. Is this correct?
That would mean I am getting about 243 whp on my 3.6 liter. That just seems low.
Any insight on here?
Thanks.

we use a Mustang 500 AWD Dyno. Car was done in 2wd mode. This is a debate I wont get it to on dynos. look at the before and after. Will the mufflers last... oh yes they will. Quality of material, type and construction. Most of your Porsche "tuners" systems are made overseas now from the same factory, they just put there stamp on them. We know....
