Designed to be a direct replacement for the restrictive factory muffler, this X-pipe exhaust will bolt up to stock exhaust components, including the oval tips, for an easy install and easy power, all while livening up the sound to give the 991 a more exotic growl.

The exhaust was tested on a Porsche 991 Carrera S with the stock headers and secondary mufflers mated to the new center X-Pipe exhaust. The baseline of the car has a very waivy ride through the RPM band. From 3000rpm to 6400rpm the car made consistent power. From 3800-4200rpm the car made huge gains of torque! The rest of the curve yielded about a 20hp gain until it ran out of steam near redline.









Here is a video one of our customers sent us ripping through Laguna Seca with his Agency Power X-pipe equipped carrera



PM for more information and 6speed pricing.

 

What is the approx installation cost?
Jim

 

Install is about 2-3 hours on this. Will PM pricing for the exhaust

 

PM to liven up the sound and power of your 991!

 

Normally installing an x-pipe only means removing the center muffler and you don't have to take off the bumper - it's less than an hour. Are you talking about taking off the side mufflers as well?

 

Another recycle of the 20 hp gain myth . I suppose with PSE it's a 30 hp gain.

 

Behold, the almighty dyno

 

Like the video-and the driver is pretty darn smooth around LS...Nice work. However not sure of the estimated 2-3 hours labor though....Seems lengthy for removing the center rear muffler. What else is involved?

 

Last couple days of the month! PM for steep discounts!

 

Always offering discounts for AP parts, send a PM for more info

 

You expect me to believe that this muffler delete adds something like 85 ft-lbs of torque around 4000 rpm? And that it loses no torque anywhere in the rev range?
