Transform the sound and performance of your Porsche 997.2 with the CARGRAPHIC Sport Rear Silencer Set featuring integrated PLO (Pressureless Open) exhaust valves. Engineered and manufactured in Germany, this premium performance exhaust system delivers enhanced acoustics, improved throttle response, reduced backpressure, and increased power while maintaining exceptional everyday drivability with no unwanted drone or resonance.
Designed for drivers seeking a sharper, more aggressive Porsche exhaust tone, the CARGRAPHIC Sport Rear Silencer Set produces a deeper low-frequency sound at cruising speeds while delivering a crisp, volume-enhancing motorsport character under acceleration and higher revs.
The absorptive silencer design combines CNC mandrel-bent pipework with lightweight SS304L stainless steel construction for maximum flow efficiency, durability, and reduced system weight. The specially produced concave domed end baffles optimise both sound quality and structural stability.
This system is compatible with original Porsche tailpipes or CARGRAPHIC sport tailpipes. Vehicles fitted with factory Porsche Sport Exhaust (PSE) tailpipes require the optional adapter set (Part No. CARP97DFIPSELP).
Dyno-tested performance improvements of up to 7kW (10PS) and 10Nm of additional torque help improve throttle response, freer revving characteristics, and overall engine performance.

These simple U/J pipes remove the mufflers that are tucked up in the rear quarter panels. Why the reason for these I do not know. Typically in the past we either see a main centre muffler or 2 mufflers with catalyst pipes. So this was the first simplest part to change out. Keeping the same diameter for a perfect OEM replacement, these pipes are straight through which not only eliminates any muffler packing or baffling, but also the weight. Each stock muffler weighs approximately 15.6lbs. The Designtek Secondary Exhaust Muffler Bypass Pipes are about 3lbs each. Now eliminating restriction, we have also saved about 25lbs off the rear end. Because this part still retained the factory headers with cats and the factory center muffler, it added a slightly deeper tone to the exhaust but not a drastic droning change that a full exhaust could. Upon revving the car out stationary and on the dyno, you could hear the tone change nicely as you past the 4000rpm mark.
Garage Notes: The pipes sometimes rub on the heatshields causing a resonation through the car. This can be sorted by redressing the heatshields but isn't a straight forward bolt up and go replacement.
The sound its self is quite impressive and very sporty from the outside but to drive causes a pretty bad droning sound under normal driving conditions. This exhaust peaks at 101decibels
According to the factories dyno test, the secondary muffler bypass pipes really start achieving performance from 3700rpm all the way to redline. With a baseline test in 3rd gear and all wheel drive (have to for the dyno and no warning lights), the car made 344HP and 289ft/lbs of torque. Based on the ambient temperature, the factories Mustang Dyno, and 91octane fuel, this is about right considering the car comes with 400bhp. With the addition of our pipes, the car put down 358HP and 298ft/lbs of torque gaining 14HP and 9ft/lbs at the peak.
