Key Features & Benefits:

• CNC mandrel-bent pipeworkFully made from SS304L lightweight stainless steel
  
• High performance components, dyno tested
• OE / factory heating system retains full functional
  
• Olive-/ Bandclamp- and sleeve connections enable easy installation and perfect adjustment
• Collector boxes and silencer inlet flanges positioned max to the outside to achieve max possible clearance to valve covers, because of heat radiation.
• Reinforced laser-cut brackets
• Reduced backpressure due to freer flowing
• Reduced operating temperature
• Maximized performance
• Improved throttle response, freer revving
• Improved enhanced acoustics with no drone, resonation or vibration
• New designed Ø2,5" / 63,50mm exhaust flaps are pressureless closed (PLC) which means the car will start quietly (whereas the ordinary version needs intake vacuum to close the flaps which always takes quite some time and can be annoying)
• With flaps closed the gases flow, via the bypass pipes, silenced through the final silencer, whereas with flaps open most of the gas stream flows freely through a second exit within the tailpipes.
  
• The sound is reminiscent of the famous and legendary RSR`s, simply breath taking!
• Model specific tuned sound still in keeping with the Marque
• Weight reduction            

Why Choose This Exhaust System?
The original exhaust on older 964 models can be restrictive in flow, heavy, and produce a muted sound. Switching to this CARGRAPHIC system unlocks the engine’s full potential: better exhaust flow, sharper throttle response, more pronounced exhaust tone, and improved performance — all while retaining reliability and proper fitment. It’s an ideal upgrade for enthusiasts seeking classic 964 sound and performance without resorting to race-only systems.
