Product Description:
CARGRAPHIC GT Sport Exhaust System Backdate with exhaust valves Center outlet 2x70mm GT3 Look SS304L

Consisting Of:

• 2x CARGRAPHIC ID42 GT manifold set with ID 42mm primaries and enlarged 2,5" / 63,50mm flared end collector boxes
• CARGRAPHIC link pipe set with / without 2x200cpsi Ø110mm HF catalytic converters, with heating Ø130mm and integrated exhaust valves pressureless closed (PLC)
• CARGRAPHIC 4>2 flow sport rear silencer with center outlet tailpipes 2x70mm GT3 Look
• Adapterset heater hoses
• Fitting kit including gaskets and bandstraps  

   

SOUND / SUPER SOUND EXPORT Version
NO DRONE OR RESONATION even in combination with other CARGRAPHIC exhaust components fitted.

Key Features & Benefits:

• Absorptive silencer design dual flow with bypass and CNC mandrel-bent pipework
  
• Two silencer versions for backdate rear valances available.
• Wide version with big volume 212 x 131 x 700mm and a narrow version with small volume 203 x 102 x 700mm for limited fitting space.
• Fully 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.

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.
