DesignTek 996 Performance exhaust package. High Grade stainless steel exhaust system for Porsche 996 1998-2004.
Made from 14 - 16 gauge T304 stainless steel.
Includes Sports Exhaust and Sports Cat bypass pipes, really feel and superb sports car sound.
NOTE: In the United Kingdom, sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001. They are not MOT compliant and cannot be used on public roads. These components are intended solely for race and track use.
For vehicles manufactured before 1st March 2001, a non-type approved sports catalytic converter may be fitted, provided it offers comparable performance to the original and the vehicle continues to meet the applicable emissions standards for its age. The vehicle must still pass an MOT test.
If you are located outside the UK, please check your local laws and regulations to ensure compliance.

The OE Match Rear Exhaust Mounting Kit is a complete hardware set designed to replace worn or missing mounting components for the rear exhaust system on the Porsche 997. It includes the essential rubber hangers, brackets, bolts, and insulators needed to restore proper exhaust support and alignment.
Fits:
Porsche 997 3.6L-3.8L 2005-08 (not Turbo/GT2)
Kit included:
2x Pipe Connector, 55x58.5x75mm, stainless steel
2x Bolt, M8x1.25x140mm
2x Bolt, M8x1.25x70mm
4x Lock nut, M8x1.25
This product is a comprehensive OE Match rear exhaust mounting kit for the Porsche 997 family. Over time, exhaust mounting rubbers, brackets, and associated fixings can deteriorate due to heat cycling, vibration, and exposure to corrosive elements. This kit brings together all the normal wear components in one package, allowing a complete refresh of the rear exhaust support hardware.
Each piece in the kit has been selected or engineered to match the dimensions, materials, and load-bearing characteristics of the factory parts, ensuring correct exhaust position and reduced risk of sagging, rattling, or detachment.
Over time, rear exhaust mounting components can:
• Harden, crack, or split due to age and heat
• Corrode and weaken under road salt and moisture exposure
• Stretch or deform, allowing excessive exhaust movement
• Loosen, causing rattle, vibration, or exhaust contact with bodywork
Failing mounts can lead to:
• Exhaust system sagging
• Unwanted noises
• Metal fatigue or cracking
• Reduced ground clearance
Installing a complete OE Match rear exhaust mounting kit restores proper support, improves NVH (noise, vibration, harshness), and helps prolong the life of the exhaust system.
When to replace. Install this kit when:
• You notice exhaust sagging at the rear
• There’s excessive vibration or noise from the exhaust area
• Exhaust hangers show visible wear, cracking, or separation
• You are replacing or removing the rear exhaust system
• You’re performing a comprehensive underbody service
