Fabspeed Muffler Bypass Pipes for 997 Porsche 911 Carrera / S
Enhance the rear of your vehicle by shedding weight and infusing an aggressive exhaust note. Achieve this by substituting the bulky factory mufflers with straight-through tubes that fully replace them while retaining the original Porsche tips. This modification yields substantial power gains throughout the power band. It delivers impressive mid-range torque for a dynamic street driving experience and heightened top-end horsepower for track performance. Dyno results, as depicted in the photos, reveal a notable increase of 21 whp and 21 ft/lbs of torque.
Features
- Increase horsepower and torque by 21whp and 21ft-lbs
- Saves 31 lbs from the rear of the vehicle for much better handling
- Simple DIY bolt-on installation; no cutting or welding required
- Comes with all hardware necessary for a do it yourself installation
- All Fabspeed performance products are backed by the Fabspeed lifetime warranty

Frequently Asked Questions
- Does this fit the Carrera 4 or Carrera 4S?
No. This kit is designed specifically for the 997 Carrera and Carrera S (2005-2008, rear-wheel drive). Fabspeed does not list Carrera 4 or Carrera 4S fitment for this part, and it isn’t offered in those variations. - Can I run these bypass pipes with a PSE (Porsche Sport Exhaust) equipped car?
No. Fabspeed states these pipes are not compatible with PSE-equipped exhaust systems, since they replace the factory muffler housings the PSE valves are built into. If your car has factory PSE, this isn’t the right product. - How loud is it, and is there any drone?
Expect a loud, aggressive sports-car exhaust note — that’s the point of a straight-through bypass pipe. Fabspeed’s own documentation notes some interior drone at cruising RPM, so this is a trade-off worth knowing about before you buy, not a hidden downside. - What performance gains can I expect?
Fabspeed states +21whp and +21ft-lbs of torque gained across the power band, along with a 31 lb weight reduction from the rear of the vehicle versus the stock mufflers. - Is installation difficult?
No — it’s a straightforward DIY bolt-on job. No cutting or welding is required, and all necessary hardware is included in the kit. - Does it come with a warranty?
Yes, it’s backed by Fabspeed’s Lifetime Warranty against manufacturing defects.
