  1. Excellent Upgrade! 5 Star Review

    Posted by on 14th Feb 2018

    Incredible difference in sound-the way a flat-six should sound! Very easy installation, (after discovering which 3 bolts to remove). Wife doesn't dig-but that is why she has her Merc. Although not a huge weight reduction in rear end, (approx 35-40 lbs), car seems to handle a bit better. Performance in low end better with increased torque and hp.
    Very loud-but that's why I did it!
    Highly Recommend!


  2. Best upgrade...period! 5 Star Review

    Posted by on 4th Feb 2018

    Just installed yesterday on my 2004 996 Targa-WOW! Instantly the car sounded like a proper 911 should. The snarling, throaty, revving sound immediately changed every aspect of the car. Very glad I installed, (yep-your wife will be pissed, but hey you didn't buy the car for her anyway now did you?).
    Fabspeed should actually include directions to show WHICH 3 bolts to remove-this would have saved me over an hour of installation time. Job is quite easy and you mDO NOT HAVE TO REMOVE BUMPER!


  3. Great value purchase 5 Star Review

    The best review for this product was the look on the face of the GT2 owner that sat next to me at the red light.

Porsche 911 Muffler Bypass Sound Comparison - Fabspeed Bypass Pipes Vs Standard Mufflers (03:30)
Sound comparison of a 996 Porsche 911 Carrera with Fabspeed muffler bypass compared to a factory muffler.

Product Description

Lighten the rear of the vehicle while adding a very agressive Supercup-style sound by replacing the heavy factory mufflers with straight-through tubes                                    

NOTE: This is a very loud and aggressive exhaust system. We love it, but your wife/girlfriend/neighbors probably won't! If you're looking for maximum sound and performance, you've found it. If you are looking for a more subtle and daily-drivable upgrade, we recommend checking out the Maxflo Performance Exhaust or the Supercup Exhaust System.

FEATURES:

  • Fits all Porsche 996 Carrera vehicles 1998-2004 (Model Specific)
  • Improves horsepower and torque by 23 whp and 45 ft-lbs
  • Saves over 35 lbs from the rear of the vehicle!
  • Used by many Rolex Grand Am race teams as well as PCA/POC and HPDE drivers
  • Simple DIY bolt-on installation; no cutting or welding required; easy to do at home in the garage
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
