  1. Wicked sound! 5 Star Review

    Posted by on 23rd Feb 2017

    Cannot say enough great things about the team over at Fabspeed!

    They were a pleasure to work with, covered all the details, and were eager to meet my deadlines. Product was well packaged, and quality was outstanding. Everything fit right up, and the first start-up will be a day to remember! Makes me fall in love with the flat-6 wail all over again. No need for me to upgrade to the 991.2 anymore! :-)

Product Description

Increase power and save weight with a slightly throatier and deeper exhaust note throughout the RPM range; And upgrade your Carrera with our Deluxe Quad Style Tips for a more aggressive and refined look.  

The 991 Carrera Maxflo Performance Side Exhaust replaces the factory side mufflers, improving the exhaust flow and the overall power while providing a deep and throaty sports car sound.  This system can be used with the OEM outlet tips, or can be upgraded to include Deluxe Quad-Style Tips.

Fabspeed recommends using these Side Mufflers in conjunction with a Center Muffler Bypass X-Pipe for non-PSE equipped cars. There is not a significant sound advantage to using these Side Mufflers alone in conjunction with the factory non-PSE center muffler.


  • Fits all Porsche 991 Carrera vehicles (2012-2016)
  • Designed to be compatible with factory/OEM headers and center muffler (NOTE: Please call/contact us if you're interested in combining this system with additional Fabspeed exhaust components.)
  • Saves 1 lb versus the factory components
  • Improves sports car sound and power throughout the RPM range; 15 whp and 11 ft-lbs of torque
  • Constructed from high-quality 14-16 gauge C.N.C. mandrel-bent T304L stainless steel for optimum flow and maximum durability
  • Direct bolt-on replacements for the factory side mufflers
  • Compatible with Fabspeed's Deluxe Quad Style Tips in your choice of finish; also compatible with factory OEM tips
  • Backed by Fabspeed's Lifetime Warranty
