Note: 409 stainless exhaust material is titanium stabilized ferritic stainless steel. 409 stainless is used in applications where appearance is a secondary consideration to mechanical properties and corrosion resistance and where some weldability is required. An example of 409 stainless usage is catalytic converter assemblies. 409 stainless has excellent forming characteristics and is rust through resistant. A surface rust will form in most instances. This rust retards further corrosion.

  1. No Drone 5 Star Review

    Posted by on 18th Oct 2016

    An excellent product, perfect fit and the sound was exactly what I was looking for. I did not want it to sound like Cheery Bombs behind a set of headers. The sound is amazing and it has absolutely no drone!

  2. great sound 4 Star Review

    Posted by on 15th Sep 2014

    The sound is great. It is much more aggressive than the bullitt mufflers. The alignment is not perfect even after some adjustment. Low rpm cruising is much cooler.

  3. Just awesome 5 Star Review

    Posted by on 2nd Aug 2014

    I just put these on my '07 Shelby GT, had to replace the mufflers due to a rattle, and the GTA's aren't available anymore. I am glad i stuck with Ford Racing and chose these, what a great sound. I installed these at my work so it was only about 30 minutes with a rack. Fitment is excllent, just like it was aligned at the factory. As far as the sound, it's sounds bad a$$. After i fired it up i had people coming to see what sounded so good from over 50 yards away, it sounds that good, and there's no drone at all at any rpm. I highly recommend.

  4. THE axle back mufflers for S197 5 Star Review

    Posted by on 23rd Jun 2014

    The fact these are the EXACT factory correct fit is a huge thing, from the exact same OEM type welded on clamps to the slot for the alignment pin, they are perfect. That was really nice and made them easy to install. The fact they are the best sounding exhaust I have heard on a Mustang is what I was hoping for and got. There is no sound clip that do them justice, there is a depth that is not getting recorded that is perfect. If you are cruising they are fairly quiet, but WOT it just rips.

  5. Best Sound for a GT500 5 Star Review

    Posted by on 4th Jul 2013

    I was looking to get a more aggressive tone than my FRPP M-5230-GTA mufflers on my 2007 Shelby GT500. These mufflers definitely did the trick! Perfect sound, no drone, and quiet when you want it to be! I recommend pairing with an H-pipe to get the perfect GT500KR sound.

  6. Best Muffler Setup for s197 5 Star Review

    Posted by on 6th May 2013

    Had several exhaust on my 2007 Mustang GT and these are the best by far. No Drone and the sound is amazing. I have high flow catted h pipe and it screams above 4000 rpm!

  7. Just the sound I was looking for 5 Star Review

    Posted by on 2nd Mar 2013

    I was looking for a more aggressive tone for my 2008 Shelby GT. These fit the bill perfectly. They do not come with instructions but install was easy taking about 45 minutes. I am very happy with the purchase and recommend them.

  8. Awesome for V6 Dual Exhaust! 5 Star Review

    Posted by on 3rd Sep 2012

    Purchased a pair of fr500s mufflers to install on my 06 v6 mustang. They have a great rumble and sound excellent at any rpm. Loud when you get on it but quite when you want it to be and NO DRONE. Highly recommend!!!

  9. Excellent Muffler Upgrade for Shelby GT (GTA mufflers) 5 Star Review

    Posted by on 9th Jul 2012

    I installed these mufflers myself in about 1 1/2 hours in my garage one evening. The hanger rods fit just on the end of the hangers, and everything bolted up perfectly. The only problem that I encountered was that the muffler clamp bolt sheared off when I was torquing down with the Torque rench

  10. Perfect 5 Star Review

    Posted by on 25th Apr 2012

    I was looking for something more than stock but not so loud to be obnoxious. I think I found it! Just got them on today and really like them. Not too loud if you drive easy; but a great rapp if you get on it. (no drone !).
