awakeinAZ Posted April 17, 2011 Report Share Posted April 17, 2011 Ok, thanks! They seem to get a bit louder after some drive time. I have the same ones. Those are also known as the KR mufflers. Link to comment Share on other sites More sharing options...

They make the car sound the way it should have from the factory. I grin everytime I start it, with a large amount of credit going to these mufflers!

Cobra 29 Posted April 18, 2011 Report Share Posted April 18, 2011 I swapped in a pair of FR GTB mufflers because I had them. The muffler tips are like the FR500s and look much better than stock. The sound is deeper. I hope they are less restrictive than the GT500 stock mufflers. Link to comment Share on other sites More sharing options...

moody03svt Posted April 20, 2011 Report Share Posted April 20, 2011 how to these compare to the Ford Racing sport and touring mufflers? are they the same or close to the Ford Racing Sports and l would think louder than the Ford Racing Touring ones?

Whammer Posted April 20, 2011 Report Share Posted April 20, 2011 Add the KR H pipe, or the H pipe from Powerhouse Racing (basically the same as the KR) and you will not believe how much better it will make those mufflers sound. It's like old school muscle car sound!!! Link to comment Share on other sites More sharing options...

It's like old school muscle car sound!!! My GT500 has an x-pipe already installed. This looks to be stock. Does the H-pipe provide more flow or power, or just a deeper sound? I need to find the KR or Powerhouse Racing H-pipe to review. Thanks, Cobra 29 Link to comment Share on other sites More sharing options...

Sounds like the H pipe adds a deeper sound. What rear mufflers are you running in the video? Cobra 29 Link to comment Share on other sites More sharing options...

Cobra 29 I've got the KR's on it. The H pipe adds a burble sound to the mufflers- which I think is a 60's muscle car sound. Absolutely no drone at any speed.
