siscokid09 Posted November 27, 2014 Report Share Posted November 27, 2014 What kind of exhaust should I put on my GT 500? I put a ford racing power pack on which came with different mufflers and it still isn't loud enough! I don't want to keep buying different mufflers and experimenting.

shel-b001 Posted November 27, 2014 Report Share Posted November 27, 2014 Just add the KR mufflers, I have found after a year they are little louder since I put them on , but no drone. at highway speeds. Link to comment Share on other sites More sharing options...
vandy09 Posted November 28, 2014 Report Share Posted November 28, 2014 Depends on how loud you want it, and what state you live in. Have you thought about just adding a cat less mid pipe? Link to comment Share on other sites More sharing options...
Andrew DeSpirito Posted November 28, 2014 Report Share Posted November 28, 2014 I'll add another vote for the KR exhaust. THE perfect sound for this car. Add the H-pipe if you want to replicate the KR exhaust note in its entirety. (I haven't yet, because the KR mufflers with our stock X-pipe sounds good enough to me.)

takoarm Posted November 29, 2014 Report Share Posted November 29, 2014 I added the Borla Touring Exhaust that is in the clearance section and I love it. Link to comment Share on other sites More sharing options...
FiaCobra Posted November 29, 2014 Report Share Posted November 29, 2014 I had a stock 2008 GT-500 and I replaced the stock mufflers with the "loud mouths" (pretty much a straight pipe) The sound was amazing. Link to comment Share on other sites More sharing options...

BulletPROZ Posted November 30, 2014 Report Share Posted November 30, 2014 Why would anyone buy anything g other than a KR? It is the best sound on this car. Unless your looking for something obnoxiously loud... KR exhaust would be best Link to comment Share on other sites More sharing options...

mavisky Posted December 1, 2014 Report Share Posted December 1, 2014 Another vote for KR here. Borla and Pypes both droned so bad I had them off the car within 10 miles. Link to comment Share on other sites More sharing options...

08KR525 Posted December 2, 2014 Report Share Posted December 2, 2014 I have a KR and wanted something a little louder, so I ended up with the Shelby/MRT's muffler deletes. The car is not obnoxiously loud but definitely let's everyone know it's not stock. There is no drone at speed either. Link to comment Share on other sites More sharing options...
siscokid09 Posted February 18, 2015 Author Report Share Posted February 18, 2015 Thanks for all your answers. Does anyone know the part number for the KR mufflers? Has anyone heard a 2014 Roush stage 3 ? How do the the KR mufflers compare in loudness to the stage 3? Thanks again! Link to comment Share on other sites More sharing options...
skiph Posted February 18, 2015 Report Share Posted February 18, 2015 I ordered mine from Blue Oval Industries a WHILE ago. Best ~$500 I spent and piece of cake (if you have an extra joint in your forearm) to put on http://www.blueovalindustries.com/ex1810.htmlWould have to dig through some things put away for winter to pull the actual Ford part number off of the box to confim is matches the Manufacturer Part Number on the web site Link to comment Share on other sites More sharing options...
oldlugs Posted February 18, 2015 Report Share Posted February 18, 2015 Thanks for all your answers. Does anyone know the part number for the KR mufflers? Has anyone heard a 2014 Roush stage 3 ? How do the the KR mufflers compare in loudness to the stage 3? Thanks again! Also known as the FR500S mufflers: http://www.buyfordracingfromdpm.com/2005-2009-mustang-gt-2007-2009-svt-fr500s-muffler-kit-50-state/ They are a good choice and they don't drone. They even sound OK on the 4.6 cars, but for some reason, more "exotic" on the 4 valve engines. I ran a set on my '08 Bullitt (3V 4.6) for a couple of years, but have since changed to something quieter (Shelby/JBA 4" tip chambered). Link to comment Share on other sites More sharing options...
2007red40thGT500 Posted February 18, 2015 Report Share Posted February 18, 2015 do a google search and you'll find the part number. KR are hands-down the best mufflers for an otherwise stock exhaust on a GT500. period. the end. Link to comment Share on other sites More sharing options...

siscokid09 Posted March 10, 2015 Author Report Share Posted March 10, 2015 Does anyone know the difference between the Ford Racing M-5230-S, the M-5230-SGT, and the M-5230-5GT? Which has better sound quality? Which is the loudest? Which one should I put on my 09 GT 500? I prefer louder but not cackling! Thanks again Ben Link to comment Share on other sites More sharing options...
cobraeric Posted March 10, 2015 Report Share Posted March 10, 2015 I had a set of the Ford Racing Stingers (49 State legal) on my stock 2008, loved the sound but didn't like the drone around 1800 rpm. Great sound, loud when you get on it. Shoot me a pm with your cell and I will text you a video clip of it at idle. Replaced them with KR's not as loud but no drone. If you are running a taller gear than the stock 3.31's you will not have the drone at crusing speed since your rpms will be higher.

2007tungstenGT500 Posted March 11, 2015 Report Share Posted March 11, 2015 5GT and SGT are identical, just marketed differently (one for 4.6 and other for 5.4). i read somewhere that the the SGT had an extra baffle but i've ran both (one on my mustang GT and the other on my GT500) and they sound the same. they also both drone in low RPMs under load. they are made by Borla for Ford Racing. 5230-S are the same as the KR and are the ones to get. Not sure who manufactures them, but they are NOT Borla. Link to comment Share on other sites More sharing options...
one.wicked.stang Posted April 11, 2015 Report Share Posted April 11, 2015 Ive got the KRs on my 07 with an O/R H and it is loud and has some raspiness and trumpeting, not sure if I like it. Thinking of adding a catted H back on and/or gears to maybe change the RPM range. Ive got to do something because the sound of raspy and trumpeting annoys me..

Rattlesnake Posted April 13, 2015 Report Share Posted April 13, 2015 I like the KR mufflers as well. I went with Corsa tail pipes and their mufflers in the end. And I really like the sound.

rheller Posted April 22, 2015 Report Share Posted April 22, 2015 My mechanic and I installed the KR mufflers on my 2008 GT500 yesterday. First...do shop around online. Prices vary considerably. Second...we had a hell uv a time figuring out how to mount the new KR mufflers using the original hardware. We all but gave up until we discovered that the mounting brackets had to be reversed. That's right. Flip them. End result is a terrific sound. I wish I hadn't waited this long to make the change. Link to comment Share on other sites More sharing options...
