BLUE 2010 SHELBY GT 500 Posted November 24, 2010 Report Share Posted November 24, 2010 I love my 2010 GT 500 but find the sound of the exhaust to be too quiet. Is their any modifications that can be done to the stock exhaust system or do I need to go after market for a more aggressive sound? i have a 2010 500 ,i change mine a few times, first i put magnaflow cat backs, car got quieter, put back stock and ford racing shorty headers, not much more sound , then put on corsa sport now a little more sound but the big difference is when i put on lethal performance mid pipe now the car sounds like a shelby, only agressive when starting and when you jump on the car , love it Link to comment Share on other sites More sharing options...
SVTSnake Posted November 25, 2010 Report Share Posted November 25, 2010 All you need to do is get rid of stock cats. Use an off-road X or H pipe, preferably use Hi-Flow Cats. Magnaflow or Lethal X-Pipe is the way to go. The stock '10 mufflers are rather free flowing with the changes Ford made to them and sound really good when you ditch the stock cats. Best to decide what you want to do regarding the cats before you start spending money on mufflers, and decide you don't like what you just bought. I've seen way too many guys spend money on 3-4 muffler changes and never be happy with the sound. If you insist on changing mufflers first, I suggest buying used sets until you find the sound you want. Always mufflers for sale in classified section or try market on the www.svtperformance.com site. Good luck in your quest. Link to comment Share on other sites More sharing options...
shel-b001 Posted November 25, 2010 Report Share Posted November 25, 2010 I watched this site as several members changed there mufflers numerous times but found that the kr muffler was the most popular so I put them on what difference in sound with no highway drone .

SicShelby Posted November 25, 2010 Report Share Posted November 25, 2010 Cut out 1 foot of pipe, insert a y-pipe with an electronic cutout... loud, quiet, loud, quiet, with a touch of a switch. Works for me! Link to comment Share on other sites More sharing options...

Crushinator Posted November 25, 2010 Report Share Posted November 25, 2010 Get the Roush O/R muffler delete and will never look back..........I promise !! I agree! I put on the Maganflow muffler deletes and the car now sounds incredible! Plus they save about 30 to 35 lbs from the stock mufflers. Link to comment Share on other sites More sharing options...
GT500 rolls Posted November 25, 2010 Report Share Posted November 25, 2010 I didn't like the stock 2010 sound either, it was too quiet. Researched and decided on a quick, great bang for the buck mod. M5320-S (KR) mufflers. Amazing sound but not too loud if you keep your foot out of it (great for my neighborhood) but lets the full sound come out when you hit it, no drone and just enough pop on decel. Took me 45 minutes to swap out the stock and put in the new ones. No cutting, just unbolt the pipe clamps and muffler hangers and install the same way in reverse order.

inyadreems Posted November 27, 2010 Report Share Posted November 27, 2010 I have the stock exhaust with a custom tune and IMO it sounds awesome! People always ask me what kind of exhaust I have. The tune made the exhaust much louder especially at WOT and a nice gurgle on downshifts. Link to comment Share on other sites More sharing options...
SVTSnake Posted November 27, 2010 Report Share Posted November 27, 2010 I went on the Lethal Perfromance website and saw that they have both a catted and uncatted x-pipe, Are you suggesting the uncatted version? Get the Catted version for street driving. You will get ZERO DRONE with your stock mufflers, but will greatly improve the sound. As you see you will get a different opinion on mufflers from everyone. KR's, Corsas, etc. You don't need those on the '10, just use hi-flow cats. But that is just my opinion also. I have an '09 and am using Magnaflow Hi-flow catted X with stock '10 mufflers. Sounds great, get a lot of compliments. You can find the Lethal pipe used sometimes if you look around. I got my Magnaflow X used for $250 and the '10 mufflers for free!!! Can't beat that... :happy feet: Good luck! Link to comment Share on other sites More sharing options...

I want more sound but don't want the drone of an off-road pipe. I had toff-roads with my '08 Roush and while the sound on exceleration was awesome, the drone while cruising was a killer.

SteelTownStang Posted November 27, 2010 Report Share Posted November 27, 2010 Another vote for Roush Extremes (o/r cat-back)... PERFECT agressive sound w/o the dreadded drone... I also liked the Mac Boomtubes, but they lack the quality of the Roush... Actually, any muffler delete system (SLP, Pypes, etc.) will be a big improvement IMO.

The tune made the exhaust much louder especially at WOT and a nice gurgle on downshifts. Yes but don't you have a 2011 with the H pipe? I think the 2010 is different set up. I had a 08 KR and it sounds very much like my 2011 Gt500 exhaust. I like the look of the 4" pipes out the back. Link to comment Share on other sites More sharing options...
tpenziner Posted March 25, 2011 Report Share Posted March 25, 2011 It's going to come down to personal preference...

It indicates it is the axel back muffler only which is what I am looking for to save some money (not the entire exhaust system). Did you have just the axel back mufflers and if so, where did you get them. Thanks. Link to comment Share on other sites More sharing options...

As of a matter of fact, I just got out underneath my 2011 and put on another Corsa system, that's how much I like the sound! Link to comment Share on other sites More sharing options...
kawwy600 Posted March 27, 2011 Report Share Posted March 27, 2011 i'm looking at lethal performance website and i can only find the catted x-pipe with the headers. not x-pipe alone. anyone have the part/model number? Link to comment Share on other sites More sharing options...
2010KonaBlueGT Posted March 27, 2011 Report Share Posted March 27, 2011 Absolutely No-Drone on the new Roush systems............. And they just had a 10% off discount on their exhaust.... But they DO have free shipping through March 31st so you can save a few bucks if you want one from Roush. Frpom my Roush newsletter: "Get FREE SHIPPING on retail orders of $250 or more made through the ROUSH web store from now through March 31st." There is no drone on the 2010 versions because they put a piece in the midpipe that looks to be a very small resonator to kill the drone. I bought one too, just haven't started the car with it on....YET. Very close though, Phill Link to comment Share on other sites More sharing options...
