Are the exhaust hangers for 2010 GT any different over 2005-09 GT models

[06 T-RED S/C GT]

I'm interested in purchasing Borla multicore axle back #11784 for my 06 GT.. However Borla lists them only for the 2010 GT500.. Therefore by any chance were any changes made between 2009-2010 as far as the location and dimensions of the exhaust hangers or are they exactly the same ? I was considering ATAK's, "S" type and Roush extreme axle backs, but for the type of sound quality I'm looking for, I'm now convinced the Borla 11784 multicores are my preference of choice.. My biggest concern though is will these fit on a 2006 GT without any major adjustment changes involved.. In the meantime, any help would really be appreciated..

I think the issue isn't hangers but where the actual tips exit the bumper cover being in different locations.

Very good point.. So would the location of the bumper covers also cause enough of a clearance issues for the tips

The research I have done suggests that it can be done, but with some work. I'm not sure it would be worth the headache to be honest. Is there that big of a difference that they are a must have over other mufflers that would fit directly?

After the research I've done between Roush extreme axle back, Borla ATAK and Borla "S" type.. I found the Borla 11784 Multicore for the 2010 GT500 is exactly the sound I've been searching for.. I also spoke with Ryan from Borla who also highly recommends them despite the fact that he knows my car is a 2006 GT but in his opinion feels they would sound the best over both the "S" type and ATAK being that my 2006 GT is supercharged..

The sound a muffler makes for a gt500 is going to be different than it makes for a GT. It's a completely different engine.

So FWIW I have a Ford Racing "touring" (Borla) axle back on my car that was listed as being for a 2010 GT (I bought it used).

The hangers are mostly the same, however I found after installation it seemed to hang lower than other 05-09 axle backs I'd had on the car (I guess to clear the 2010 bumper), and there was the aforementioned tip length issue (they stuck out about 2" past the bumper). Other than that, no issues.

The tips on it were screwed up anyway so I cut them off and welded 2.5 ID adapters onto the pipes so I could run regular ~8" long tips that I had used on other axle backs.

I've been told it's the inlet pipes that are shaped a little different

I totally agree Brandon and pointed out to Ryan from Borla that the GT500 has the supercharged 5.4 (331) 4v compared to my 06 GT 4.6 (281) 3v..

However Ryan claims the Borla ATAK and Borla "S" type are designed specifically for Naturally Aspirated 2005-09 3v engines and will not sound very well on a supercharged application, due to the increased airflow produced by the S/C and would thus change the sound of the muffler.. Therefore he also claims I should install an axle back muffler that's designed exclusively for supercharged applications in order to achieve the sound I'm searching for despite the differences between the 4.6 3v and 5.4 GT500 4v..

What I don't quite understand however, is according to American Muscle's description, the Borla "S" type is listed for both 2005-09 Mustang GT and 2007-09 Shelby GT500 along with the Ford Performance Parts FR500S, Pypes Pype Bomb and Roush Extreme axle back high flow resonator in which Roush claims are designed to fit both 2005-10 Mustang GT and 2007-10 Shelby GT500..

Needless to say, I'm at a complete loss and pretty much confused as hell at this point right now, as you would think a technical specialist who has 20+ years experience under his belt with Borla would provide precise and accurate info lol.

So it would appear that the 2010 rear valance tip cutouts are lower than the 2005-09 valance along with the 2" difference in tip length as well..

From what you've posted and described, it appears as though we're talking more than just a few minor adjustment changes in order for the 2010 GT500 axle back to be retro-fitted on an older 2006 GT

You're probably right about that, as I wouldn't doubt it especially when it comes to Ford lol.

 

[Brandon08GT]

I have heard numerous borla systems on supercharged 3 valves and they sound amazing. What would increased airflow have to do with a straight through designed muffler? I could possibly see that with a chambered muffler (even then that's a stretch) but not any of Borlas. If I lived closer to you, I would let you put on my axlebacks just to prove a point lol. I could very well be wrong, but that's the first I've ever heard such and thing and sounds to me a bit like a sales pitch.

If by shaped different you mean bent differently...I suppose that's possible, I didn't notice them being that different. The inlet itself is identical, the 11-14 have the different ball socket attachment.

If you don't mind the tips sticking out then no, it literally bolts right on. I ran mine last year with the longer tips on it, I didn't think it was THAT bad, but the bottom of both tips were cracked where they'd hit the pavement previously (I bought them used) and the chrome was pitting pretty bad so I had plans to replace them anyway.

The height difference isn't that big of a deal, I mean I do wish they tucked up into the cutouts a little better but the amount of work to make that happen doesn't really seem worth it.

Brandon, trust me.. If I lived closer to you, I'd be more than satisfied just to hear your axle backs on your car lol. Anyway I most definitely agree with you as it doesn't make any logical sense that certain performance mufflers are designed just for supercharged applications while others are designed for just naturally aspirated applications.. it's like you said, how would increased airflow from a supercharger have anything to do with changing the sound of straight thru designed muffler ? I just don't get that nor able to comprehend that at all... Rocky

I really don't think I'd mind the tips sticking past the valance very much.. As for the height difference, I suppose it would all depend on how significant the difference would be

I'll see if I can snap a pic later on.

Brandon, just out of curiosity what brand are your axle backs ? I forgot to ask you about that earlier.. Thanks once again, Rocky

That would be awesome, as I'd really like to see how well your axle backs look I also placed another phone call with Borla and was actually able to speak with one of their engineers at their Tennessee location in which I'm really glad that I did, as Jeff was extremely very helpful and knowledgeable, as he took nearly an hour to explain how Borla designs and engineers their exhaust systems that are specifically tuned for each individual application..

At any rate, Jeff did confirm if I were to purchase the Borla axle back for the 2010 GT500, that it would not be a direct fit due to the muffler hangers being placed at different angles and also from the inlet pipes not having the same bends as the axle back sections designed for the 2005-2009 exhaust components.. Therefore he strongly recommended against purchasing the 2010 GT500 axle back as the previous Borla rep suggested and recommends going with the Borla multicore cat back exhaust for 2007-2009 GT500 instead in which he says should fit my 2006 GT without any major fitment issues involved.. Anyway I've went ahead and included both the part #140210 and link below...

I have the Ford Racing FR500S. It's the same design as the Borla S type. I don't think I have any videos with a more stock setup. I put O/R x pipe on around the same time and now I have longtubes so it would be even more different. I noticed with the changes I made, the axlebacks made the least amount of difference. Biggest difference was longtubes honestly. I wish I would've done that sooner.

 

[ghunt81]

So, this is the aforementioned axle back on my car. The tip alignment is off because something is going on with my H pipe, they're shifted toward the passenger side, and I have yet to fix it (they were aligned better when I put them on, they've moved since I've been driving the car).

So they don't hang down super low, but obviously they don't tuck into the cutouts like they should either. This is the best I've been able to get them height-wise with bending the hangers.

Ignore the vertical black bar on the pic, I took it with snapchat and somehow that got on there when I saved the screenshot.

I've also considered the FR500S as well and IIRC there's been a lot of positive feedback on these forums about having no drone to them at all, but yet still provide a deep/aggressive and throaty tone to them.. However the only cons I have, is they're not offered in T-304 grade SS and don't offer any type of warranty unlike the Borla's that include their one million mile warranty.. But my main concern is sound quality and the least amount of inside drone as possible..

First, I'd like to say thanks for taking the time in posting pics of your axle backs.. From your images, it really doesn't seem that your tips hang that low to me IMO.. I do however notice how your passenger side alignment is off due to your H-pipe shifting.. But I'm sure that once you get the H-pipe fixed, you'll have both sides properly centered with no problem.. Although I am a bit curious as to why you went with an FRPP axle back designed for a 2010 GT rather than a 2005-2009 axle back designed specifically for your car

Because I got it for $150.

Also, I had formerly been running a chambered axle back and while I loved the sound, the drone was killing me. Saw these and figured I'd give them a chance, turned out they were really great and had much less drone.

Being that you got them for $150.00, I would've done the very same as well and like yourself, I also can't stand annoying cabin drone
