Check out this video, this sure sounds louder than stock to me. I think this is a GT-H because of the hood and I don't see any shifting.

The Hertz that I rented did sound a bit louder than my GT with the GTAs - if I am remembering correctly.

The Shelby also has the X-pipe (mine doesn't), but I've read that it really doesn't add to the volume. Maybe it does.

Another factor might be the Shelby's CAI and 91 tune - my car has neither.

My GTAs come alive at about 3500 rpm. They sound pretty much stock (at least inside the car) at lower RPM. But at WOT, they sing.

One thing I've realized about this generation Mustang is that because the mufflers are so far back, they seem to sound quite a bit louder from the outside than from the driver's seat.

 

Sounds like mine!

 

Maybe you just proved my above theory - I need to add the X-Pipe, CAI and tune!

 

They are louder than stock,what are you talking about

 

sounds badass. i still love my flowmaster axlebacks but me thinks me needs an x-pipe this summer

 

Yup and you can see the Shelby signature on the dash too.

 

My GTAs are definitely louder. The Hertz I rented was definitely louder than my stock GT. Now that I have them I can tell they are starting to mellow somewhat and get a little louder. They "burble" when letting off the gas a little. Great sound with no drone in the vert.

 

Of course they are louder, and the X-pipe makes them louder still

 

Is that a "for sure"? There has been some debate about that.

If so, is it "a lot" louder, or a little?

 

Yes, it is a for sure. It is not tremendously louder, but it is louder, it would be closer to little than a lot though. I was the first to get and install the GTA's, and I am somewhat amused how some (that don't have them, and are only speculating) say that the FRPP X-pipe makes a higher pitch, when in reality it is the opposite. That may be true with some X-pipes, but not the FRPP one that the Shelbys use and I have installed. It smoothed the exhaust pulses out and gave it a lower, louder sound.

 

Hmmm...I may reconsider one! Thanks.

 

Thats exactly what I noticed.I had installed the FRPP X-pipe before removing the Stingers and it sounded a lot smoother( it still had the trombome drone @ 2000rpm).Then I traded for the GTA's and they sound off when thrashing but quiet down on cruize @ 2400rpm.

 

I just ran across this and it looks like Supreme Performance which makes the GTAs also makes the CherryBomb mufflers too.

Check this out!

I dont doubt they are a little louder. But to be honest, the car in the video essentially sounds like my stick GT.

Don;t forget the stickshift GT's have different mufflers than the autos I believe.

 

I have a 5spd manual and that sounds deeper/louder than mine for sure. I wonder about the dreaded drone though.

All the drone talk has me keeping my distance from FRPP/Borla and I thought I wnated GTAs but I'm concerned it won't be enough of a difference for me.

I need to hear some of these setups in person in order to make a decision.

 

your the first person i ever herd say that

 

I don't remember what stock sounded like but I will say that video made me feel motion sick and now I feel like throwing up

 

Apperance wise, those 'Cherry Bombs are identical to the IMCO Extremes I tried first. Great sound, bit loud, but the drone was terrible between 1800-2000 RPM. I pulled them off after 60m.
Haven't looked back since I installed the GTA's.
Just my 2 cents worth.

 

GTA's sound too quiet imo.
You're paying how much for a better sound at WOT?

I don't know...might as well keep the stock mufflers imo.
