Force II Flowmasters/Borla/...or leave it alone?
 

I apologize if this question has been addressed before, however, I don't have time to scroll through all the posts.

I have a stock 2000 GT Mustang. I want to increase the gurgle/rumble noise, however, I don't want the loud piercing flowmaster 2 chamber affect. I want the stock sound to change to a deeper/meaner sound, with a definite audible difference.

Has anyone done this to their 99/2000 GT? Is there a distinct difference between the low growl stock sound and the force 2 and or Borla? Any information would be appreciated.

If you keep your stock H-pipe on and install an aftermarket muffler, the sounds will not be too loud. Flowmaster has a throaty, aggressive tone to it. Flows are loud at idle and super loud at Wide Open Throttle. While the Borla's offer a deep tone, that is quiet at idle, and really makes noise at WOT. If you don't want your exhause to be too loud, then I suggest Borla's (if you have the $$$) or MAC mufflers.

Thanks for the info.....

However, is there a significant difference between the Borla and stock? Do you think it is worth the money if I can afford it?

Check the post for "Mufflers" that Dino posted not to far down.. Since the two years are almost identical, I'm sure that post will apply.

Dynomax are still better... Good luck!

I think I am leaning toward the Borla catback....I like the sound. I know it is a little more expensive, however, too many people have the Flowmaster setup.
Now all I need is my X-pipe and I'm ready to go!

Borla mufflers are the most overhyped,overpriced muffler that exists.Spend/save your money on something that will make a difference,ie:manifold,head porting,new pistons,etc.Forget the preoccupation with mufflers,on nearly stock
cars they yield 5-10 hp and they rob low end
torque anyway.

Borlas sound awesome on a mod-motor car, but they're REALLY expensive. I want them, but I'm probably going to put the same mufflers on my '96 Cobra that I had on my '88 5.0 LX....Dynomax Super Turbos. I haven't heard them on a Cobra yet, but they sounded terrific on my '88. And at less than $40 a piece, they're really cheap. Anyone bolted Super Turbos on their mod-motor Cobra with a stock H-pipe? How does it sound?

Go with Flowmasters Cat Back, Bassani Cat X-pipe(because the computer senses the Cat removle, and will screw the car up)and then Motorsports high flow shorties.
