Rins05GT

Hey guys, i'm thinking of upgrading my exhaust on my auto gt. However I want to be sure I get the best sound. One of my friends drive a pretty much stock chevy silverado with the 4.8 I beleive engine. He put a flowmaster super 40 and it sounds like some serious muscle truck. I like the sounds you hear like on a 70's mustang or camaro. I really don't like the racey light hum sound or high pitched vroom sound. I like the gurgly, rough sound. In later model year cars (mid 90's and and above) I've noticed it more in camaro's than mustang's. Any why do you guys suggest I do to achieve that sound?

American Thunder Axle back Flowmasters have just what you are looking for. They were designed specifically for the 05-06 mustang and are very similar to the Flo 40s your friend has.

I 2nd the Flowmasters. IF the Flowmasters themselves are not good enough for you, get headers and an off road H or X pipe too.

Remove the mufflers add slp loudmouths and make your friend jealous.

Flows are definitely the way to go if you want a deep muscle car sound. However, I've noticed that if you take out the cats and go with an off-road x-pipe or pro chamber setup with the Flows....they seem to make a high pitched note for like a second or two at around 2,500 RPMS. Its kind of annoying, but if you keep the stock h-pipe with the cats...the Flowmaster American Thunders sound killer!
I am waiting to get my off-road h-pipe from Brent at brenspeed.com, and hopefully that will alleviate some of the problems those of us with flows and an off-road setup are having.

Flowmasters are a little too rough for my tastes. I think the exhaust tone should be more about quality than quantity. I'll get some audio of my setup (JBA Titanium Ceramic-Coated Shorty Headers and Magnaflow Cat-Back) tonight or tomorrow.

Another vote for the Flowmasters, I don't find them to be just loud. They have a nice rumble to me.

Depends on how much you want to spend but I vote for the SLP LOUDmouths if price is a factor.


Hey Scothew? Isn't the saying,"What would Brian Boitano do?"

Scothew

I think its open to interpretation

I have the American Thunder Kit from Flowmaster and love it.

Here's a link to all the Flowmaster sounds. The Super 40 is the
muffler used in the American Thunder Kit.

Flowmasters add a nice low rumble and they sound very good. I have been very pleased with them.

I made a couple video clips of the Flowmaster American Thunder exhaust a couple of weeks ago. If you want to check them out, go to my website www.2006-Mustang-GT.com, and click on the "My Video Clips" icon on my homepage. There are 2 videos at the bottom of the list that are of the Flowmasters. I hope this helps you out.

I paid about $275 or $285 for these Flowmasters from Summit Racing, which includes shipping costs.

Kenny,

I really enjoyed your video clips. They sound and look great and should help anybody out who is on the fence about purchasing the flowmasters.

SLP Loudmouths have that deep rumbly old muscle car sound. They are deep, throaty, and they "burble". I suggest you watch the videos in the Sticky Thread.
