Default Flowmaster American Thunder Axle-Back Exhaust?

Does anyone have the Flowmaster American Thunder Axle-Back Exhaust? It's on sale at American Muscle until tomorrow for $309 with free shipping. I don't want anything too loud or with too much drone. I'm thinking that $309 is not a bad price. Comments/thoughts?

They sound sound good. It's louder than stock but not too much. I don't know how the Flowmaster A/Ts are but the flow 40 series which I believe are the mufflers used to make the Flowmaster A/T axlebacks, did drone in my experience.

The ones that are on sale on AmericanMuscle.com are the American Thunder 17410. From what most ppl say, they are lounder than stock mufflers but not too loud and do not drone. The other set Flowmaster makes is the American Thunder Classics 817460. That set uses the classic original 40 series mufflers and are rectangular shaped with 4 inch tips. I just put the A/T classics on mine. They do drone pretty loudly from about 1600-2000 RPM and have a much more aggressive sound than stock mufflers.

I have them. I like the sound and it's not too loud unless you lay into it. I also like them because they do not have that raspy sound that some of the other mufflers have.

Idk, many people on here in the past have got them and quickly switched out. The vids are all out there, it's up to you if you like the note. Also, the vids and in person are quite different but you can get a little idea. Stay far away from stingers or mac if drone is a problem.

I loved them on the 05gt. On start up there was a nice rumble and during even somewhat hard acceleration the same. A bit of a drone occurred around 2000 rpm's but I did/do not do much highway driving so it was not an issue for me. I still miss that sound compared to my Magnaflows on the 09. Oh well. Good luck with your choice. I hope this satisfies the mod that stated I posted useless replies

I have them....considerable drone in a very narrow range between 1800-2200 RPM for me. Not a problem though.....and has settled down over time. You can get them to drone if you give too much gas in too low a RPM. 4th gear at 45 MPH at 2000RPM's or so is not good, so I just stay in 3rd and raise the RPM's a little. Otherwise sound great and lots of complements. Sounds old school nasty just cruising along and really gets loud when you get into it....never raspy. Love them.

I have them and the drone is as advertised 1800-2100 rpm in 4th of 5th. I personally dont like the drone and am currently looking at other options.

Damn, I had my mind set on the 817460 model but I do alot of interstate driving and that puts me right around 2,000 rpm's for the majority of my driving. I don't want to shell out almost $400 to be disgusted with the droning.

I put the AM thunder axelbacks on my 05 GT almost 5 years ago and love them. Perfect fitment the first time, and no issues of any kind. I don't notice a "drone" but they are a bit louder than stock but not irritating like the SLP loudmouths. Those mufflers sound fantastic with long tubes and hi flo cats.

I got mine on eBay for less than any of the the vendors but it was so long ago I don't remember the actual price, but $309 doesn't sound too bad.

Good luck to you what ever you decide...

for the most part, when you deal with mufflers...to get a nice aggressive sound you'll most likely deal with drone around 2,000 rpm. It's all about what you want more, better/louder sound will equal more drone.

I've had them on for about 4 years. Drone has never been an issue for me.

I have them with an H PIPE and Detroit Rocker cams and the would trumpet bad. The drone was not bad at all and i actually liked it but the trumpeting was just too much. I think its more significant with cars that are autos. I put on some HI FLO CATS and it has resolved my issue and now my exhaust is awesome

I got my GT in 2006 and put the 60 series on them. I loved them. After 4 years, the insides went bad and started to rattle really bad. I decided to purchase the newly released 40 series... bad idea. Drone is HORRIBLE and ever time i accelerate, there is a loud popping sound from 2k-2,5k RPM. Now, keep in mind, i have pypes long tubes and off road h. I wish i could go back to the 60 series. Just sounded soooooo much better in my opinion. The 40 series sound nice on earlier cars but you really need more pipe after the exit of the muffler like on the 04 of before mustangs.

Thanks for the replies. I did a little more research and decided to hold off and get a set of the Corsa's. Unfortunately they are twice the price but will be worth it.

You can hear the new Roush system here:

I think they sound nice, and they advertise no drone.
