Product Description

Flowmaster 817460 - Flowmaster American Thunder Classic System Axle-Back Exhaust Mustang 2005-10 GT V8.

Since the early 1980’s when Ford released the now famous 5.0L HO engine, Flowmaster- Equipped Mustangs have become the signature sound of the modern muscle car era. Flowmaster’s new axle-back system for the latest generation of 05-08 Mustang’s delivers improved performance, looks and a sound reminiscent of those early 5.0L cars. Featuring Classic square cased 40 Series® mufflers, the kit follows the factory exhaust routing, utilizes the factory hanger mounting points and includes all necessary mounting hardware for an easy and perfect fitment. Designed for the serious enthusiast who really wants to hear their pony breathe, these mufflers produce a deep and aggressive exterior tone on the throttle, along with a considerable amount of interior sound. For those looking for performance, but with a tamer sound, Flowmaster also offers a quieter alternative (part# 17410)


  • Signature Flowmaster Sound
  • Patented Delta Flow® muffler technology
  • Durable 409S® stainless steel construction
  • Easy bolt- on installation – no system modification required
  • Ten year limited warranty
  • Made in USA
  • Fits Shelby

This is a good set of aftermarket mufflers. They sound good and are not too loud. There is a bit of drone from about 1700-2000 Rpm's. It does not bother me, I knew these Flowmasters would do that. I think they are very good and I am satisfied. They do give a very deep tone. I have gotten several compliments about the sound on take-off and idle. If I had it to do over, I would still buy them. Thanks LMPerformance for the best price I could find. You have a customer in me for years to come and I will recomend you to all of my fellow car enthuiasts.

I actually bought these to replace the 17410's that I had installed a couple of years back. Overall I think they are made pretty well. The sound is a little deeper than the 17410's which is nice. They are not too loud but you can tell they are there. Yes there is some drone but same as the reviewer above me I expected that. I have always liked the Flowmaster sound and have never had any problems with their products. It's a good product for a great price. LMP shipped them out immediately. All that being said I have only had them on for a couple of days now but I am happy.

5 Stars Great sound!, Date: 6/28/2011

By: Mike

First of all, shipping was VERY fast - thanks! Install was pretty straightforward. Took a little less than 2 hours. The clamps supplied are top-notch. The sound of this exhaust is great! Very, very deep sound, especially under 2000 RPM. I find it has the most interior resonance from 1500-1700 RPM, but I rarely cruise in that range - and I love the sound anyway. The often-talked-about drone at a 2000 RPM cruise is almost non-existant on my car (3.73 gears, manual trans). At highway cruising speeds, they are not loud, but you can tell they are there if your radio is off. Under heavy throttle, they are fairly loud, but not obnoxious. I highly recommend this system to people who like hearing their exhaust at part-throttle acceleration as well as WOT. If you like it silent inside with the windows up, you might want to look into quieter alternatives.

I have the 1lt (base vette non npp exhaust). Installed this part yesterday evening with a friend. There is a video on youtube that was for another manufacturers larger system that helped with removal of the bumper and factory exhaust. On the way to work got a check engine light. Flowmaster is aware of the issue and is going to have me speak with R&D tomorrow!

I watched countless YouTube vids of axle backs for my car. Let me say they're essentially useless! Based on the videos I had my heart set on a ford racing or borla touring exhaust. They seemed to have the deep sound I was looking for without being obnoxiously loud. I was avoiding the flowmaster setup based on a few videos that made it sound too high-end and not rumbly. I was set to spend 700 on the borlas but stumbled on a vid of the flowmasters that sounded good. So I decided to risk it to save some dough. I'm not disappointed. I put them on in under an hour. The fit is stellar. So easy to line up in the valence, looks great! If you're looking for a crazy loud system this is NOT for you. It's not much louder than stock, but has a much beefier sound. There's no drone in the cabin unless you really are looking for it. At cruising speeds with the radio on you can't hear the exhaust. Dip your toes into the gas tank and it roars pretty good, but again nothing obnoxious. I think it's perfect for a daily driver.

Had the American thunder cat back installed by dealer. Sounds ok from the outside. Has a terrible load low pitch drone the feels like it vibrating the inside of the car. the sound is most noticable as the rpm reach the point where the car up shifts. The noise is very annoying. I will be making an appointment to replace the original.

By: Mikenholland

I did alot of research on doing such an upgrade, I found this system to be the cheapest in cost compared to other sites, and on Ebay. There is even a video on YOUTUBE that shows the step by step process to doing the removal of the old system and install of the new. Just do a search for Dodge Charger Flow master and I'm sure you will find it. I watched it I don't know how many times looking to see if they were leaving anything out so once I got the system delivered my only problem was cutting the pipe. I had no way of lifting it on a hoist or jacking it up more than 2 feet but in all honesty, this system can be installed in about 10 minuts if have have all the tools readly availabe and you dont have to stop to get out from under the car. I bought ramps at autozone drove up the front end then jacked up the rear end and used jack stands to support everything I was small enough to fit under and make the cut and everything went as smooth as the video I was really excited to how easy everything went once the cut was made and everything fell right out. Do soak all the rubber mounts and loosen them up prior to remval, you won't have to fight as much, keep the very rear one in place. The exhaust does have a rumble at idle and did turn heads when I got on it, however this is not a loud system and that works perfect for me. I really just wanted dual exhaust with just a little bit of noise. I am 100% happy. Also the exhaust clamps provided are the same oem style ones and do not look as cheap as the ones in the video.

Looked around and found the Force II exhaust to be the best one for a driver not looking for the sound as much as better p/u and gas mileage. LM Performance by far had the best price. Came complete and all parts are wraped so no scratches, dings, needed nothing extra all parts included. Took it to Dennis my mechanic and in 1 hour we had it on and welded it also. Very nice looks and sound gets better in time. Very mild. I had gone to Utube to here it prior to buying. Very happy!!! JA (Cumming Ga.)

Great system. Strapped it to the chassis dyno and it does everything flowmaster said. 5 more peak horse at the wheels and great bottom end gain. With the improved low end power I'm pulling 2.5 more mpg, IMPRESSIVE! *PLEASE NOTE* I installed this on a 2011 and the instructions say to cut 9 inches forward of the hanger. This is incorrect, I cut 6.5 inches forward.

The quality of construction on this kit is excellent, actually much nicer than some more expensive competitors. If you are looking for a loud exhaust look elsewhere, this is a very mild sounding kit free from drone at any speed. The power increase is noticeable, definately a worthwhile kit for performance and daily driver friendly tone. Good job flowmaster!!!
