Great product

Installed this system quickly and they are great sounding to me. However, if you or your neighbors have sensitive ears, they may be a touch too loud but I love 'em.

Oh it's definitely loud, but it's a great loud. I heard that the Roush was raspy, I wouldn't call it raspy so much as unique. You aren't gonna sound ricey but you aren't gonna sound like a V8 either, it ...

square tips will the square tip version of these fit within the normal rear valence without modification? im torn between these and magnaflow competitions

blake2012

  • My friend recently purchased the Square tips for his 2013. They do fit within the stock axle back cut outs. But it does look ugly in my opinion. If you do buy the square tips, I would suggest getting the valence.

Why does the picture here not match the Roush Website for the same part number, 421145? The hangers and finish pictured look different than the Roush website.

SCRPION

  • I'm not sure why Roush has a different picture (I just checked it out as well), But what I can tell you, Is the one you're purchasing looks exactly like the one in the pictures of the AmericanMuscle site. (I purchased these for my Mustang)

    Oh it's definitely loud, but it's a great loud. I heard that the Roush was raspy, I wouldn't call it raspy so much as unique. You aren't gonna sound ricey but you aren't gonna sound like a V8 either, it strikes a perfect balance between the two and sounds incredible. It seems to changes tones throughout the rpms and adds an interesting mix of personality for your Stang. You won't go wrong with the Roush, and it's easy to install!

    2011 v6 ROush axle back

    To start.... wow. The exhaust system was rather simple to put on. 1 hour from removal of old mufflers and install of new ones. They have a great finish.. The worst part was removing the old stock ones. This exhaust has such an amazing tone in prson. NO audio on the internet truly displays the sound quality.... It is loud... but also throaty... and down right nasty at full throttle.... I LOVE IT... It is all smiles from ear to ear. If you are thinking about it... stop... JUST get it.

    Sound Amazing

    Sound is amazing. LOUD and DEEP. When cruising there is little noise in the cabin. but if u try to accelerate between 1500-2000 RPM in higher gear it gets drone inside.2k+ RPM sound is amazing. if u change gear between 3000 to 4000 then u get extremely LOUD POPPING which is the BEST part about this exhaust. i really like them and definitely recommend them.

    Perfect Sound

    Bought this for my 2012 V6 mustang. Prior to the exhaust I purchased the C&L cold air intake. It sounded ok with the stock exhaust but still wasn't the sound I wanted. I looked around and decided to go with the roush exhaust. Glad I did. The sound is amazing. I had them installed at a local shop. As soon as the car started I knew I made the right choice. I put my car next to my dad's 03 Mach 1 (flowmaster 40 series catback system)to compare the sound and the roush kills it. Would highly recommend them to anyone looking for a mean sounding exhaust. (Not for the faint of heart).

    Highly Disappointed with These Axle Backs

    I did vast research when looking for the right exhaust for my 2013 V6... I decided to go with Roush, as YouTube videos portrayed them with the best sound (so I thought). Plus, it's Roush, so I thought I couldn't go wrong. Install was simple, and took less than an hour. Hardest part was getting the stock mufflers off. At start up and idle, the thing sounds like a beast. It has a deep rumble, and sounds great. Anything higher than 2500RPMs, and I am highly disappointed. The first thing my dad said when I pulled up, was "Sounds like my Sentra (Spec-V, in which he has riced out)..." Then I went to my boyfriend's, and the first thing he said was "Sounds like a 4-banger with a coffee can". They are both EXACTLY right! It has the most terrible, high pitched, ricey tone. Trust me, I know it's a V6, but there is absolutely no way that 305hp should sound like this. Long story short, I'll be taking these off as soon as I can. The high pitched, obnoxious sound is too much. I'm all for LOUD, but not the gross tone these axle backs put out.

    Poor quality

    I bought these axel-backs a few months ago, and I wrote a review titled "Pleasently Suprisded". However, now a few months later when I was inspecting the mufflers, I noticed that the left muffer has split along the soddering. This spilt takes up about half of side of the muffler and, has been leaking the black exaust grit on the finnish of it. I think it was due to heat, and poor construction. I know it is cheaper construction because they are MADE IN CHINA. Its more cost effective for Roush, but not true quality anymore. They also are rusting in a localized area of the other muffler and has ruined the chrome finish, and eaten away at it. Im going to try to get my money back because im not dealing with it again, and im going to get the Borla ATAKs. They are made in America, are more expensive due to better construction, and have a million mile warrenty. If you are considering the Rosuh axel-backs, I highly advise not to, and might as well spend the extra couple hundred to not deal with the big headache that I have to deal with now to get my money back.

    Great For The Price

    Extremely loud at first, but after a few miles the volume drops down. Nice tone in lower RPM range, a wailing sound like a plane taking off when hitting 3k+.

    Sounds great after break-in period

    I had my local guys install the Roush axle-backs about two weeks ago. I was amazed at how loud they were when I first started it up. Actually had a police officer friend give me a ride to the shop, and he had to ask, "Do you just wake up every day and think of what you can do to make your car more illegal?"... The exhaust became much quieter after 300-400 miles. I have done about 1k on it now, and the tone has settled down into something very pleasant. From idle to about 2k RPMs, it has a deep V8 sound, especially under load at lower speeds where road noise doesn't overwhelm it. My primary issue with this setup is the note from 2k-3k RPMS. There is a certain spot around 2.7k-2.9k where the exhaust note changes dramatically and becomes very noticeably raspy. The note changes again around 3k-3.1k back to a more aggressive high-end v6 sound, which sound great at WOT. Keep in mind, this exhaust is loud, and there is a possibility of breaking sound ordinance laws if you run WOT within city limits. There are a lot of popping and gurgling noise during deceleration and midshifts which I love. It makes the car sound really mean and I've had a lot of people look when they hear it. I plan on asking my muffler guys what we can do to fix the awful raspiness at 2.7k-2.9k, but other than that the exhaust is awesome. The tips look much better than stock, and fit perfectly with the stock rear end.
