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.

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)

Gurru1321

  • unfortunately no - these are designed specifically for the V6 not the GT. if u are lookig for the GT set you need to get #421127 set since i believe the pipes are a different size BUT they are the same price on here!

which is louder borla S-TYPE roush´╝č will s-type pops and gurgles when shift or decelerate´╝č

aa

  • As a current owner of the Roush exhaust, I have to say that the Roush axle-backs are much louder. The Roush axle-backs have a much raspier exhaust note, while the Borla S-Types have a more deeper sound. Both exhaust systems provide pops and gurgles when you shift, decelerate, and downshift.

Im am stuck between the Roush Axle-Backs and the Pypes Pype Bomb Axle-Backs. Im am going to be purchasing a tuner and a cool air intake soon and would love for some input of those as well. Thank you.

Keegan

  • If your budget allows, you can't go wrong with Roush kit. They are very high quality and fitment is always spot on. The CAI and tune will give you more HP and Torque. The Axle-backs will complement the tune and give your Mustang the sound it should have had when it left the factory. Good Luck!

Does this exhaust require a tune? Would it be more beneficial to update your tune specifically with these axle backs? Thanks

  • Axle-back exhausts do not require a tune. You can simply bolt them on and enjoy!

    Deep and Very Loud

    First of all this exhaust is crazy loud. In my opinion this is the deepest and loudest exhaust for a v6. If you have a manual your car while sound mean, a cold start is nice and loud and even a warm start is still decently loud. One thing that some may not like is that from shifting from 1 to 2 to 3 if you reach around 3000 rpms it will make a loud pop like a gunshot which i think is awesome but some may disagree. If you don't know what exhaust to get, get this one. My dad has a 09 Bullett and his sound is amazing. and this exhaust is close to the same. Same level of loudness but a little more high pitched. install was fairly easy the hardest thing was getting the stock exhaust off but after that it was a breeze.

    Roush Axle back on v6 2014 mustang

    It sounds amazing. If you've heard sound clips it's nothing compared to how it sounds in person. It sounds nice and deep when you turn it on and even better when you step on the gas.

    Make the right choice!

    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!

    ONLY REVIEW YOU NEED TO READ

    So i ordered these sunday and they arrived wednesday. So the only hard part was removing the stock exhaust. Clamps came off and to get the bolts out, you gotta do some pushing and force to get them out. Use oil or lube to remove it faster. Theses exhaust slipped right on with no installation problems. They are very loud but not to the point where they are annoying. Took 40-1hour to remove and install. Videos cant really give you a precise sound but trust me, they are nice. Nice rumble around 2000rpm and Roars around 4000rpm. Really recommend because i heard pypebomb exhaust didnt fit too well so i spent the extra money and got these. Really no regrets.

    Sweet Sound!

    These look and sound great! Gives my car the rumble I was looking for. They're not too loud, but give a perfect sound. Installation was easy and took 30 minutes. Putting the car on ramps definitely makes installation easier. It helps to have a 2nd person to hold the old mufflers while removing them. Would definitely recommend the Roush Axleback!!

    WOW

    I had to admit, I couldn't wait to find that right exhausts for my '13 V6. I had gone through so many different sound clips and I finally decided to go with the Roush since it had so many great reviews. First off, if you're anything like me (searching endlessly for sound clips online) there is no video available that truly captures the exhaust note of this exhaust. In person it has truly lived up to my standards... in fact it has surpassed them. These are LOUD. I like that I can punch it to 3k+ RPM and hear a loud raspy exhaust coming from my car. When idling it just sounds great. Between 1k-2.3k RPM its just a little noticeable and that is just how i like them. The install is so easy a cave man can do it. It took about 30-45 minutes to install them. In my opinion getting the OEM parts off where the hardest part. Just use a jack and some stands and it should be a pretty smooth install. I didn't even really have to use the instructions that came with it because it was just that easy, I highly recommend this product to anyone. American Muscle has done a fine job sending these to me as I had received it just 3 days after ordering them!

    Looks great, sounds decent, fit bad

    Installation took about 30 minutes and was very simple. The tips look fantastic but I am not very happy with the fit. The exhaust on the driver's side of the car is sticking out about 1/2"-1" more than the passenger side. No matter what I do I can't get it to adjust and be even with the passenger side. They are very loud, but the tone is decent. Drone isn't too bad with the windows up, AC cranked, and radio on. The tone actually changed quite a bit and got a lot more popping when I put the CAI in. Overall, I like the exhaust, but not happy with how it fit. It is pretty obvious that one side is sitting out more than the other. I found a guy on youtube who reduced the raspiness of the exhaust by adding some Thrush glasspacks inline as resonators. It made the exhaust sound 100 times better and I think I will be doing that next.

    I had this installed at a local shop. It took them less than an hour to put it on and they only charged me $100 (well worth the money). This was my first real mod to my 2013 and it's the best investment I've ever made! Sounds AMAZING!

    2013 V6 Roush Axle Back

    I did alot of research online reading reviews and listening to sound clips. Like most reviews say, the sound clips really do this exhaust no justice. Yes its loud. Not annoying though. I would Definetly reccomend this product if you don't want to spend the extra $200-300 for the borla. It's got a great note and I love the gurgle and pop in between shifts. There is very little drone inside the cabin and it's only in 6th gear. Still able to talk on my Bluetooth no problem. Shipping was fast and easy. I had it installed at Miidas for $100. The guys at the shop loved it and said it sounded very similar to a 2012 Boss that was in there. I didn't notice a change in gas milage but this exhaust is much lighter than the stock. The chrome tips are just beautiful. If your considering buying Roush, just go for it. You will be happy

    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.

    V6 Roush exhaust

    This exhaust is really a nice sounding exhaust! It makes my v6 sound like a v8! When you're on the highway, or cruising around 25-30 mph, the exhaust has a really nice rumble that isnt too loud, which is a good thing for me. You can actually hear the person next to you talking. But whenever you punch it, it definately SCREAMS! It just SCREAMS power! This exhaust is definitely worth every penny and the time you spend! The only bad thing about this exhaust, is that if you live in a small town like me, the cops will be all over you if you punch it. Because the exhaust screams soo loud that you can hear it across a 2000 population town. But it just makes it fun. ;)

    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).
