Aggressive Muscle Car Sound. Let everyone know your 2011-2014 V6 has arrived with the aggressive sound of this high performance Roush exhaust.

The tips are finished with a new chrome flashing process that is resistant to discoloration due to exhaust heat.

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)

I have these for a 2012 mustang will they fit a 2014 mustang gt?

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!

    Roush axle back 11 v6

    Installed these just a few weeks ago and still to this day don't regret the decision.. Great sound for a sixxer... Installation wasn't hard at all. Maybe 45 mins... I love the compliments I've been getting and the heads that are turning when I ride by!

    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!

    Awesomeness

    Wow, these are loud... And I love them!!! Videos do not do them justice as far as how booming loud they truly are. Nice exhaust note, hearing them makes me smile everyday.

    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!

    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.
