2011+ STi/WRX Sedan Quad Tip AxleBack Muffler Replacement w/ 5" Mufflers

Calculated at checkout

Product Description

Get the original axleback for your subaru with the all new muffler addition! For those who want the sound and tone but like the volume lower and more refined than our original axleback we have developed a muffled axleback using a proprietary muffler that we designed and tuned specifically for this application. The mufflers are all built by our fabrication team in-house using our standard quality control process and only the best materials. Building these in-house allows us to control every aspect of the quality from materials to the way they are welded. We use a proprietary material inside the mufflers that withstands heat up to 2500 degrees fahrenheit so you don't have to worry about them blowing out or changing tone over time.

We saw a 20db reduction at idle and a 10db reduction during free revving from our standard muffler delete with our 4" muffler and these are even quieter with the 5" mufflers.

The picture shows the staggered single wall tips.

Designed for the 2011 Subaru WRX and STi Sedans, the Nameless Performance AxleBack Exhaust is a direct factory fit to the OEM midpipe at the Y.  These axleback pipes replace the two factory 13.5lb mufflers with a pair of mandrel bent, TIG welded, T304 stainless steel pipes and configurable tailpipe tip styles.

Factory fit laser cut flanges and 2″ dual piping has equivalent cross sectional area of a 2.85″ straight pipe, providing excellent breathing characteristics for high end horsepower as well as retaining low end torque.

Fits 2011+ STi and WRX Sedans.


Tailpipe Tip Options:

Quad Staggered Double Wall Round Tips:  We think these are the best option, these are T304 stainless, double wall polished tips that fit perfectly into the cutout in the rear valence of the vehicle.  10 Degree Angle Cut with staggered arrangement (inboard tips stick out 1/2″ further than outboard tips). 3″ diameter per tip.

Quad Straight Double Wall Round Tips: Same as the staggered, but even offset on the tips (no stagger). 3″ diameter per tip.

Quad Single Wall Slash Cut: Single Wall Quad Tips w/ 20 degree angle cut.  3.5″ diameter per tip. 

Quad Single Wall Slash Cut Staggered: These are the same as the 3.5" single wall tips only they are staggered by ½” to match the valence better. We stagger these in-house so we have to add an extra $30.

  1. Perfect for a civilized exhaust

    Posted by Beau on 27th Feb 2014

    What a great setup. I wanted an exhaust that would give me that deep boxer rumble and awesome sound under acceleration, but not be obnoxious or drone. This setup is all of that and more. It's just loud enough to turn heads and sound great, but is very civilized. I think it's actually quieter than stock at idle. I commute on the freeway 60 miles every day, and this exhaust does not drone at any speed. You can easily carry on a conversation inside as well, it's only loud when you want it to be.

    Fit and finish are second to none, I had mine installed within 30 minutes of delivery.

  2. Muffler shop was blown away

    Posted by John on 6th Feb 2014

    My 5 inch muffler set up with double wall staggered showed up today , and since it was 24 degrees out and I didn't want to lay on cold cement , I opted for muffler shop install ,muffler shop was blown away by quality of welds and engineering , bonus was the actually have less drone then factory mufflers at that 1500rpm lug spot and actually are relatively quiet in general unless you hit the loud button Thx John in Edmonds WA february 2014

  3. Look and sound is awesome!

    Posted by Unknown on 17th Jan 2014

    I am so glad I went with the 5" option. Sounds awesome! Craftsmanship is second to none. Now it actually sounds like a wrx!

  4. Great sound/looks at a great price!

    Posted by Unknown on 5th Dec 2013

    5 inch muffler with 4 inch double wall staggered tips. I ordered these for a buddy and got them installed for him, so I will speak on his behalf. My main concern was finding a relatively quiet exhaust, but by no means as quiet as stock. It was actually a bit louder than I expected, but produces more of a growl than the bass sound of the stock exhaust. Install produced a few problems. I had them installed at my local Subaru dealer, only to have them leave the outer tips nearly touching the bumper (we are talking millimeters here). I brought it back to them after voicing my concerns to Nameless. I must say, the customer service is absolutely phenomenal at NP. I can not thank you guys enough for the help. I called to ask if the 4 inch tips would fit properly in the rear valance of the sedan STI, and received several detailed pictures within minutes of my call showing the exact model exhaust fitted onto the car. Also, after realizing that my exhaust looked nothing like the pictures NP provided, I called them and received detailed instructions on how to fix it. Not having the tools nor a jack, I brought it back to Subaru and told them exactly what I was told by NP. The guys at NP were even so kind as to actually speak over phone to the mechanic who had fitted my exhaust incorrectly and walk him through how to fix it. The only bump in the road was how rude and ignorant the people at the Subaru dealer were being! It was literally a five minute fix and they made a huge deal of the thing. They told me that the instructions I was given were not possible, and the guy actually refused to talk to the customer service rep from NP! After someone actually talked to the NP rep, they performed the corrections, which were in fact quite simple. It worries me that I bring a car to a Subaru dealer hoping to get high quality work and get service from people who seem like have never seen an STI! Anyways, this all takes away from the amazing quality and help that is delivered by Nameless Performance. At around $600, this is a great deal if you are trying to find a great looking, high quality exhaust.

  5. Nameless delivers.

    Posted by RB on 1st Oct 2013

    The guys at Nameless really know what they are doing. The craftsmanship that goes into these products is simply top notch, and you recognize a superior quality piece upon opening the box.

    I was actually a little startled when I first started the car after install, it being a little louder than I expected. However, I quickly realized that it's not so much an increase in volume as it is a more defined note - much crisper than stock, which just sounds dull and droning. After testing for a few days, I have zero regrets with this purchase and am amazed at how a muffler swap can breath such new life into the car. Downshifts are so satisfying!

    Anyone looking for a high quality piece with perfect tone and easy configuration for future additions (mid-pipe, downpipe, etc.), look no further. I am happy to support the stand-up guys at Nameless who provide excellent customer service and beautiful products.

  6. Very promising

    Posted by Calvin Pang on 14th Sep 2013

    After of 3 months wait I finally got my 3.5" staggered single wall tips with 5"muffler axleback. great quality and sounds superb. Its a must do if you want that genuine Boxer sound!

  7. Best purchase ever

    Posted by bojangles on 13th Sep 2013

    This axle back is by far the best purchase I've ever made. I was a little worried about getting the black because I couldn't find any pictures of it against the WRB, but it looks awesome. The sound is amazing. Just enough grumble but absolutely no drone (stock dp and mid).

  8. There's that rumble I been dreaming of..

    Posted by Alex on 10th Sep 2013

    The guys at Nameless have been really helpful through the whole process. The product took about a month to get to me and it was way worth it. The quality is amazing and install was cake walk, just use a pair of ramps and you are set. Now for the sound, at start up it is pretty loud, but after the car is past start up, there is a beautiful rumble to it. It is louder than I thought it would be(which I really didn't want) but it is an amazing sound and I am more than happy with my purchase. I'm saving up for setting it up to a full turboback. Can't wait. Nothing compares to Nameless. Thanks for everything guys and a great product

  9. Perfect sound for an adult.

    Posted by David on 19th Aug 2013

    This is the perfect sound from an exhaust for someone who is in the over 40 crowd. Nice deep tone and close to normal for normal driving and a nice growl when you open up the throttle. Only draw back was long wait to receive it. It is well worth the wait though.

  10. Everything and more!

    Posted by Nevin on 18th Aug 2013

    After listening to numerous clips on youtube and reading reviews i ordered the 5" muffler setup. The sound is AMAZING and completely lost on youtube videos even when recorded with a good mic and played back on a quality system. Do not hesitate this sounds amazing. Next up i have to install my downpipe which has to sit in the garage until my v3 accessport arrives.
