2011-2014 STi/WRX Sedan Quad Tip AxleBack Muffler Replacement w/ 4" 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.

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.

Brushed T304 Stainless Steel with Polished 304 Stainless Tips. +$0/pair.

Coating Options:
Bare:  Just bare, TIG welded T304 Stainless Steel. +$0/pair

10% Gloss Black Powdercoating (masked polished tips):  This high temp powdercoating is made for exhaust sytems and is an industrial finish.  Parts are prepped through multi step blasting, etching and cleaning process prior to powdercoat for a rust free substrate layer and durable finish.  Color is almost flat black, but has just enough gloss in it for ease of cleaning.  +$90/pair

10% Gloss Black Powdercoating (black tips): Same as above, but tips are not masked, fully blacked out.  +$60/pair

  1. Awesome

    Posted by Unknown on 19th Apr 2014

    Great mufflers awesome sound

  2. Absolutely Perfect!

    Posted by Mike on 2nd Apr 2014

    First of all, I cannot say enough about Nameless and their customer service. Living in Canada, the current dollar conversion wasn't great and was leading me away from the purchase, however, Ryan did absolutely everything possible to get me a great deal and made sure it worked within my budget!

    The package came earlier than expected and everything that I had order was included and nicely packaged. I heard rumors of the install taking only 20-30 minutes, and was a little skeptical. I have never done my own work on my car (2014 STi), however this time I gave it a shot. About 35 minutes later I had the exhaust completely installed and was driving to school. IT SOUNDED PERFECT! No droning at highway speeds, and at idle it's a deep, not too loud rumble. Nothing that would piss off the neighbors. Don't get me wrong though, when you go WOT you hear the full sound of the engine and it sounds mean. I could not be more satisfied with the quality of the exhaust, the sound, the ease of install and the hard work done by the guys at Nameless to get me this product.

    I would recommend this to ANYONE looking to hear the true sound of their Subaru and believe me when I say you will not regret it!

    This thing sounds so amazing. I roll with all 4 windows down to hear the true beautiful sound that emanates from these pipes. With them up you'll think it sounds ok, but down it's perfect. It just bellows out the most intimidating, powerful sound ever. Take it through a tunnel and you'll DIE with happiness/laughter, I know I did! Cold starts are a little loud but again if you do it with all the windows down it's really not too loud. Best money I spent on the car definitely.

  4. Don't waste time to decide if you want this!

    Once you order and install it, you'll be glad you purchased this axle back. It sounds amazing when you accelerate and brings out the true sound of a boxer engine! Also customer service from Jason and Ryan is very helpful and informative!

  5. Sounds Great

    Posted by Anthony on 2nd Sep 2013

    Took a little over a month for them to arrive when I placed the order. Install took about an hour but it was a pretty simple job. They look and sound great. If you're unsure whether or not the muffler delete will be too loud I recommend you get it anyway. Personally I'd say the exhaust is loud but not loud enough. For a few days it may seem extremely loud until you get used to it and realize it isn't so loud at all. However, if you just want to improve the sound of your car with moderate loudness this is the perfect product. It sounds pretty much stock until you are above 3000 rpm and there is little to no drone. The customer service is great and they are quick to help you with any questions or concerns you may have.

  6. Canadian

    Everything was good, took a bit to get here but other then that it's a good product.

  7. Amazing

    Posted by John on 26th Jun 2013

    Just amazing... all I can say. I want to drive everywhere now!

  8. Excellent service, Amazing product

    Posted by Jordan on 1st May 2013

    I had been on the fence about buying an exhaust for my WRX sedan. After a lot of thought I leaned towards Nameless. I hadn't decided fully until I received an email from John letting me know that they were about to make another run on sedan exhausts and had a few left from the last run. He said he could give me a little discount if I was interested in one so I jumped on it. I went with the blacked out non-staggered tips, and they look BA. Since I dropped the old mufflers off already it took less than 15 mins to install. Fitment and spacing were both impeccable. I will say that the 4" system is still fairly loud though (not really to me, the wife)

    Overall I love the system. Though I see a mid pipe in my future to tame it down a little.

    Have to give a final thanks to both John and Matt for their help and service!

  9. Great service, great people and quality product!

    Posted by Elliott R. on 19th Mar 2013

    I recently purchased the 2011+ STi/WRX Sedan Quad Tip Axle Back Muffler Replacement w/ 4" Mufflers with staggered tips. I called to place my order at 12pm on Thursday, they had all the material for my order, they built exactly what I wanted and I picked them up the next day in the afternoon! Speed production! I must say the sound that these produce, is the sound that these cars should come with from the factory, great design! They have a deep rumble, not too loud, not too quiet, the perfect combination. I went to their facility to pick up my axle back and Jason invited me in, gave me a tour and shared some useful information about aftermarket parts and tuning. Everyone in the shop was very hospitable, polite and knowledgeable, just the kind of people you would want making and designing your aftermarket parts! Now back to the axle back, the welds are immaculate and they don’t show any weak spots, the tips are evenly spaced, the fitment is as good as stock, if not better. Both mufflers line up perfectly and they are even on each side! From far away they look good and up close they look even better!! I highly recommend their products because of the quality and the great customer service that Nameless performance provides. Thanks again!

    Hope this review can help future Nameless Performance Customers!

  10. I wanna drive for no reason now!

    Posted by Whiteycooper on 17th Mar 2013

    You really just can't understand until you get em. first of all, the mufflers look awesome. Made in the USA with no lack in quality control. The sound just cant be described. There are a lot of different subaru sounds, but these mufflers are disgustingly amazing. You can watch all the youtube videos you want, but its not the same. Just buy them! There isn't a better 400 bucks you can spend, I promise. I want the midpipe now, bad. Awesome customer service as well, thanks guys.
