 Product Description

We are proud to announce our Catback exhaust for the 2008-2014 Subaru STi Hatchback/5 Door. Our goal with this project was to develop a reasonably priced, manufacturable high flowing, low-drone design when combined with our 3″ mandrel bent divorced downpipe

The result was a 3″ into dual 2.25″ axleback featuring quad exit tips, all stainless TIG welded construction that is Handbuilt to Order in America. Using well designed designed dogleg y’s on each exhaust tip for a flush and tucked fit in the rear bumper valence cutouts without risking overheating or melting the valence. This design also has the benefit of perfectly even flow from the right to left as well as out of each of the four tips. No biased flow here like you may find on muffler designs that use a baffled internal resonance chamber.

The Midpipe is a free-flowing straight-through 3″ mandrel bent system that utilizes one 3" resonator to smooth out any rasp. Our design uses a v-band connection in the rear to allow the user to fine-tune the fitment of the exhaust. The MidPipe also uses a flex coupling near the AxleBack connection flange to eliminate exhaust “wag” found in other exhausts.

The CatBack system includes all required hardware, a 3” aluminum gasket with a raised sealing ring to provide a positive seal at the AxleBack joint, and a 3” donut gasket similar to the factory gasket. We use a factory style donut gasket due to the superior sealing ability of this style of gasket.

Configuration Options:

For comparison purposes we will use a scale of 1-10 for volume, 1 being stock and 10 being no mufflers.

  • 5" Mufflers: This is our new design that uses our in-house mufflers. We build each of these mufflers by hand here in our shop with our usual attention to detail. This "Less Quiet" version uses 2 mufflers that measure 6" long and 5" outer diameter. Despite their small size, these mufflers are extremely effective. This is about a 5 on the scale.

  • 4" Mufflers: This is our new design that uses our in-house mufflers. We build each of these mufflers by hand here in our shop with our usual attention to detail. This "Louder" version uses 2 mufflers that measure 6" long and 4" outer diameter. Despite their small size, these mufflers are extremely effective. The 4" mufflers are louder than the 5" mufflers. This is about a 7 on the scale.

  • No Mufflers: Finally, the sound of the Sedan Muffler Delete for the hatch! We have had people banging down our door for this since we released the original muffler delete for the sedan. This is a 10 on the scale.

Please keep in mind that we only trust extremely skilled craftsmen to build your parts. Qualified welders who are able to meet our standards in both fit and finish are extremely hard to find and as a result are very expensive. The end result is the highest quality, most functional product that is also a work of art worthy of a gallery.

Recommended Add-Ons:

Urethane Exhaust Hanger Bushings

Our urethane bushings hold your exhaust in place better that the factory rubber bushings and are highly recommended if you race your car or enjoy spirited driving. During hard cornering the exhaust "wags" left to right which sometimes causes the tips to touch the bumper. When this happens there is a chance your bumper can be damaged. The best way to avoid this is to use our urethane exhaust bushings to hold the exhaust in place.

  • 2 Bushings: Replace the two bushings at the rear of the car closest to the bumper. Recommend for those who either drive hard on the street or race occasionally at the track.

  • 4 Bushings: Replace all 4 rubber bushings on the axleback portion of the exhaust. Recommended for people who race their cars often.

  • 5 Bushings: Replace all 5 of the factory rubber bushings from the midpipe back. Recommended for those who are hard core autocrossers or circuit racers.

  1. Great workmanship and fantastic sound.

    Posted by on

    Great product and highly recommended. This is on my 2013 STi hatchback with EL headers, 5 inch muffler, 4 inch tips. Beefy sound and doesn't drone at all to my ear.

  2. Phenomenal

    Posted by on

    Works perfectly. It bolts directly to the old downpipe and follows the car exactly how the stock one did so installing it was very easy. As for the sound? Beautiful. The drone is nothing compared to most other catbacks and even some axle backs. When it's idling and at low rpms it has the classic boxer rumble and when you step on it the sound is magnificent. I would highly recommend this to anyone considering an exhaust system.

  3. Worth every penny.

    Posted by on

    Went with 4" double wall staggered with 4" mufflers.

    I have no words. See all other positive reviews. I agree with it all.

    But seriously... buy this exhaust. Great company to work with, and the workmanship is a breath of fresh air. You will not be disappointed!

  4. Dat rumble

    Posted by on

    This exhaust sounds amazing. With the larger muffler it is still loud when you cold start and when you accelerate hard, but is classy and pretty quiet at idle after a quick warmup. This coupled with an invidia catless downpipe got me to 275 HP to the wheels after a tune at snail performance. 100% worth the wait

  5. Best exhaust hands down

    Posted by on

    I had the Invidia N1 Dual CB on my 14 wrx and I liked it but drone was way to much for me and I wanted the quad look back. I was hesitant due to the money factor and this exhaust, but I did it anyway. I was more than happy when I received it, craftsmanship is amazing, welds are spot on, they include everything you need to mount it perfectly, even a donut gasket that most other brands do not offer. I got the 4in muffflers and resonators and its sounds perfect, no drone whatsoever and it has the subie rumble from hell now. Fits my back exhaust exit of my hatch perfectly too. Thank you for an amazing exhaust Nameless!

  6. The most perfect exhaust, ever.

    Posted by on

    2012 WRX, 3.5" staggered single wall with resonator and 4" mufflers.

    I've had this exhaust now for two months now and if you want a short and sweet review here it is: scroll back to the top and buy this.

    First off, the guys here are super helpful. Anyone who has had a hatch/wagon that had the muffler fall off will tell you...the sound inside can be a little bit much over time. So when I see a no muffler option, obviously I wanna take it because I routinely make poor decisions. But seriously, I didn't wanna ruin the enjoyment I get from my car so I called 'em up and asked what they thought. For anyone reading this review and is curious, what I was told and what sold me on the 4" mufflers was the guy I talked to telling me that if I ended up getting no mufflers and went to a downpipe later on, the sound would be brutal and probably ruin the fun of driving.

    The quality of this exhaust is incredible. The welds are perfect, but more importantly, everything fit up perfectly. To make things even sweeter, the axleback pipe is like a symmetrical work of art. I'm a full supporter of small companies like this one and with good reason, when they produce products of this quality.

    Oh yeah, it sounds great and the gains are noticeable with or without an AP. People are always complimenting the superior sound over their setup.

    I'm not a big guy, but it took me an hour to remove the old exhaust and bolt up this one by myself.

    I think that covers everything...

  7. Worth the wait!

    Posted by on

    Being a person who suffers from a need for instant gratification, I can tell you it was absolutely worth the wait. I didn't have to wait long but I'm glad I did...

    The quality of the welds is superb, a true work of art. Fitment was fantastic. Using the "V" clamp for adjustability was pure genius! Customer service was top notch, I changed my order up mid way without issue and still received my parts in an expectable amount of time. Really pleased with my dealings with them personally.

    Now for the Sound...Pure sex! I went with 3.5" double walled (which filled out the valance perfectly), staggered, 4" mufflers, resonated. At first it was loud, a good loud. The kind of loud that makes you giggle like a child. Wonderfully low boxer grumble at idle. ASBSOLUTELY NO RASP WHATSOEVER. No tin can sound here folks, just pure heaven. Honestly what the car should sound like from the factory. Once a nice layer of carbon built up on the inside it quieted down quite a bit. Very happy and will recommend and purchase from them in the future. Fan for life.

    I wish I was a professional author so I could accurately portray how amazingly perfect this exhaust is.
    Keep up the good work.

  8. The mean catback

    Posted by on

    I picked up a catback for my 13 STI hatch with a resonator, 4" mufflers, and 3.5" single wall tips. Great craftsmanship, the welds are flawless, and the quality of the build is top notch. At cold start it's a little loud, but quiet when warmed up. From what I can tell if you stay out of the throttle it doesn't attract too much attention, but at WOT it will rock you socks off and definitely turn some heads. Altogether it's the best exhaust I've invested in. Nameless puts a good product out and backs it with customer support that anyone's company would envy! The look of the 3.5 in tips just falls in perfect with the clean rear end of the sti hatch. Thank you Ryan for your help with my build.
