 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. Loss for words!!

    Posted by on

    So I had a megan cat back with an invidia catless dp. I replaced the cat back with all nameless... afterwards I then came in my pants! I got the muffler delete 4" tips with the midpipe. Trust me you want this exhaust!!! My car now pops and crackles in every gear up or down shifting!!! Also got a sweet beer cuzi and stickers for my car! You cant go wrong here!!! Thank You Nameless, this smile is never gonna go away!

  2. Great quality, craftsmanship, and sound, but the CBE is just not for me

    Posted by on

    I spent years wondering if I should buy this Nameless catback setup. Also debated just getting the 5" Axleback. I started with the trackpipe, but the wife didn't like it. Just another reason to hate my car, she said. My friend got the 5" Axleback for his car. I liked it quite well but still wasn't 100% convinced that it wouldn't drone. I thought it would be better than the trackpipe, at least. Well, after having a kid and losing my mind about exhaust, I finally decided to sell the rarely used trackpipe and get the catback.

    The NP Resonated Midpipe (MP) + 5" Axleback (AB) sounds phenomenal. Just dipping into the throttle sounds like the Stock MP + 5" AB at Mid-WOT - it is that aggressive. Super throaty, burbly, rumbly. The issue for me is it was 5-6 decibels higher than the road noise between 40-60mph, which is where I do most of my driving. It was creeping on 80db with light acceleration which was borderline not ok for developing baby ears. So as a compromise I decided to try a "CC Insert" - 3" 3 disc Inline Baffle. I put it in the split at the midpipe. It helped a bit, but the power loss was noticeable, I could feel the car cutting timing (live and learn). Also, the thing was, having tested just the 5" AB + Stock MP before and after, I found that was quietest and least droney setup, aside from going back to stock. Makes sense, smaller diameter pipe, faster flow, higher frequency, less audible booming. More importantly, it was quiet enough for my little guy, and I still get rumble! So I am very joyful for that. It's hard to avoid hills in VT so there's really no way to drive around drone (on flats & slight decents you can manage it with neutral throttle), but the 5" AB by itself is definitely acceptable in that regard.

    Perks of Catback (and even STK MP + 5" AB): Can actually hear the WRX now - great for rev matching, better fuel mileage (consistently 1-2mpg better, suprisingly), better throttle response, looks great, #1 in quality IMO. The NP MP + 5" AB is uber responsive to throttle inputs.

    Cons: It's obviously louder. I found that drone correlates with volume but also with Midpipe selection. Oddly others here have said the opposite. YMMV. I couldn't measure drone easily, like when you're off throttle and booming, it was the same measured volume between setups, but it sounded louder with the NP MP. Anyway, see below.

    For reference the NP MP + 5" AB was 74-80 dB around town, 90-100dB WOT, STK MP + 5" AB was 70-75dB around town, 80-95dB WOT. Highway/road noise (65+mph cruise)is 75-80db regardless of setup. I didn't bother measuring stock as it's incredibly quiet. Measured with an iphone 6, in the driver seat, and also the second row passenger seats.

    TLDR - I really love the 5" Axleback by itself. If I lived by myself I would run the NP Midpipe no question. It sounds so good, especially in spirited driving. I just had to compromise for my family. I love the Nameless philosophy, and their support. 10/10 would buy from them again.

  3. Nameless is supreme. JUST BUY IT!

    I’ll just start my review by saying if you’re on the rocks about muffler size like I was at all, stop reading and and get the deletes. I bought the catback system with 3.5 tips for my 08 STI hatch and couldn’t be any happier. I thought it might be too loud when in actuality is perfect. My neighbors don’t hate me and I’m not setting off car alarms but I 100% grab the attention of anyone in the area. It’s low and growly at idle and sounds even better on the gas. No drone while driving in the city or highway. Also the install was a piece of cake. I’m not the most mechanically inclined person and I manage Put it on in a couple hours. As an added bonus nameles was even there to help answer all our questions. It’s a huge hit with all my car friends and blah blah blah I could go on forever lol JUST BUY IT

  4. Buy it

    Ordered my exhaust Feb 24th and waited just over 2 months to get it and at first i was starting to get frustrated that it was such a long wait but it was worth the wait 110%. If your on edge about buying it don't be it is the best sounding exhaust i have ever heard and the build quality is AMAZING it fits perfectly! The only problem i have with the exhaust and this only applies if you have a 08-14 WRX hatch it hangs pretty low in the back so if your lowered you might have a bit of a problem. You might be able to get it to sit higher if you get the stiffer bushings but i just used the OEM ones. Either way this exhaust sounds amazing i have the muffler delete and would recommend to anybody!

  6. Best modification ever.

    This is the one part of the car I'm glad that I didn't decide to cut corners on. I've been listening to the many different exhaust and conclude that the nameless performance exhaust has the best sound; especially the rumble. I went with the double walled, 4" tips, no muffler set up and cannot be happier. It is loud, but it isn't too loud. One of my favorite parts of the exhaust is that it has an obvious rumble at the low end. Thanks nameless, looking to get a downpipe in the near future.

  7. 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.

  8. 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.
