Our customers have spoken, over and over and over again and we have listened and taken action. A vast percentage of 2015-2018 WRX and STi vehicles ship with the SPT or 'STi Performance' exhaust system. *NOTE This does not fit the 2019 STI or the Type RA Exhaust. While this exhaust connects to the factory downpipe and fits the factory bumper, the routing and flange locations are not the same as the OEM exhaust system. The result is that many owners of this exhaust want more sound and exhaust tone and the only means of achieving that is to sell the entire exhaust and purchase a different one.
After hundreds of requests for an upgrade to the STi Performance / SPT Exhaust system, we decided to get one of these systems in and give it a run around the block and see what people were on about. What we learned was that peoples interest in a replacement for this exhaust were incredibly valid. The 'STi Performance' exhaust system has a very odd sound signature. While it has very little sound at idle and low RPM, once it achieves cruise RPM's it tends to have a pervasive drone, which intensifies as throttle is applied, and then goes away entirely leaving very little sound of the exhaust above 5000rpm at wide open throttle. Seemingly the inverse of what most people want out of a performance exhaust, we took it upon ourselves to design a muffler delete and do extensive testing of that design. Lo and behold, we end up with an exhaust that has no drone at cruise, a nice sound at idle and tip-in with a more aggressive sound above 4500RPM at heavy throttle. And all able to be directly bolted up to the STi Performance / SPT midpipe at a reasonable price point.
Featuring bolt-up factory fit flanges and hangers and manufactured in our facility in Woodland, Washington, USA, we take pride in the details of our exhaust systems and invest the best into what we build for our customers:
A simple modification like the replacement of the back muffler box on a car can transform the day to day driving experience for the owner of the vehicle, and this exhaust is no different. We love to claim that the first and foremost benefit to our exhaust systems are that they sound incredible and really make driving more enjoyable. Baffled/chambered mufflers are an amazing invention of science, with the ability to cancel specific frequencies of sound to provide a near silent operation. For those of us who are enthusiasts, however, mufflers and resonators that are designed like the factory ones are provide us with zero feedback. Switching to a muffler delete promotes more tone across the powerband while eliminating the engineered drone associated with the STi Performance / SPT exhaust in the midrange.
Beyond the sound signature and improvement in powerband, the most noticeable difference in the addition of our exhaust is the weight savings of 23.3 pounds!. The replacement of a baffled rear muffler with a straight section of tubing or straight through muffler design generally nets 8-12ft lb on the STi and 6-8ft lb on the WRX.
Tip Configuration: We offer this axleback exhaust with 3.5" Single Wall tips to achieve a larger than stock sizing on the tip without being oversized. Optionally we offer two color configurations
Installation & Hardware: Installation is a snap with basic hand tools. Removal of the factory exhaust requires removing six bolts and four exhaust hanger bushings from the factory muffler. Each side of our axleback exhaust system is then hung from the factory exhaust hanger bushings and bolted to the STi Performance Exhaust midpipe. We provide upgraded nuts, bolts and replacement gaskets that are used when re-installing the upgraded exhaust. Hold the tips centered in the cutout in the bumper and tighten the nuts to ~20ft lb with hand tools.
We recommend choosing standard FedEx Ground shipping for a 1-5 day turnaround time depending on your location. Shipping prices range between roughly $30-45 for ground shipping to the lower 48 states. International and Alaska/Hawaii rates may vary. You can check your direct shipping cost by putting the parts in the shopping cart, choosing 'view cart' and then estimating the shipping using the tools in the cart. We also offer USPS Priority Shipping as well as a FedEx 2 Day and Overnight option, but generally recommend that our customers wait a few more days and invest that extra money into their car.

Just got it bolted on and it’s a world of difference, sound is phenomenal but not so obnoxious that you can’t drive normally. At idle it has the nice subie rumble and doesn’t sound raspy or distorted. Really kicks in at WOT over 4000 rpm. Overall great quality and very happy with the purchase. Thank you!

I spent $1300 on that stupid SPT/STI performance exhaust straight from the dealership, installed. Worse decision of my life and I could’ve spent the money and bought another full catback for cheaper with better sound quality. After finding out Nameless offered the spt deletes, I ordered it. Took about three weeks but it was well worth it.
The muffler sounds amazing and really starts to hum at about 4000rpms. I HIGHLY recommend this if your WRX/STI came with that lame spt performance exhaust!!!

All the way from the packaging to the final install test. Nameless can’t be beat. Just like the description says this adds that missing rumble from what the performance exhaust was missing stock. Couldn’t be happier with the figment and the sound.

I bought this because I wanted to make a lot of pops. Ever since I put these on my car will pop when doing a rev match downshift or between gears at full throttle. I get a crazy amount of attention. These are kinda loud but not crazy loud. I can see myself being ok doing road trips with these on.

This makes the car sound more aggressive. Quality is good and the neochrome tips make the car around out more. Sound is awesome, car looks sexy and at the same time it reduced some weight. It’s all love for this exhaustt!

Anyone who has the Subaru SPT Performance exhaust system knows how disappointing it is, basically the opposite of what you would want from a performance exhaust. This muffler delete system makes the SPT exhaust what it should be, I was completely blown away with how good my WRX sounds, great sound during cold starts, it's loud but not over the top, very tasteful It far exceeded my expectations and im very happy with it, would definitely recommend it. Much credit to Nameless for another amazing product.

Just the right volume, sounds great, easy to install, really emphasizes the exhaust pops, and even gets a little more boost out of my turbo due to less pressure in the exhaust system. Props to Nameless for pioneering this system.

Very nice axle back system, flawless construction, fast shipping same day. Makes the wrx sound how it should stock, loud on high idle and nice pops when downshifting or slamming through gears. Neochrome tips look fantastic! Very impressed.
