Description
Ever have one of those days when you want to play the song of your people with your friends but you feel like you're just humming along in the audience? Well you wouldn't be the first of our customers who has wanted to get more sound out of their existing Invidia Q300, R400 Gemini or N1 exhaust by swapping to a Nameless Performance Muffler Delete Axleback. We get this question on a regular basis and hate to see our customers have to sell one product to buy another. So why not both!? Upgrading the axleback section of your existing exhaust provides you the benefit of now having two optional sound levels for your vehicle which can be swapped out with relative ease. The exhaust tips are 3.5" diameter with a neochrome finish.
Exhaust Features & Details
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:
- Configurable: Choose an option of polished or neochrome tips.
- CNC Mandrel Bent Tubing
- 100% T304 Stainless Steel Construction, Precision Fabricated and Fitted Weldment
- Hand TiG Welded
- Solid Hanger Bars
Benefits & Performance Gains
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 and a free flow exhaust design.
Beyond the sound signature and improvement in powerband, the most noticeable difference in the addition of our exhaust is the weight savings of 25 pounds!. The replacement of a packed and baffled 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.
SPECIFICS/OPTIONS
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. This configuration offers:
- 3.5" Single Wall Neochrome: This option is the same as the option above with a blue titanium oxide / neochrome finish.
Installation & Hardware: Installation is a snap with basic hand tools. Removal of the factory exhaust requires removing four bolts and four exhaust hanger bushings from the Q300 / R400 / N1 muffler. Each side of our axleback exhaust system is then hung from the factory exhaust hanger bushings and bolted to the Q300 / N1 / R400 Gemini midpipe. We provide upgraded nuts, bolts and replacement gaskets that are used when re-installing the upgraded exhaust, as well as a pair of three hole urethane exhaust hanger bushings. Hold the tips centered in the cutout in the bumper and tighten the nuts to ~20ft lb with hand tools.

My setup is a Grimmspeed jpipe, Invidia R400 midpipe (resonator still installed) and Nameless muffler deletes of course. Here’s my cold start (with stratified start). I absolutely love the setup. Surprisingly quiet while cruising but when you get much more pops when downshifting and sometimes upshifting. I’ve been wanting these deletes for a while and I’m extremely happy with my purchase!

Ok so, I have a 2009 wrx and I knew that this product would not be compatible without some modifications but went ahead and purchased anyways. Let me tell you, it was worth it. Didn't take much and super happy with the way it turned out. Will be making a custom plastic trim piece for the rear bumper to fit the nameless axle back, but for now it works. Would recommend if you're someone like me wanting the classic quad exhaust look and currently running a invidia system.

Listening intently as Subies pass by, trying to determine what instrument they’re using to create that beautiful rumble. Hours of watching reviews to help me with my decision. I needed to hear the UEL headers, as stock left me wanting more….but not too much to bug the boss at home or irritate the neighbors. Torn between 5” and 4” mufflers, I took the chance and ordered the 4” axle back. I waited patiently and when it arrived, I let it sit in my garage wondering how loud it would be, and if it would be too much. With the box opened, I unveiled a beautiful exhaust, with exceptional welds and high shine. I removed the stock and installed the Nameless. In my giddiness, I called my teenage sons to join me upon initial turn on. 3…2…1. “Grrrrrumblegrrrrumblerumble”…. Instant smiles…but zero regrets. “Not too quiet, not too loud, just right” In 1st thru 3rd the tone is low and deep…with zero raspiness. At highway speeds, no drone and just the right amount of rumble to not overpower radio and conversation. At idle at stop lights, quiet…until the green light awakens the motor…. Thanks for a great product. Smiles every day… Peace out…

Track pipe install was extremely easy. Bolts right up to the nameless midpipe. Sound is aggressive but not annoying. Really screams at WOT, but a nice hum and not overboard when daily driving. Another great performance and why I've been rocking with them since my first 2015 WRX. For what it's worth, my 2019 is equipped with the original turbo back exhaust I first bought for the first WRX and have moved from vehicle to vehicle. Nameless can't be beat.
