 Product Description

Our 2015+ WRX & STi Midpipe features a 3" primary circuit with a unique Y section that ensures optimal flow transition from the main 3" circuit into our 2" rear circuit axleback exhaust.  The Y features a stepped design which puts larger diameter tubing at the transition of gas flow as the exhaust is split from the main circuit into each of the rear circuits of the system with a triple stepped graduation to the 2" rear circuit.  This design builds higher torque than any other catback on the market while building the same horsepower numbers that are seen in most higher end catback exhaust designs.  Additionally, the 2" secondary circuit design biases the exhaust sound frequency to ensure drone-free operation.

This midpipe is the forward component in our Catback Exhausts for the '15+ WRX & STi Sedan.

Design
The midpipe is a 3 piece design featuring latch-over V-band clamps at the two connections in the middle of the system with factory fitting 3" flared flange at the forward (downpipe) end and factory fit flanges at the axleback section.  These latch over style V-band clamps allow for easy installation and the three piece design and positioning of the V-band flanges in the system allows for maximum adjustment for ground and vehicle chassis clearance.  The midpipe ships with a proprietary 3" donut gasket which allows you to connect the larger midpipe main circuit to your factory downpipe or to a Nameless Performance 3" downpipe with no restriction to flow between the 3" downpipe circuit and the 3" midpipe primary circuit.

The system is built entirely of T304 stainless steel to ensure top quality corrosion resistance and long life of the product.

Performance
When coupled with any of our axleback exhaust designs, the system has shown gains of up to 34ft lb of torque at the wheels and 22whp on the EJ series STi and test data should be released for the WRX shortly.

Installation Instructions:

Installation Guide - Axleback/Catback/Midpipe

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. A must have hands down!

    Posted by on

    So, this is my third product I have purchased from nameless and let me tell you they NEVER disappoint! i had purchased first, the axle back muffler deletes. Wasn't giving me that deep rumble tone (IMO) that I was looking for. And at that point, I had already done a lot of extensive research on exhausts. I was a bit hesitant, like everyone else, to purchase the Nameless midpipe. Saved up a bit and bought the midpipe like 2 weeks ago. This is a must have for anyone that has the axle back muffler deletes! The entire catback system (together now) was the sound I was searching for! It has the perfect deep tone coming from the midpipe and the perfect mid-high tone coming from the muffler deletes. And I'm super picky when it comes to sound and craftsmanship. This here is the perfect blend of sound. Nasty (meaning good) on the cold start! Excellent tone between 2k and 3500. 3K i believe is the sweet spot. Not too annoying but gets heads turning. Once you punch it past that, you get the sound Subaru was intended to make. No droning in cabin. You rear passengers might have something different to say about that, though. Lol. Followed by some backfiring when either up or down shifting. I realized when I use my Subaru in (I) Intelligent Mode, the exhaust system is a tiny bit quieter. When used in (S) Sport mode or (S#) Sport Sharp, the exhaust sounds a bit louder. I recommend going to an exhaust shop to have it installed. Installation can be a bit tricky. I mean, if you have a few bucks laying around, just have them do it. The verdict? Very very pleased with this. This is the system to get. Couldn't be more happier with this set up. Customer service was great. Which is why I continue to purchase from Nameless Performance.


  2. Good quality.

    I think is a simple less than an hour job. I already had the no mufflers nameless axleback and it did tame the sound, maybe because of the resonator. But overall a great craftsmanship.


  3. Awesome Exhaust!

    First of all the Customer service here at nameless was far beyond what was expected. The product itself is well beyond the quality of the competitors. the mid pipe conversion fits perfectly with the stock down pipe and the axle backs. i now have the full turbo back exhaust and the performance is well beyond what was expected. i would definitely recommend this product.


  4. The best exhaust around!

    Posted by on

    I have had the axleback exhaust with 4" mufflers for about 8 months. Finally decided to upgrade to the full catback by adding the midpipe. The welds looked beautiful and everything was packed safely. Shipping was incredibly fast too! It's hard to describe how amazing this setup sounds. Check out my video on youtube for a quick cold startup: https://www.youtube.com/watch?v=ggIuHoO8xIA


  5. Nameless Midpipe and Axleback deletes

    Posted by on

    LOUD very very LOUD. If you want the crackle between shifts and don't care about the attention this is for you. Lovely welds quality work. Great customer service. Very happy with my choice!


  6. A little struggle for a great result!

    Posted by on

    It took me and a friend almost two hours to get the midpipe attached. We ran into a problem with it touching the driveshaft, then we had to maneuver the axle backs properly so the exhaust tips were evenly spaced. But once we got it all figured out the exhaust is amazing! Can't say I notice any power gains, because I only have the catback and have not put my car on a dyno. But the sound is orgasmic! Nice deep rumble, pops and crackles on downshifts and sometimes between shifts, and it's not super loud (with the 4" muffler axle backs) I would highly recommend this to anyone with a STi!


  7. perfect for '15 WRX

    Posted by on

    Amazing quality, as always. Not gonna lie, removal of the stock midpipe and installation of this one was a bit of a hassle with a jack/jack stands. The WRX has pretty low ground clearance, you really need to jack it up high to get underneath the middle of the car.

    I'm so happy with the end result though, so it was worth it. I started with just the 5" muffler axlebacks which were great, and helped with the lacking exhaust sound. The midpipe adds a really nice, elegant, bass note, that is louder when you need it, but totally doesn't drone on the highway. There's a definite boost in torque too. I'd definitely recommend this or the whole catback if you haven't swapped your axleback yet.


  8. Best exhaust I've ever owned
