Description
Our Midpipe for the 2015-2021 WRX & 2015-2018 STi 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 2015-2021 WRX & 2015-2018 STi.
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:
Upgrading to our long lasting Nameless Performance urethane exhaust bushings from the factory rubber bushings is highly recommended. The softer rubber factory bushings are overly flexible and if you race your car or spend time at an incline off-road, the exhaust can "wag" left to right which sometimes causes noise or the tips to touch the rear bumper on Outback applications. When this happens there is a chance your bumper can be damaged or if you have a hitch or any other accessories can cause annoying sounds. The best way to avoid this is to use our urethane exhaust bushings to hold the exhaust in place. These upgraded bushings are not necessary to install our exhaust systems but for the small cost of upgraded units, it is an excellent idea!
- Add 2 Bushings to your cart: 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.
- Add 4 Bushings to your cart: Replace all 4 rubber bushings on the axleback portion of the exhaust. Recommended for people drive off-road or who race their cars often.
- Add 5 Bushings to your cart: Replace all 5 of the factory rubber bushings from the midpipe back. Recommended for those who are hard core off-roaders, autocrossers or circuit racers.
