2008-2014 WRX and 2011-2014 STi Sedan Midpipe
- Calculated at Checkout
Our 2008+ WRX & STi Sedan 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 '08-'10 WRX Sedan as well as the '11+ WRX & STi Sedan.
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.
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 when tested using a Stage 1 Off The Shelf tune as the baseline dyno pull.
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.
