Description
At Nameless Performance we are excited to offer our Subaru Ascent exhaust system in a full catback configuration. Customizable for different sound levels you can get this complete Ascent exhaust system with our 5" muffler offering a deep tone or in our more wild muffler delete variant for those who really want to amplify their driving soundtrack.
The catback system includes a midpipe and an axleback exhaust for a complete package ready for bolt-up installation to your vehicle with no cutting or welding required, a definite perk!
Our 2018+ Subaru Ascent catback 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, which comes in handy with the CVT transmission on the Ascent.
Aft of the midpipe, the axleback exhaust completes the catback, with your choice of 5" muffler or muffler delete.
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 axleback features optional mufflers which are fully tig welded in-house for a lifetime of quality performance. All flanges are precision laser cut and the tips are 4" diameter polished 304 stainless slash cut single wall designs which are built in-house and hand tig welded.
The system is built entirely of T304 stainless steel to ensure top quality corrosion resistance and long life of the product.

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. 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 4 Bushings to your cart: Replace all 4 rubber bushings on the axleback portion of the exhaust.
- Add 5 Bushings to your cart: Replace all 5 of the factory rubber bushings from the midpipe back.
