At Nameless Performance we are excited to offer our Subaru Ascent exhaust system in a full cat back 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 cat back 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.  


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.
