2008-2015 Subaru WRX Sedan Cat-back

4" Slash Cut Tip

An over sized 4" slash cut exhaust tip adds an aggressive look to this impressive system. PERRIN exhaust tips are a brushed stainless steel, single wall construction and will not discolor with extreme heat.

Straight Through Muffler

PERRIN Performance mufflers have a true 3" internal diameter for uninterrupted exhaust flow. PERRIN mufflers and flange connections are 3" throughout the entire length, not necked down, for ultra smooth transitions throughout the system.

304SS 3" tubing

PERRIN Performance exhaust systems are made entirely of 3" Diameter 304 stainless steel. 304SS provides high corrosion resistance and is excellent for heat up to 1800 degrees Fahrenheit. Other manufactures may use cheaper 409 stainless steel which will rust and corrode over time but the added expense of 304 stainless steel is well worth the beautiful and long lasting finish and durability.

Adjustable Y-Pipe

Our Y-pipe splitter features two slip joints which let you adjust muffler location and tip placement to perfectly sit in your bumper cutouts.


PERRIN performance exhaust systems feature high tech v-band clamps for a perfect exhaust connection. V-band clamps are designed to hold hundreds of pounds of pressure and do so without the need for a gasket! This connection allows for a precise repeatable joint with the ability to rotate each joining connection. This allows for easy installation and alignment adjustments for a perfect fit every time.


PERRIN exhaust systems comes in a brushed stainless steel finish.


It is very important to us for our exhaust to make power, but sound level and tone should also be a concern. Our system is designed to have a low and pleasing rumble while not producing the loud, rough drone that wakes your neighbors.

2.5L WRX Catback Test

This was done on our 08 WRX running a Stage 1 AccessPORT tune; this represents exactly what we see for WHP changes on all the WRX models after installing the Cat Back Exhaust. The 5-8WHP gains we see are typical on both the 2.5L and 2.0L WRX after installing our 3" cat-back exhaust.
