Perrin PSP-EXT-305BR Cat-Back Exhaust System (WRX/STi 01-07)

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.

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 high polished, single wall construction and will not dis-color with extreme heat.

V-Bands

PERRIN performance exhaust systems features 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.

Finish

The PERRIN exhaust systems comes with a brushed stainless steel finish.

304SS Tubing

PERRIN Performance exhaust systems are made entirely of 304 stainless steel, inside and out. 304SS provides high corrosion resistance, and is excellent for extreme heat up to 1800 degrees. Other manufactures and OEMs, will 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 high polish, and durability.

Sound Clip

It is very important to us for our exhaust makes power, but sound level & tone should also be a concern. Our system is designed to have a very mellow and pleasing note while not producing loud "farty" sounds that wakes up neighbors.
