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.

Downpipe Construction
Crafted from 304 Stainless Steel, PERRIN down pipes use mandrel bent 3" tubing, insuring a streamlined exhaust flow. Making crisp boost and throttle response when needed. View the Downpipe here.

High-Quality Catalyst
This PERRIN downpipe uses a 200cell per inch metallic substrate catalytic converter. Unlike the OEM ceramic brick style catalytic converter, our converters have high flow rates and are guaranteed to take the extreme heat produced by high horsepower Subarus.

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.

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.

Finish
The PERRIN exhaust systems comes in a brushed finish, we also offer a stealth black powder coat option. This will give you a stealth look and hide your aftermarket exhaust system.
