PERRIN Exhaust Systems produce an aggressive tone without being overbearing for street use. Made from 304 stainless steel with a brushed finish, PERRIN Exhaust Systems will look good and last the lifetime of the car, backed by a lifetime warranty.

3.5″ Slash Cut Tips
An over-sized 3.5″ slash cut exhaust tips add 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.

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, 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.

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.

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.

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