Material: 304 Stainless Steel

3.5″ SLASH CUT TIPS
Over-sized 3.5″ slash cut exhaust tips add an aggressive look to this impressive system. PERRIN exhaust tips sport a more heat-resistant brushed finish compared to the rest of the exhaust system and are of a single wall construction that will not discolor with extreme heat.

STRAIGHT THROUGH MUFFLER
PERRIN 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 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 it for the beautiful, long lasting high brushed finish and durability.

V-BANDS
PERRIN 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 and repeatable joint with the ability to rotate each joining connection. This makes installation much easier 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.

FINISH
The PERRIN Exhaust system comes in a brushed stainless steel finish.

SOUND
It is very important to all of us for our exhaust to make power, but sound level and tone are also important concerns. The PERRIN system is designed to have a very mellow and pleasing note while not producing loud “farty” sounds that wake the neighborhood producing levels of noise that could be described as being antisocial.
