High Tech Mufflers

This PERRIN Performance muffler has a true 3" inlet pipe that carries exhaust into a center chamber before being distributed to, two 2.25" exhaust pipes which continue on to the tips.

3.5" Slash Cut Tips

The PERRIN hatch-back exhaust features 4 slash cut exhaust tips add an aggressive look to this impressive system. PERRIN exhaust tips are high polished, single wall construction stainless steel 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.

08 STI Catback Dyno Test

This test was done on an 08 STI that was running our AccessPORT Stage 1 mapping. We swapped out the exhaust in roughly 5minutes and re-dynoed the car to find 10WHP and 10ft-lbs of TQ from the catback. So not only does this add some really cool sounds but also a bit of HP, all while increasing your fuel economy.
