PERRIN Quad Tip Axle-back Exhaust System

We worked hard to design mufflers to meet the demands of our clients and fit the back of the newest Subarus. After many months we feel that perfection has been achieved.

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

Although the muffler flanges are smaller at the connection to the Y-pipe, with there being two mufflers and two connections, you get more than 4" of combined internal diameter. This results in uninterrupted exhaust flow for ultra smooth transitions throughout the system.

304SS 3" 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.


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


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.
