Overview

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.

Jump To

Sound

It is very important for our exhaust systems to make power, but sound levels and tone are also very important. Our resonated system is designed to have a mellow, pleasing rumble at lower RPM’s and light throttle. When driving aggressively, the system transitions into an aggressive tone that every sporty car needs.

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 resonated exhaust system and are of a single wall construction that will not discolor with extreme heat.

Straight through muffler

The PERRIN mufflers in this system are a straight-through design with an internal “Y” for high flow potential that works with all power levels.

304 stainless steel tubing

PERRIN Exhaust systems are made entirely of 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.

Connections

PERRIN Exhaust Systems use a few types of connections, all with a specific purpose. Flat flange connections provide a great seal and are ideal in sections that do not need adjustment for installation. V-Band connections provide a high pressure seal that allows for rotational adjustment. Slip fit connections provide both rotational and longitudinal adjustment to allow for fine tuning of final fitment and tip placement.

Adjustable Y-pipe

The Y-Pipe in this resonated exhaust system transitions the exhaust from 3.0” to dual 2.25” to go to each muffler in the dual muffler system. Each 2.25” tube also has a slip fit connection that allows fine tuning of the muffler and tip placement to get the perfect look.

Finish

This PERRIN Resonated Exhaust System comes in a brushed stainless steel finish.
