PERRIN Performance has been building the normal 3" SS exhaust for quite some time and had great success with them in both performance and sound. This newer system is just like our classic 3" system but with one change to the muffler to make it even quieter. The muffler is still a 3" in and out but with baffle in the center of it. This keeps the flow to a maximum while significantly reducing the sound from the muffler.
This system was designed to give you the most power while still keeping your neighbors happy! Like all other PERRIN Performance™ Cat-Back Exhaust System, we built this from 100% Stainless steel, and with free flowing mufflers maximum exhaust flow, and keep your system lasting the life of your car. All systems mate perfectly with factory hangers, undercarriage and bumper and fit to OEM and aftermarket downpipes.
