The N1 catback system is a more aggressively styled exhaust than the Q300 from Invidia. It features more straight-through, smaller muffler for a little louder note. It's also a very high flowing setup and will give you plenty of extra power and torque, especially when supported by other performance modifications. The system is a full 3" and constructed of stainless steel for a high level of durability. This sytem features a single titanium tip with a burnt blue finish and does NOT have a resonator.
