The Apex Universal muffler series is the perfect choice for those who want to fabricate a unique “one-off” exhaust either for a race car or a custom street car. Now, the racing heritage and performance power of Apex can be felt on practically any vehicle. With turbo and non-turbo applications, the universal Series provides a cost effective and versatile choice for exhaust system development. All Mufflers are constructed of polished SUS 304 stainless steel. Welding is required for installation. Brackets and hangers are not included. Horsepower gains will vary according to vehicle and exhaust piping configuration. Use of a resonator is recommended for street car applications (not included).

Due to the overwhelming popularity and benchmark standard of the N1 Mufflers, it was only natural that this muffler was offered as a universal. Now, the N1 muffler can be enjoyed on virtually any vehicle. Similar to the cat back system, the N1 universal uses premium polished SUS 304 stainless steel constructed using both robotic and hand crafted welding. Straight through design ensures maximum power on properly tuned exhaust systems. The N1 Universal incorporates a 60mm (2.36 in.) inlet and 90mm (3.54 in.) tip for naturally aspirated applications and an 80mm (3.15 in.) inlet with 115mm (4.53 in.) tip for turbocharged vehicles. Since this muffler is universal, the output angle of the exhaust can also be determined by the customer during installation. Create your own custom N1 look while enjoying the power!

Not only does the N1 Metal retain all of the performance characteristics of the N1 muffler, the N1 Metal universal incorporates an exclusive coloring process that allows Apex engineers to create multiple color variations. Available in two different colors, the N1 Metal adds an extra sense of subtle and solid power. Extremely popular on the street and at car shows, the N1 Metal is a true example of pushing the envelope in exhaust system design.
