Skunk2 MegaPower R 02-05 Honda Civic Si 70mm Exhaust System - 413-05-5020

A properly designed exhaust system is critical to engine performance. Skunk2’s 70mm MegaPower Exhaust system for the 02-05 Civic Si was developed with this in mind and is based off of more than 15 years’ worth of racing experience. Dyno-proven for maximum horsepower, MegaPower R cat-back systems are constructed of T-304 stainless steel, are robotically TIG welded, and feature CNC mandrel bends for a precise fit. Designed for naturally aspirated engines featuring higher compression, aggressive camshafts, and racing headers as well as for mild turbocharged applications that require more exhaust flow than Skunk2’s 60mm MegaPower Exhausts provide, MegaPower R Exhausts allow engines to breathe more efficiently and produce more power thanks to larger diameter piping. MegaPower R Exhaust systems were designed for maximum flow and power, featuring oversized tubing and mufflers, which results in a significantly louder tone when compared to 60mm MegaPower systems. Featuring Japanese-spec, Super N1 styling, MegaPower R Exhaust systems generate more horsepower by optimizing engine airflow and volume through carefully selected, application-specific tubing lengths and diameters and increased wave scavenging effects for more horsepower. CNC mandrel bending allows for a constant tubing diameter throughout the bend, which results in precise fitment as well as improved exhaust gas flow. Each system is fitted with a resonator, includes stainless steel flanges, and is finished off with a straight-through, low-restriction racing muffler for uninterrupted flow. Each fully polished muffler is mated to a 110mm polished tip with its own acid-etched MegaPower badge and serialized nameplate. A Skunk2 removable silencer and all necessary hardware are also included. Skunk2’s MegaPower Exhaust lineup is based off of the same systems we custom build for our road racing and time attack vehicles.

Exhaust systems are a great way to enhance the looks, sounds, and performance of your vehicle.

Replacing the OEM catback on your car is one of the first modifications we recommend to any new car enthusiast. Replacing the OEM catback with an aftermarket exhaust system is a great way to increase horsepower, style, and the sound of your car.

All Skunk2 products are carefully planned and designed in-house using the latest computer simulation and modeling techniques, followed by careful testing in controlled laboratory environments using state-of-the-art equipment. Each product is then subjected to rigorous dyno, street, and race track testing to ensure proper performance in the most extreme conditions. For these reasons, top street cars and race cars worldwide rely on Skunk2 products. As part of Skunk2’s commitment to developing industry-leading products, we’ve remained actively involved in various forms of motorsports through technical partnerships, sponsorships, as well as with our own race vehicles for more than 15 years. We’ve gone on to secure a number of drag racing and road racing records and championships, including earning the title of the world’s first 10-second naturally aspirated Honda. Racing provides us with the data necessary to produce high-performance parts utilizing innovative designs, advanced metal alloys, cutting-edge manufacturing methods, and stringent quality-control measures. Driven by the desire to make things go faster, Skunk2’s staff is comprised of industry leaders, racers, and enthusiasts who are passionate about what they do and understand what other enthusiasts want. Our perspective is shaped by real-world racing experiences as well as by practical science, and that's precisely what makes Skunk2 products so good. Firmly grounded in our understanding of engineering, we make every effort to embrace advanced technology. Our goal is to make performance and technology accessible to other enthusiasts through innovative manufacturing techniques. Since 1994, we’ve released a number of industry-leading products, including the first cast aluminum, high-performance intake manifold, cutting-edge composite fuel rails, and valvetrain components made from premium materials. Skunk2 is acclaimed as being the first U.S.-based sport compact parts manufacturer to offer CNC-machined, adjustable cam gears in 1995 as well as billet camshafts in 1999. As a result of continually pushing our engine development capabilities in the racing world, we’ve discovered a number of exciting “power secrets” that are incorporated into every Skunk2 product. Today we continue our tradition of creating leading-edge products through a state-of-the-art engineering and R&D department as well as through extensive engine development and testing both on the race track and the street.
