What is the main benefit of the 76mm piping on this exhaust system?

The larger 76mm diameter piping allows for significantly increased exhaust gas flow. This is particularly beneficial for heavily modified naturally aspirated engines or turbocharged applications that demand more volume than smaller diameter systems can handle, leading to more horsepower.

Does this exhaust system come with everything needed for installation?

Yes, this MegaPower RR exhaust system includes all necessary hardware for installation. It is designed as a bolt-on system that works with the factory mounting points, so no additional welding or fabrication should be required.

How loud is the Skunk2 MegaPower RR exhaust compared to other systems?

The MegaPower RR system is designed for maximum flow and power, featuring oversized tubing and mufflers. This results in a significantly louder and more aggressive exhaust tone compared to other MegaPower systems, offering a distinct racing sound.

Product Details

If you're looking to get the most out of a heavily modified or turbocharged 2006-2011 Honda Civic Si Coupe, a high-flow exhaust system is a critical piece of the puzzle. The Skunk2 Racing MegaPower RR 76mm cat-back exhaust is designed specifically for these applications, allowing your engine to breathe much more freely than stock. This system is built upon over 15 years of racing experience, aiming to unlock maximum horsepower and torque.

Constructed from T-304 stainless steel, this exhaust system features robotically TIG welded seams and CNC mandrel bends. The larger 76mm diameter piping is key to its performance gains, especially for engines that have seen significant upgrades or forced induction. This setup is designed for maximum flow, featuring oversized tubing and mufflers that contribute to a notably louder and more aggressive exhaust tone compared to other MegaPower systems. The system includes a resonator for some sound control, stainless steel flanges, and a straight-through racing muffler with a 4-inch polished tip that sports an acid-etched MegaPower badge and a serialized nameplate.

Installation is straightforward as this is a bolt-on system designed to work with the factory exhaust mounting points, meaning no welding or fabrication is required. A removable silencer is included if you need to quiet things down a bit, along with all the necessary hardware for installation. This system is based on the same designs Skunk2 uses for their own road racing and time attack vehicles, offering a well-built option with a distinct sound and improved performance.
