A properly designed exhaust system is critical to engine performance. Skunk2's 76mm MegaPower RR Exhaust system for the 2012 Civic Si coupe 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 RR systems are constructed of T-304 stainless steel, are robotically TIG welded, and feature CNC mandrel bends for a precise fit. The MegaPower RR for the 2012 Civic Si in conjunction with the Skunk2 Alpha Header for the 2012 Civic Si has seen hp gains above 30hp. Designed for heavily modified naturally aspirated engines as well as for turbocharged applications that require more exhaust flow than Skunk2's 70mm MegaPower R Exhausts provide, MegaPower RR Exhausts allow engines to breathe more efficiently and produce more power thanks to larger diameter piping. MegaPower RR Exhaust systems were designed for maximum flow and power, featuring oversized tubing and mufflers, which result in a significantly louder tone when compared to other MegaPower systems. Featuring Japanese-spec, Super N1 styling, MegaPower RR 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 systems are based off of the same systems we custom build for our road racing and time attack vehicles.This Part Fits:

Comfortable durable undershirts that keep up with active kids
Special Size: T Shirt, Size: Small, Color: T Shirt - Boys - 10 Pack - White, Special Size: T Shirt, Size: Small, Color: T Shirt - Boys - 10 Pack - White
These Fruit of the Loom boys undershirts have been a great everyday essential in our home. The cotton fabric feels soft right out of the package and holds up really well after multiple washes without losing shape or becoming rough. That is a big plus when you are constantly doing laundry for kids.
What really stands out is how practical they are for active days. The moisture wicking feature actually helps keep my child feeling dry, even during school and playtime. The extended hem is another thoughtful detail because it truly stays tucked in and avoids that constant adjusting throughout the day.
I also appreciate the tag free design and layflat collar. There is no itching or irritation, which makes a noticeable difference especially for kids who are sensitive to textures. The fit is flexible and comfortable, making them perfect for layering under school clothes or wearing on their own in warmer weather.
Overall these undershirts strike a great balance between comfort, durability, and functionality. They are reliable basics that make daily routines easier and more comfortable for kids.

Pack of 7 t-shirts for an unbeatable price cant beat it
Special Size: T Shirt, Size: Medium, Color: T Shirt - Boys - 7 Pack - White
When I saw the price for the amount it brought I was instantly sold. White t-shirts are always needed but the price for 7 of them cant beat it. Only reason I gave it 4 stars is because I got my 11 year old son a medium which is the size he usually wears and they are super snug he wore them already and I washed them and they are a bit tight to wear out but to be inside the house its fine. Im ordering more and getting a Large this time. Will write a review once I receive the Large to advise if a bigger size is better just incase anyone is buying for their child around the same age. The quality of the shirt is great as well not to thick but not to thin just right and my son is picky with the material of clothes and he loved them.
