“I was very impressed with the quality and materials used in the construction of the downpipe and front pipe from PRL. You can tell that PRL put a lot of time and thought into developing them. When comparing the downpipe and front pipe to the stock ones, you can see where they've removed the restrictions via increased diameter openings and overall pipe size. I was hesitant to order the front pipe, but that's probably the biggest restriction improvement, so I highly recommend getting both. I like the stealthy look, so mine are paired with the factory exhaust and muffler. Unless you open the hood, it's invisible to the world. Sound is just a hair more aggressive than stock and fits like a glove. Please note that it comes with no installation instructions whatsoever, but there are several helpful videos on YouTube.”
