AP Exhaust 28688 Bypass Pipe (BPF Delete) for Subaru Impreza WRX STI (2004-2007)

The AP Exhaust Bypass Pipe 28688, also known as a BPF (Bypass Filter) delete pipe, is a high-performance exhaust component designed specifically for the Subaru Impreza WRX STI model years 2004 to 2007. This pipe is an excellent modification for those seeking to enhance the power output and exhaust note of their vehicle.

The AP Exhaust Bypass Pipe 28688 is a direct replacement for the factory catalytic converter and catalytic converter bypass pipe. By removing the catalytic converter and associated restrictions, this pipe allows for improved exhaust flow, which translates to increased power and torque across the entire RPM range.

Constructed from premium 304 stainless steel, this AP Exhaust component is both strong and resilient. The material's superior heat resistance ensures that it can withstand the extreme temperatures generated by a high-performance exhaust system without the risk of warping, melting, or failing prematurely.

The pipe features a polished finish, adding an aesthetically appealing touch to the underbody of your WRX STI. The smooth, mirror-like surface is not only visually pleasing but also resistant to corrosion and oxidation, ensuring the pipe retains its appearance for years to come.

Installing the AP Exhaust 28688 Bypass Pipe is a relatively straightforward process, requiring only basic hand tools and a few hours of your time. The pipe is designed to fit securely and perfectly align with the factory mounting points, ensuring a clean and factory-like installation.

By eliminating the catalytic converter and its associated restrictions, the AP Exhaust 28688 Bypass Pipe allows your WRX STI's exhaust gases to flow more freely. This results in a more aggressive and pleasing exhaust note, which is a welcomed addition for many Subaru enthusiasts.

In summary, the AP Exhaust 28688 Bypass Pipe is a high-quality, performance-enhancing component for the Subaru Impreza WRX STI (2004-2007). This exhaust modification delivers increased power, improved exhaust flow, and a more appealing exhaust note, all while boasting superior durability and a polished finish.

Buying a BPF (Back-Pressure Free Flow) catalytic converter replacement exhaust pipe (AP part number 28688) for your vehicle can offer several benefits and potential drawbacks. Here are some key considerations:

1. Increased Performance: A BPF exhaust pipe allows for better exhaust flow, resulting in increased engine performance and power output.

2. Improved Engine Sound: The freer exhaust flow can also lead to a more pleasant exhaust note or "exhaust tone," depending on personal preference.

3. Better Fuel Economy: By reducing back pressure in the exhaust system, a BPF exhaust pipe can potentially improve fuel efficiency.

1. Higher Cost: A BPF exhaust pipe like the AP 28688 is generally more expensive than a standard OEM exhaust pipe due to its performance-enhancing features.

2. Potential Increase in Emissions: As the BPF exhaust pipe allows for more exhaust gases to exit the engine faster, it may lead to increased emissions, potentially affecting vehicle emissions compliance.

3. Potential Impact on Catalytic Converter Longevity: Since the BPF exhaust pipe allows for faster exhaust gas flow, it could potentially put more stress on the catalytic converter, potentially reducing its lifespan.

A BPF exhaust pipe like the AP 28688 can offer noticeable performance improvements, including increased power output, improved engine sound, and potentially better fuel economy. However, it comes with a higher cost, the potential for increased emissions, and potential impact on catalytic converter longevity.

If you're looking to enhance your vehicle's performance, a BPF exhaust pipe like the AP 28688 could be a worthwhile investment, particularly if you're also interested in improving the engine sound. However, consider the potential costs and potential drawbacks before making the purchase. It's also essential to ensure that any modifications made to your vehicle, including installing a BPF exhaust pipe, are compliant with local emissions regulations.
