Straight Pipe Exhaust Upgrade Makes Your Presence Known

Transform your 2004.5–2005 GM 6.6L Duramax with the Diamond Eye 4-inch Aluminized Cat-Back Single Exit Straight Pipe No Tip Exhaust. Designed for drivers who want bold performance and an aggressive exhaust tone, this system eliminates restrictions, enhances efficiency, and delivers a raw, unfiltered sound each time you set off for adventure. The straight pipe configuration removes the muffler entirely, allowing exhaust gases to flow freely. This design produces an unfiltered exhaust note that amplifies the power of your 6.6L Duramax, making your presence unmistakable on the road. If you decide to soften the tone later, the system is versatile enough to accommodate a muffler by simply replacing the eliminator pipe. And to make things easy, this system bolts directly in place of your truck's factory exhaust to make for a simple and straightforward process you can complete at home.

Aluminized Steel Construction & No Tip Design

Built from premium aluminized steel, this exhaust system resists both rust and corrosion, making it durable enough for rough driving and harsh environments. What's more, the 4-inch mandrel-bent tubing maintains smooth, unrestricted flow, reducing backpressure and improving overall engine performance. These improvements lead to slight gains in horsepower and torque, better throttle response, and increased fuel economy. Additionally, the system lowers exhaust gas temperatures (EGTs), protecting your engine during high-performance applications such as towing or off-roading. It's also important to note that this particular system does not come standard with a tip. This allows you to leave the exhaust bare for a more rugged look, or add on an aftermarket tip of your choice that matches your personal style.
