Premium Construction & Installation Info
The PPE High-Flow Exhaust Manifolds with Up-Pipes were constructed using only premium materials to ensure maximum strength and long-lasting functionality. The manifolds and up-pipes were crafted from stainless steel, 11-gauge, .120-Inch Wall tubing that is strong enough to handle even the most aggressive driving applications, ensuring your truck will make it home in one piece after each one of your adventures. The manifold even comes standard with a pre-drilled and tapered 1/8" NPT for an EGT gauge to make sure your exhaust temps are under control. Additionally, the up-pipes have a increased inner diameter over stock to improve flow without compromise. When it comes to installation, this exhaust kit can be mounted directly in place of your existing components for a fast and easy process you can complete at home.
