The part itself was simple and installed without any trouble.
The components are clearly high quality. Pipes, hardware, and gaskets are well made. Install pending, but first impressions are excellent.
If you’re deleting your truck, this upgrade is absolutely worth it. It eliminates the weak points of the factory up-pipe design and removes the EGR split entirely. For long-term reliability, this is a smart investment.
Perfect fitment. No issues during installation.
Build quality is excellent, though the fit is very tight. The baffles make contact with the head and create an unpleasant rattle.
