Modified OEM Downpipe

This is an OEM downpipe that has been modified at the exit to fit a different mid-pipe or custom exhaust setup. The original flange is intact, and a slip-fit extension has been welded on for aftermarket adaptability. Ideal for budget-minded builders or fabricators looking to work with OEM geometry while tailoring their own exhaust routing.

✅ OEM GM Downpipe Core – Fits stock turbo flange
✅ Custom Welded Extension – Allows for non-factory hookup
✅ Structural Integrity – weldable hole
✅ Perfect for Custom Exhaust Builds
