Overall Assessment

Customers believe that the product excels in terms of its fit and compatibility with various chassis, especially custom ones where other similar products failed. They acknowledge that some tweaking might be required to achieve optimal fit, such as repositioning O2 bungs and tolerating minor interference with the frame. The finish, advertised as "black ceramic", seems more akin to high-temp paint, indicating good quality. Users appreciate the additional space for plug wires, however, they suggest improvements in the flange material. Despite minor setbacks, customers ultimately recommend it for its superior fitting ability.

Fit my custom chassis with minimal mod to car body mount where other headers wouldn't clear frame or engine mounts. O2 bungs not in correct position, will need to plug and a new one further downstream. Finish advertised as "black ceramic" but more similar to high-temp paint. Room for plug wires, flange could use thicker material. All in all, thankful it fits and hope it works.

Great product but not for my app.

Bought for ls3 conversion in a 1951 chevy pickup , would have fit if not the the collector flanges hit the frame , could have cut them off and re positioned so bolt hole ear would clear but had different headers that were a better fit .
