Overall Assessment

Customers highly praise the product for its perfect fit, quality, and practicality, stating it effectively eliminates exhaust leaks. Its material quality is often highlighted, with heavy gauge steel providing durability and longevity. The product's versatility shone through as it was usable in tight spaces and accommodated various pipe sizes. Several users recommended this as an affordable and high-quality alternative to others on the market. Despite some suggesting longer bolts for improved usability, the product's overall performance and fit received widespread commendation.

Solid Product!

I bought these header collectors for an LS swap project that was missing O2 sensors. These collectors have a solid build and come with a protective exterior coating to eliminate rust. I welded on some O2 bung that allowed me to connect these to my existing header and my swap. For the price, I highly recommend this kit. It comes with the collector, nuts and bolts and gaskets for easy installation..

Works, however

Good quality and finish. However supplied bolts (one inch thread) are not long enough to attach 910-0329 ram horns. Not enough length to attach lock washer or nut. Need to purchase longer bolts.

I was building a race truck and needed collector for the headers. Couldn't get them from auto zone or O'reilly's even tried Amazon. Speedway had what I needed.
