Overall Assessment

Customers appreciate the product for its perfect fit and easy installation, particularly praising the improved accessibility of the bolts compared to previous models. The headers reportedly work well in sportmod applications. However, some users encountered issues with the durability of the tubes, expressing concerns over cracking and melting after limited use. Despite these problems, there is a clear preference for our product over competitors due to its compatibility and straightforward setup.

Bought these in 2021, installed on the car in the middle of the season, and didn't race since the driver had to have surgery. Headers only had garage time. After the first night this year, a couple of tubes were cracked by the mounting flange. Every week, a different tube is cracked on each side. One tube even melted through one night.

I ordered these headers to replace the bent driver side header on my Allen modified. I wasn't sure if these would fit my chassis but I ordered them any way. When they arrived I put them on and it was a perfect fit. The bolts for these headers are a lot easier to get to than my previous headers, which made the install a breeze.
