The new Twisted Steel performance header from aFe Power is redefining the header industry with new pulse control technology. aFe engineers have designed this header using optimum tube lengths and mitered collectors for maximum flow and velocity for power delivery across the entire power band. Combine with a large 1/2" thick head flange and 14-gauge 409 stainless steel tubing, you have a header that is strong and powerful. Twisted Steel headers are 100-percent bolt-on with no modifications necessary and are proudly engineered and built in Corona, CA.
