REACHING OUT --has anyone heard of or used headers from DNA MOTORING? I would like to put an exhaust on my 2014 F150 STX 5.0L. I'm thinking of starting with these headers from DNA part # HDS-F15011-50L keeping my factory cats and finishing it off with a CAT BACK FLOWMASTER AMERICAN THUNDER . These headers are 200.00 buck online. I hate to order them just to be disappointed or am I being to hesitant on a good thing. any feed back would be helpful. I also plan on a FLOWMASTER COLD AIR INTAKE- DELTA FORCE to finish the job. Thanks for reading
