Just a post to say that I installed the CNC Fab HPOP lines with crossover on my 260,000 mile truck. I was worried about the long crank times for the first day, and emailed Corey about it. I can't say enough good things about the level of customer service he gives.
I got all the lines installed without having to remove any other components on the engine, and the motor sounds quieter and smoother than ever.
More than anything, though, the customer service is stellar. He sells a top notch product, and stands behind his work. Thanks again, CNC fabrication.
