Recent Customer Feedback:
My name is Chris Giuliano I purchased a AFD manifold for my xd 383 stroker and I am so happy with it. I would just like to let you know that I had a wiend excellorator manifold on it before and had it dynoed at 272hp at the tyres. A bit unhappy for the money I spent on the engine. But was told about the AFD manifold, I did some research on manifolds and found that I would give your one a go. After I purchase it and put it on my car I found the drive ability great and power fantastic. I recently put it on the dyno un-tuned from before except changing the jets in the carby and it gained 70 hp at the tyres it made 341hp at the tyres, Cant wait to get it tuned should still get a little more out of it.

Thanks for your time as once again just thought I would let you know you have a great product.

Chris Giuliano.
