I have an FP red on my car, with an open air filter attached to the MAF.

I need to know if i will see any gains by going to a hard pipe. I was about to make the jump, but i've read that the hard pipes cause a lot of problem concerning stalling issues and similar, and that it takes a lot of work to scale it, and that even after scaling, it's never spot on.

if you can give me different opinons wether i really need an intake hard pipe, and if so, which pipe would be better concerning performance, as well as relatively easy to scale.

Thank you.
