It's probably already been discussed, but I have a question regarding headers.
Has anyone used Flowtech headers on an FE?
What kind of quality did you find with them? How about fit?
I'm not asking about performance gains over stock manifolds, because I've made up my mind that I want to put headers on the 390 I'll be building.
But, how do they compare to other brands of headers as far as performance.
Opinions???
