the step tube header that I will be building for the 420a, will definately produce a strong mid range pull, the step tube header by design gives you the best of both worlds, it gives you a very broad tq curve, with an awesome top end charge, this header should pull strong from 2500rpm all the way to red line thanx Jason

if yours proves better than my hotshots 4-1 i have on my car now.. i will definately want one :thumbsup
