Which is best??
Guys i have the kleeman K2 on My car and i got 420whp which i think is low compared to other cars that have it, maybe its because of the hot weather we have here i dun really know, anyways im thinking of taking out the shorty headers, and putting either MHP Long tubes or Evo sport Long Tubes which of these 2 u guys recommend best to gain the most possible whp out of my car!??

I believe that the gains from both companies will be about the same. So to me it comes down to credibility and with the recent events that have been happening to MHP on mbworld I would say go with evosport. If you would like more details I believe hhughes is running k1 and mhp longtubes and dad c63 is running all mhp while c63 guy is running all evosport. I think pming them would give you better insight on the company and their products.

Long tube headers will have an enormous impact on power output, nearly as much as a stand alone tune. And hot weather will rob power for sure although humidity may be a bigger culprit. My K2 pulled 430's in cold dry weather and ~415 in summer. The MHP long tubes raised whp by 44 and tq by 32 same dyno/conditions(95degrees50%Hum). Keith and I do go to the track(s) together but the season has not started here yet. His car has several additional mods(ported heads,airbox,light wheels,rotors etc) beyond tune and LT's but I am certain that the MHP tune is stronger than the Kleemann by design. With some 40 degree temps and a decently prepped track we should both see significantly better performance than our current sig numbers state. Keith may blow away any non N02 63 number at MIR next month.
