1)I have some Magen Headers on my evo 8 and i got it tune but don't like them any more and was think about getting my stock headers port and polish. Will that throw off my tune?????


2)I called some shops around and they told me not to do it because it will make them to thin from the inside and they mabe crack on me............it that true??? i dont i would like some one's in-put

might throw it off just a slight bit... but it anit anything that your "definately" gonna feel a difference. i would just throw it on the dyno when you change it out and get 2-3 pulls on it to check to see if everythings fine.

Obviously if your car is tuned for one set of mods and you change something the tune will no longer be optimal, but it shouldnt be dangerous if that is what you're asking.

true... they are more prone to cracking once they have been ported out. But i havent heard any problems or seen any yet. (i had problems with my turbo integra, but that was due to the heat wrap that was on the manifold) Bushur makes a pretty reliable manifold. Call them up and ask them the same question u asking here O0

1). yes it will throw off your tune because they are tunned to the megan headers.

2). stop talking to the shop you called for the port and polish question. they dont know what they are talking about. if you like go back to the stock manifold and get it ported and polished. i got mine done at buschur racing. i luved it!!

i don't usually condone buschur parts, but their port/ polished header works. i had the dc sports and did not see a significant gain with the header. imo, save up for a different mod.

purchasing an aftermarket ex mani... not much of a difference and a PITA to install... so many different things can go wrong ... making an easy task a nightmare...
