exhaust mod 1st for most power or does it matter.

Mark Gomez

I have a question in regards to the the "1st mod performed" and how much horsepower versus the 2nd and 3rd mod. From what i have been reading from other forum members is that the 1st mod yields the most power and less on the next mod. Well i will be installing the Fast Intentions exhaust and K&N drop ins with the hps tubes, and i was going to install everything at the same time, Now what? Do i do the exhaust 1st and drive for awhile to get the most horsepower and wait to install the tubes and K&N? Cause they produce the least power gain. Or does it matter to install all at the same time? Confusing to me. I use to own an EVO 8 and it didnt matter what mod i installed 1st or 2nd i still got the horsepower it should produce not less cause it was a 2nd or 3rd mod. Please help me answer this question before i start installing these parts.
