·Hi all. I apologize if this question/topic has been flogged to death before. From what other people have told me and from various posts on these and other boards, I'd come to expect that installing a free-breathing air filter/intake and a high-end exhaust system on an Evo 5/6 would provide between 20-30 additional HP over stock. This assumes no other mods, and leaving the boost alone.
However, I was told by a local high-performance tuning/race-prep shop that just slapping on an intake and exahust will only net an increase of about 5-10 HP. They sell many of these products themselves, and their comments are based on their own experiences setting up various Evos. The shop has a rolling road and have prepped Mitsu Evo's, Eclipses and even Honda Civics to well over 500HP (dyno-tested), so they seem to know what they're talking about.
What are people's experiences with filter/exhaust upgrades? I was keen on investing in these (for my as-yet completely stock Evo5,) but if performance gains are marginal (i.e., 5-10HP) then I may think twice. Thoughts please?
Thanks, and cheers!
