Increasing HP on 2004 Max with Air & Exhaust

How much extra HP can I expect to get in my 2004 SE 3.5l by adding an air
intake system and a Cat-back dual high performance exhaust? I heard 50. Is
this true?

Usually normally aspirated performance enhancements (intake, exhaust,

UDP etc) tend to increase a car's HP by 15%. So your Maxima's HP will
probably increase from 265 HP to 265 * 1.15 = 304.75 HP, a 39 HP increase.

Of course the noise will increase, too. Be prepared to live with it.

IMHO that's on the high end of what you get from cars that already have
"high performance" engines like these do. I'd be shocked if you ended up
with even 10% HP increase from these mods and sometimes these types of mods
LOSE power, they just make more noise! Even 40HP from an air intake and
exhaust isn't going to happen on one of these cars.

Not to mention the risk of voiding your warrantee, and not being able
to pass local emmision tests.
