If i get true dual 2.5 inch exhaust, megan headers, and and injen cold air intake kit....how much power would that really give? would be noticable and a little bit more fun to drive? i have and 05 coupe automatic

 

it would be louder. louder = faster

it wouldnt give any more power to make a difference.

 

It'll give you sound, but not much power.

Do you have a spacer?

 

stock intake is well sealed from engine heat. notice how stillen uses the exact same design as stock just different filter? cold air is bogus on these cars. Headers=waste of money IMO. $500/labor=1-2 HP gain....get the spacer if anything, exhaust only for sound or weight loss. If you want to have fun track the car in a safe enviroment. hope this helps.

 

you should get a little more power...however i would recommend after putting all those bolt ons to purchase a cobb access port to get the full potential from those mods

 

Intake doesn't do much to our car.
and if you are planning to get headers get something more decent.
Not some MIC crap.
