So what shoudl I expect from this set up. This is my first mod and I was wondering how much of a difference will I feel over my stock set up.

 

you'll hear more of a difference than feel, that's my opinion. i had the same setup originally and the injen makes the car sound meaner but as far as performance, it was unoticable...don't get me wrong, i'm sure it does increase power but it's minimal. now, when i installed my japtrix y pipe and midpipe's then you could hear and feel the difference in the car have fun w/the install and enjoy
