Have any of you noticed a increase in MPG with your CAI and catback? I'm looking for ways to increase our MPG and in the past with my other vehicles I know that this was a great way to do so.(and to gain a few extra HP )

 

all I have is a catback and mpg is the same but it feels quicker. saving up for a CAI though.

 

I have i/h/tpipe/cat-back and to be honest the gas mileage seems to be about the same. I get roughly 310-350 to a tank driving highway/town...it hasnt changed...

 

Intake & axle-back exhaust here.
No increase in MPG, horsepower gains are minimal at best.

 

i've got H/I/E. mpg seems to be slightly better. i used to get roughly 27.5-29, but now i'm getting more towards 29-30. again, this is when i'm driving economically.

mostly city driving. i live in b'ham, AL, and there are a TON of friggin hills and valleys.

 

I have intake, and exhaust, and no change really?

 

well, with my axle-bach i didn't really see any changes...BUT when i installed the K&n drop in filter, yeah i did notice a difference. THEN i went w/ a last station powerbox and DEFINITELY see improvements. Once i install the headers, i'll keep track of what's goin on and get back 2 ya.
