Poll: catback systems & gas mileage

[Liquid Silver]

Hey this is a question for anyone who has upgraded their exhaust to a catback system (any brand). All I want to know is... did you experience better gas mileage after the catback was put in?

ofcourse, you get from point A to point B alot quicker with an aftermarket exhaust :D

you will not get a true answer because of the fact that when you hear your car growl the first time you will be wot alot more [img]graemlins/burnout.gif[/img] [img]graemlins/rofl.gif[/img]

I haven't seen any isgnificant difference at all, but my mileage is getting high too, so both could cancel each other out

Here is an equation that was figured out by a wise man many many moons ago

Any mod that improves gas mileage...

Add gas mileage + Added foot poundage to accelerator = no change in gas mileage but you get there louder and faster and thats all that matters.

I have take 1 interstae trip like 200 miles each way and got READY FOR THIS 35 mpg !!!! i have SLP CAI and 2.5" back from the cat.
