How much hp gain would we get if we installed all three of these in the xb. Would there be a dramatic or slight difference in power? How much would it ruin the mileage? And is it worth it? Im thinking about getting the dc sport header, K&N typhoon intake, and borla exhaust and was wondering how much of a change it would be then stock. I drive an auto xb.

 

which borla exhaust? the axle back or the dual exhaust? And are you looking for the most power? Or are you on a budget? Also couldn't you just add together the HP gains from all the companies?

 

The only way intakes and exhaust hurt mileage is because the extra HP makes it more fun to put your foot into it more often=less mileage. If you keep your foot out of the throttle you will get better mileage.

From those parts-maybe 10 or 12 hp, you will notice it but it won't be huge. If you do a header back exhaust you will gain a little more.
