Has anyone installed the FSwerks Stealth exhaust system with the cold air intake on there 2008-2011 Focus? If so, did you notice any difference in power/pickup and or gas millage difference?
You will be hooked after them two mods yes better power and gas milage. You just wont see the mileage because your going to love the sound of the car in upper rpm range.
This exactly! People complain that they saw no Mpg improvements from cai, exhaust, tune, etc. but its due to them now driving more spirited. I assure you if you can control yourself you will see improvements in mpgs. its common sense. better efficiency yields better performance or better mpgs. Those who say it won't are idiots lol
You will not notice anything drastic in better mpg, if that's what you are asking. The cost of an intake/exhaust will probably not be realized in mpg gains or anything. You will realize that your car sounds much better and has an increase in power, that is worth the price of admission imo.
Thanks guys for all your answers. I did put the intake and exhaust on and i do notice a bit more power. One thing i notice about my car is the transmission seems to have a lag/slow response on the down shifting, but other than that it does sound nice. But now i'm interested in this header that i can get for the car. I bet from what i've seen in this car it's not easy to install. I'd like to know where i can buy one. I guess i'll look on ebay.
Fwerk's, CFM= central florida motorsports. And yeah you'll find the obx on e-bay. You'll find a tune w/ really help also. For your trans. shifting & better drivabiltiy. Have them turn off the egr & rear o2 senser.
Honestly and anyone can disagree the biggest pain was actually getting the stock manifold and the heat shield etc. out of the vehicle. Putting them on was a breeze. Thats just for 08-11. I could imagine 03-07 isnt to different.
Hello everyone! Ob1juan here as a noob, and I must say that, I know will be the hardest thing to do! With just the SRI from Steeda I already feel a difference and it is a beautiful sound! But to hear it I must "kick-it"
imo, if your going to do them 2 mods get at least ONE more.. a tune.. 91 Octane and add another but of HP at the same time your going to milk them to mods just a bit more..
