I want to put on a Long tube header and a 2.25" flex pipe to my focus i already have a 2.25" borla exhaust and a cai. can expect to see a noticeable difference?
Borla's exhaust is 2.5". I went from stock to full header back exhaust on mine and I noticed a huge difference. I think you'll notice a difference as well because of how restrictive the stock header is. You'll also notice a difference in sound
It will be small gains but what you will notice most is tq loss. I thought I lost power when I put the header on but when I ran against my friend I gained a fender.
i didn't know how much i would gain by spending 500+ on the header and flex. I thought of putting on a Supercharger (I know they don't put out the HP turbos do) will a automatic hold that kind of HP?
You can get parts for your trans to beef it up from a company called Lentech. I think i spelled that right. I think I've read that the autos will hold like 225hp or something in that range from factory.
