i didnt know borla made a 2.25"? is it a trubendz?

anyways, you would def. feel a difference, not 20whp or anything but you would def. get some gains IMHO.

I was thinking it was a 2.25 but I'm more then likely wrong... it's been a while since i installed it

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.
