    There was a big ULH comparison thread on nasioc.. I wouldn't worry about it unless you're running a larger than VF turbo. From what I remember, they all spooled slower than stock, some were near equal to stock in top end, and some had decent gains from 5000rpm up. But if you're stage two and are looking for more power turbo upgrade will be the best bang for your buck.

    I know a few people who went from UL to EL headers. Some were the same brand and had the same tube diameters. Not one of them wanted to go back, not even the ones that had been fans of the blub-blub sound. A header is a performance modification. Last time I checked, UL were not any cheaper, or longer-lasting than EL headers. If you're more interested in sound than performance, just keep the stock manifolds.
    Happiness isn't just around the corner, it is the corner.

    I agree. I should have clarified.. only meant that the STI is simply a better platform for those that want to mod furiously.

    As you said, on the street there is not much difference between the WRX and STI. That's why I chose to save money and buy a WRX for my daily.
