    Grimmspeed is the best. A lot of people recommend it.

    I personally have a Perrin model. Has lasted for many thousands of miles. No complaints.

    With no pre-cat you really do not need one.

    Why bother? You don't have a pre-turbo cat

    Unless you are really trying to squeeze every little bit of HP from your car, the uppipe won't do a lot on its own - and it's a bit of a pain to install unless you already have the downpipe off.

    I have the perrin uppipe and headers, and together they made a nice boost, but solo, looking about the OEM uppipe and the Perrin one, I doubt there would be more than a few HP gained from the switch.
