    I would not even know...I just got this car, I have a 95 TA that I spend most of my time and money on and I am very familiar with her, but the GTX is a little foreign to me as I never had a supercharged car...I know engines are engines and intakes, headers, all that does the same thing but the pulley, downpipe all that, ubend thing is all new too me

    As far as the intake...it has a fuction ram air...I looked at it and it is not true as I would have hoped...it has to travel over to the air box through a little hole from the side of the hood, it says it add 5 hp over a standard GTP, but who knows...and U-bend delete...What is that?

    Look under the car at the exhaust in the general area of the front seats. You'll see what the u-bend is.

    there is no such thing as "functional ram air" on our car. make a good intake and ditch the air box that it comes with. even with the air flowing from the hood, you wont get any sort of power out of it.

    Yeah those things are EPIC FAIL lol

    The GTX only came with the 3.5" if ordered with just like the SLP Tune, SLP 1.8 Roller Rockers, SLP Catback...

    Other than that all it had was badges, wheels, SLP Hood, and SLP Intake...

    I just called them, they didnt make a certain amount and they didnt keep any records, basically anybody could have took a GP and made it a GTX, even if it was a GT...so they would not know. I guess I could measure the diameter of the pully LOL!

    Well...they did conversions on North Carolina I think...you might try finding out what places did what in GM for the Conversions... Not sure...

    If you do have a 3.5" then I would say spring for some exhaust mods and let that thing breathe
