GTP vs GTX

[tdm571]

Were there any mechanical differences between the GTP and the GTX? Or were they all just for show?

[tcman49]

factory 17 inch GTX specific chrome rims, ram air hood package, GTX badging, 10hp increase to 250. Just a package pretty much.

[Dtrick22]

Well, I don't really know if it would add any noticeable power like they claim it does, but the Ram Air hood may help it a little bit....I'm not totally sure what they did with the exhaust, I know it had SLP mufflers but did they go all the way and put SLP headers on it from the factory?

[RamonGTX]

There's no difference other than cosmetic and yes they claimed the exhaust and ram air made a huge difference. If you went through my car and a stock gtp id be the same except appearances and exhaust

[z3r0]

they had headers and a 3.5 or 3.4 too

Limited Editions

the ram air hood adds a whopping 5hp

[Bio248]

the ram air hood adds no horsepower.

if you were EXCESSIVELY LUCKY you got ahold of a stage 3 gtx that came with 1.8:1 roller rockers and a 3.5 pulley. the rest of everything is cosmetic and absolutely useless as far as performance goes.

[redlinepontiac]

15k for 1200miles.

I heard the stage 3 cars were a myth and no GTP/GTX ever came with different rockers.

[rynoman03]

Well your mistaken.

You "heard" wrong...SLP Stage 3 cars came from the SLP department with a...

Ram Air Intake System, Press-On 3.5", Mag. 1.80:1 Roller Rockers, Catback, and a PCM Tune.

[redlinepontiac]

and are RARE

[SnowFlake]

So these stage 3 cars with rockers were offered all 7 years?

SLP Pontiac Grand Prix

i almost had to click my mouse 3 times

I'm pretty sure that it was only offered at the tail end of production (just like the regal gsx stage 3)

[redlinepontiac]

it said end of 03, should i bother digging up dealer brochures for that year?
