Thread: GTP vs GTX

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

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?

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

they had headers and a 3.5 or 3.4 too

Limited Editions

the ram air hood adds a whopping 5hp

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.

^^x2 They had 3 stages.

theres a stage 3 in hemmings

15k for 1200miles.

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.

and are RARE

SLP Pontiac Grand Prix

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

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