Planning on getting a gxp and need some info. Hey guys, like the title.say I want to get a gxp. I plan on modding it but, not go to crazy. What mods would I need to run 13.5-13.8? I was thinking a tune, cai, and headers or cat-back. Will that get me to where I want to be? Also can you guys recommend a good tune to get and a good cai and good headers and where I can purchase these. Thank you in advance guys!
Buy my 08 GXP. LOL
13.72 @ almost 100mph on Rikken Raptors...and those tires BLOW...
3" Hogan Catless DP w/3" exit flange
Single 3" into Dual 3" catback
Custom Fabbed CAI
is all it took to get there...
If you don't wanna buy mine (can't blame me for the shameless plug...haha) almost any GXP/ISS/MCSS in decent shape should be able to get into the 13's with a good exhaust, intake, and a DiabLew Tune and not much else.

Why? Many people have gone 100k+ miles on stock transmissions with a trans cooler and a good tune. They are a weak link, but shouldn't scare someone away from buying a car if you know how to maintain your vehicle.
^^^^this. Hell even with my mods my car is still shifting like it should. A couple of mods like a shift kit cooler and tune go a long way in the name of longevity.

The transmission problems are certainly NOT an isolated issue...but are FAR from an epidemic...
Proper care and maintenance will sometimes make it last and sometimes you get the **** end of the stick...as with any vehicle...but go in knowing that it COULD happen...
the upside is Dave @ TEP is pretty much the Einstein of 4T65-E HD's and can build you something that odds are you'll break your entire family's wallet before you break the transmission again...

Thanks to the input on here before I bought my car I bought a warranty and just had the transmission replaced at 50k covered under it. Don't be afraid of buying the car but either put the money aside or buy a comprehensive warranty. I don't know where you live but good snow tires make a world of a difference in the winter too before you go modding.
I don't know about that. My TEP cost me roughly $4.5k and Dave said 400whp was the max for it. But yeah, I ran a stock transmission on 350whp for about half a year before upgrading and the transmission was as strong as when I bought her stock. So these transmissions can take a beating.

For a DD yes. For a "Sometimes" track car more than likely.
Until you decide to try to catch traction. and can't. on the off chance you do there is still a high probability of chain damage & disintegration. Dave also recommends inspection/replacement as a regular wear maintenance item once modified on a high horsepower application...
Not defending or playing against the GXP, TEP, Camaro, or anyone/anything else...but I feel a lot more comfortable about my odds of making 460whp last in the camaro than i do in a GXP...
The GXP/MCSS/ISS make wonderful sporty daily drivers...some here have made them exceptionally fast...and hats off...
but to me it's about being payment free right now and i can go a lot faster for ~8k in a Z28 than i can for ~303 a month plus 8k cash in a GXP.
