2004 Grand Prix GTP Magnaflow XL Turbos

[CNrite]

i took a ride in a grand prix gtp today it had shit loads of mods went door to door with a cts V....oh yeah and the grand prix had 450 hp to the front wheels lmfao

[MrRedMan61]

Sexy I have the Same one And want mangnaflows soo bad

[nighttrain334]

Sound like a oldsmobile cierra ;^D Really it do! UUUGH

[Ryandsullivan23]

how much did it cost to put those on

[Joose]

@Ryandsullivan23 Couple hundred probably, but that will vary between shops I'm sure.

[BogerD17]

That sounds good! Did you have the resonator removed? Ive got dual thrush super turbos on mine and they are much quiter. I miss my old "no muffler" setup lol. Good vid!

[Joose]

Thanks man. Resonator was still in at the time of the video. I removed it later though.

[knaxon]

@BogerD17 Word I ran one of those set ups. I still have the videos from 04 GT with straight pipes! i drove like that for months.

[Joose]

Don't know the part number, guys. Sorry. I don't have the GTP anymore so I can't really check either. The place I got them just said they were Magnaflow XL Turbos.

[killerwhale187]

I have a 2004 GTP, Mine's White. I've got Magnaflows. But don't sound anything like what you have there. Did you change pipe sizing or anything like that?

[Joose]

Nope, didn't change a thing.

[JQUiK84]

mine is a gt2 n it sounds like that but get flowmasters if you want more loudness magnaflows is for horsepower

[Joose]

Every Grand Prix I've heard with Flowmasters sounds like a rice burner. I don't suggest Flowmasters to anyone. Just take off your resonator.

[JQUiK84]

i put magnaflows on mine

[Roflcopterv1]

Yeah unfortunately flowmasters make most American v6's sound like rice. And thanks for the tip. Im planning of getting a GTP as my first car.

[ImgonnasayNO]

I'm with that last comment, apparently my mufflers are shot at 45K so it's time to upgrade. Let us know what you used...

[dackms2001]

what is the part number on these mufflers?? And whaich exactly are they? I have a 2005 GP GT im putting them on.

thanks

[kwhooligan]

yes they have an after market PCM for '04s, it look and fits the exact same as stock bro! great when installed cams and rockers and shit like that to reset for retarded knock of gained boost

[fortstockton]

does anyone kno if theres a chip for the 2004 grand prixs???

[CBRage1000rr]

a Chip ? dam you dont know about cars at all .. lol a chip.

[footballplaya3k]

You Don't get a chip, you get a tuned PCM or a tuner to do it yourself

[KatsukiLennox]

Oh wow, these sound great! Now I think I know what to get for my Grand Prix LOL

[GTavalanche2rider]

if anyone knows where i can get a beefy transmission for a gm4t65e please message me. my turbo volvo uses the same tranny as grandprix, and it cant handle the shift loads after i put a chip and mass air in!

[mattmopar440]

get the hd tranny from a gtp and put it in there, i beleave its a th460e-hd

[ajl227]

Sounds good!

[bighurt130]

dont remove the res or it will just sound even more raspy,you dont really need bigger exhaust until your runnin alot more hp,get a K-N CAI,irridium plugs with per. wires,and go for a custom overkill PCM,then your carwill really wake up,plus a zzperformance dowpipe

[Joose]

I did remove the res, just for the fuck of it. Didn't make much of a difference really. Already have a CAI, Wizaired with K&N Filter. Better than K&N's CAIs. Instead of a DP I'm going to get headers and probably a Cat-Back system.

[bighurt130]

your gona want to get a bigger DP or the cat back wont make any difference plus the stock one will choke off your headers

[Joose]

I know, thought about that after I posted.

[71duster340]

lol....zzperformance...pleace dont tell this guy to jump on that bandwagon

[foxized]

ZZP is badass.. wtf are you smoking

[BogerD17]

As long as its only exhaust parts he's fine. Anything else (esp pcm's)...run away!

[samjones2004]

sounds good, did you remove the cat or res?

[Joose]

No, not yet at least. Not sure what I'm doing next. Just put a WizAired CAI in earlier today. So, either more exhaust work, plugs and a 180 t-stat, or an Aeroforce just so I can start scanning for KR and whatnot.

[samjones2004]

yea smart choice, Aeroforce is a good idea, i need to get one ASAP, think my zzp pcm gave me too much kr. not sure tho.

[Joose]

Yeah, I actually may end up going the Twincharge route. Who knows. Keep discussing it on GTP World... I suppose I'll make my decision when I get the money for a big mod.

[7477238]

Sounds mighty mean!
