new exhaust! Tips? info?

[SilvaMan61]

Sooo my mufflers fell off of my 99 gtp..yeah completley rusted through . So now i am compeled to purchase an after market exhaust.

Im thinking zzp 3in dp catted to the slp powerflo cat back, but im not sure. i wanted to do some headers but their too expensive, plus i dont think ill really need them.. i only plan on goin to a 3.4 pulley W/ supporting mods

hoping some one could help...is there anything i need to kno before making it final..sizing, quality, sound?

still a noob here shed some light on me

oh and if this is in the wrong section i apolagize, feel free to move it.

Nothing sounds good on these cars. I have a set of stock mufflers if you want them.

Catbacks are no good until you hit the 350 FWHP mark...so doubt that your there. 3" catted downpipe is a good start...if you have a dremel you can pull off your front manifold and hog it out for free instead of paying over $100 for a ZZP PLOG...and it maybe nets you 1-2 more HP...the catted 3" DP will make the car a little louder...not much...not enough to be noticeable...you could also...after that...put a glasspack in place of the stock resonator. Doing those 2 things will make a difference. Now go to the General Tech section and read my thread called Safely Modding your 3800.

thanks a ton man.. see that absolutely epidemizes why i joined this forum to begin with

[ZR1Vette09]

see link in sig

for a 3.4 you need either a plog with downpipe or headers. ask around on here, alot of guys recommend going straight with the headers

[rynoman03]

I wish i would have went straight to the headers instead of dicking around with the Ported Exhaust Manifolds and Downpipes. Ehh... I could have save so much money.

[SilvaMan61]

yeah you know i would spring for the headers but their so expensive, im only 19 that type of money is hard to come by.... but it probably will save me some down the road..arrgg idk

[TheOtherNick]

$350 for headers is cheaper than the proflow exhaust.

[SilvaMan61]

oh and rinoman thats one sexyy gtp..reminds me of mine..very similar ( appearance wise atleast)

[SilvaMan61]

i could go for the pacesetters..but the seem to cheap to be really good.. espesially seeing as how i dont have the ability to weld them readily available

[ZR1Vette09]

everyone hates pacesetters, but alot of guys like SS autochrome headers. 350 bucks shipped Turbo Kits, Turbo Manifolds, Import Performance Products, SSAutochrome Inc.

I do not see any headers in the GM section that say they are for the grand prix. Maybe you can post me the link becuase i can't seem to find them. 350 bucks shipped sounds good.

[TheOtherNick]

Your grand prix is a pontiac click on the pontiac symbol. I run them on my car they work good.

[pr84704p]

everything i come across is for 97-03. Im guessing these will not fit an 04.

[TheOtherNick]

Any header for a 97-03 gp will fit an 04+. There is a guy on here running them.

[Ibwrong]

You can call them up.. as 01 said they should fit, there are people running them with no problems.

[pr84704p]

Oh wow that's great. I just got the car and know nothing. Im doing my research and am finding that there are many more parts for the previous gen models.

[TheOtherNick]

Everything in the bottom end will work from the series II 3800 97-03 you just have a drive by wire tb and gen v supercharger.

[SilvaMan61]

so these ssac headers, any leaks like the pacesetters? because i was going to go with a plog and zzp dp but if i can get headers for cheaper then im in

[TheOtherNick]

Mine dont leak.

[SilvaMan61]

is there any welding needed with them..evan just to install? or can it all be done with band clamps?
