see cant we 3.1 3.8 owners all get along
but since blue is on this thread id like to pick ya brain for a quick sec
should i get headers.. or Plog and downpipe?
headers is the cheaper route(ebay) but im afraid i will lose low end trq.. and i hear a plog and downpipe supposedly wont do that.. im staying N/A(i think) so what would you do?
oh im a 3.8, not a 3.1
08-07-2011
hey!!
go to your own section
08-07-2011
thought we were all gettin along? see i knew you hate us 3.8er's :P
08-07-2011
haha

OK, since you mention headers, Milzy Motorsports offers ported exhaust manifolds for 3.1/3.4. Whats your take on a DIY porting job on our own manifolds?
08-07-2011
i thought about those but i dont know its wirth it, now that theres headers for 400
08-07-2011
But if I do it myself all it will cost is time. Although I never dropped both manifolds before.

if your feel confident in doing it then yea have at it, better then stock so it cant hurt, unless someone has a reason not to run them

Another bit of stuff that needs clearing up...you don't "lose low end" with headers...it may FEEL like it...but all that headers do...besides gain tons better flowing capabilites over stock...is they shift the powerband UPwards. So it might FEEL like you lost some "low end torque" but in fact it just moved that TQ to the upper RPM range where your factory exhaust failed to move air at. Not only that, but you'll see better MPG's, stonger up top powerband (which most GM V6 cars lacked), a better exhaust note, and a smoother delivery of power...not the sudden "rush" that your used to right off the bat with manifolds. Which will also help from a dead stop...something that I really loved after putting headers on my GTP.

THX blue exactly what i wanted to hear

And you all say I'm hating on 3100's.

blue,
was that for both(any) motors?

What kind of gain do you think the 3.1 will get with headers, cat back exhaust, u Bend delete, 2.5 inch DP with high flow cat, intake, and some sort of cold air intake starting with 175 HP like on my 3.1?Originally Posted by bluegtp91

the downpipe is attachted to the headers
08-08-2011
That's on probably ANY engine...
That's 175 CRANK HORSEPOWER. Which I'd be shocked if your car made 175 to the wheels with all of those things done to it. Seriously. A 2.8 MPFI guy with an intake and custom headers-full exhaust only made 128 WHEEL HP. Granted...the 2.8 was junk...but still.What kind of gain do you think the 3.1 will get with headers, cat back exhaust, u Bend delete, 2.5 inch DP with high flow cat, intake, and some sort of cold air intake starting with 175 HP like on my 3.1?

Thanx. And yes I do realize that is Net 175 HP, not Wheel HP, so regardless of the starting point any guestimate on how much net HP those changes would make without internal changes which I would not do on this engine?
08-08-2011
You know what I'd do if I owned something with a 3100?
Just drive it.
Forealz.
Save your money and get something faster with a better aftermarket...hell even the LS4 cars have a better aftermarket than the 3100...and all the money you toss into it, even if it DID beat a N/A 3800...like I said...your beating something that runs 16's/15's. Which honestly, I wouldn't brag about unless I was 16.
08-08-2011
what do you meen by "snailed"????
08-08-2011
You are totally correct! Not interested in racing the GP, just driving it-it's going to my daughter any how in a year-the less power the better! Thanx.
